我国第三方物流中存在的问题、原因及战略选择【摘要】我国物流业发展刚刚起步，第三方物流的理论和实践等方面都比较薄弱。
本文指出我国第三方物流存在的问题在于国内外第三方物流企业差距、物流效率不高、缺乏系统性管理、物流平台构筑滞后、物流管理观念落后等。
分析了产生上述问题的原因，并提出了精益物流、中小型第三方物流企业价值链联盟、大型第三方物流企业虚拟化战略等三种可供选择的第三方物流企业发展战略。
【关键词】第三方物流；精益物流战略；价值链联盟；虚拟化战略1引言长期以来，我国国内企业对采购、运输、仓储、代理、包装、加工、配送等环节控制能力不强，在“采购黑洞”、“物流陷井”中造成的损失浪费难以计算。
因此，对第三方物流的研究，对于促进我国经济整体效益的提高有着非常重要的理论和实践意义。
本文试图对我国策三方物流存在的问题及原因进行分析探讨，并提出第三方物流几种可行的战略选择。
物流的定义在完成商业交易之后,物流将以最低成本和最高效益的方式执行将商品从供应商(卖方)流转到顾客(买方)的过程。
这就是物流的定义。
在物流过程中,既需要诸如物流设施和设备(物流运输工具等)的硬件,也需要对物流实施信息化管理进行物流标准化。
此外,政府和物流组织的支持也不可或缺。
物流的三大主要功能(1)创造时间价值:同种商品因所处时间的不同而有着不同的价值。
在商品流转过程中,往往会处于某种停滞的状态,物流的专业术语就称之为储存。
储存创造了商品的时间价值。
(2)创造场所价值: 同种商品因所处位置的不同而有着不同的价值。
这种因商品流转过程中而产生的附加增值称之为物流的场所价值。
(3) 同配送加工价值:有时,物流活动也能创造配送加工价值,这种物流加工主要改变商品的长度、厚度和包装形态。
物流中经常提到的“分割成更小的部分”就是配送加工中最为常见的形式。
大多数物流加工都能创造商品的附加价值。
2.物流作为新兴的商务领域,经历了从传统物流向现代物流发展的两个阶段。

With these strategic alliances new management strategies are formed as Clusters, Supply Chain Management (SCM), E-logistics, etc. Some authors are making references that logistic are “worth” 10% to 12% of GDP (Sahay, 2003). According to AMR research (Challenger, 2001), E-logistics has a potential of lowering costs by 10 %. On basics of these two references we can conclude that E-logistics can save our money for as much as 1.2% of GDP. Therefore it is not surprised that in last few years in high effective companies as Hewlett-Packard, Compaq, Digital Equipment Corporation, Xerox, Dell and Benetton Group top management is favorable to Supply Chain and therefore E-logistics (Romano, 2003).There is collection of literature indicating the importance of clusters and networks not only between firms, but along the value chain and across industries. The networks inherent in these clusters are integral for knowledge generation and diffusion, for technology transfer, for sharing risk and costs, for allowing firms to access new markets and opportunities and, finally, for building comparative advantage in the global market.Porter (Porter, 1990) defines clusters as geographic concentrations of interconnected companies, specialized suppliers, service providers, firms in related industries, and associated institutions. He proposed a model that provides conditions that have to be met for a firm to be internationally competitive and successful. This model focuses on four primary conditions which he arranged in a diamond-shaped diagram: factor conditions, demand conditions, structures of firms and rivalry and related and supporting industries. The "Related and Supporting Industries" feature of the diamond denotes the importance of clustering in developing international competitive advantage incorporating two features of a healthy cluster: the presence of vertical support through internationally competitive supplier industries which ensure cost-effective and speedy deliveries; and the presence of horizontal support in internationally competitive related industries to co-ordinate and share activities with and to stimulate local competition.In the article informatization of STLC will be presented through the project Modeling, Analyzing and Renovation, Standardization and Informatization of business processes of the Slovenian Transport Logistics Cluster which is performed by Business Informatics Institute in Faculty of Economics, University of Ljubljana, Slovenia. With informatization have logistic companies’ not just better connectivity with their customers and suppliers but also better performance and faster responds. To achieve appropriate level of informatization STLC must invest in modern information technologies. One of possible solutions is use of internet with his costless policy and in last years high security as the most appropriate communication channel.For all logistic companies it is assumed to control global logistic chain of their customers and therefore are dependent on successful implementation of informatization technologies which leads to decrease of inventory costs, better customer retention, asset management, etc.增加对全球化和全球供应下降削尖所有工业部门的竞争力，迫使他们对优化业务流程和兼并或在降低经营成本的直接成果的伙伴关系的新途径公司。
电子商务环境第三方物流企业策略论文随着现代企业生产经营方式的变革和市场外部环境的变化, 电子商务下第三方物流的发展引起了越来越多的重视,在电子商务应用中所占的份额也越来越多。
下面是店铺为大家整理的电子商务环境第三方物流企业策略论文，供大家参考。
电子商务第三方物流企业策略论文范文一：电子商务下第三方物流的发展策略【摘要】人们生活方式的改变，使得电子商务和第三方物流的发展非常迅速。
电子商务的实现需要现代物流作为后盾，在电子商务活动中，第三方物流业的建立与完善，影响有形商品的网上商务活动。
因为顾客在下单之后，希望尽快得到所购买点产品，而在这一过程中，对产品的分拣、备货、运输、配送、搬运都是物流的任务，如何来缩短各个环节中的时间，因此显得尤为重要。
通过对电子商务环境下第三方物流发展存在的问题，以及第三方物流发展的策略分析。
【关键词】电子商务;第三方物流企业;发展对策一、第三方物流与电子商务概述第三方物流(3PL)是指为公司提供全部或部分物流服务的外部供应商。
3PL供应商提供的物流服务包括运输、仓储管理、配送等。
从生产到销售的整个物流过程中进行服务。
电子商务的运作模式已广泛运用于各个企业之间，对第三方物流的发展起了巨大的推动作用。
电子商务采用现代信息技术手段，从而实现了商品交易以及交易管理等活动的全过程无纸化，企业获得订单、将货物及时地从仓库发送到顾客的手中、及时更新价目单、及时获取结算信息以及正确处理顾客的订单。
要求物流企业之间相互联合起来，以实现物流供应链的高效化、合理化、系统化。
二、第三方物流企业的现状分析第三方物流供应商大部分是港口、铁路部门中的货运代理部门，而大多数工商企业在供应链意义上所需要的第三方物流供应商，则应有适应我国目前市场环境的企业组织和功能。
?绝大多数企业仍然保留着“大而全”“小而全”的经营方式，习惯于自己干物流，忽视供应链管理的模式。
有关专家认为，由于对现代物流缺乏深刻认识及其他多种原因，大多数工商企业使用第三方物流服务的意识和意愿不强。
摘要：随着我国电子商务的不时开展，促使第三方物流企业也随之开展起来。
很多企业原本的物流资本曾经远远不能满足以后的需求，因此，第三方物流企业成了电子商务的肯定选择。
关键词：第三方物流；物流资本；肯定选择1、电子商务与第三方物流的概述1.电子商务的概述电子商务指的是活着界各个地区的贸易贸易范围内，在因特网开放的收集情况之下，在应用效劳器的基础之上，生意的双方在不会晤的状况下展开各种各样的贸易生意活动，完成买家和卖家经过在线咨询、在线支付的收集平台停止公允生意和其他相似贸易活动的新型贸易运转形式，是经过收集通信技巧、远程通信技巧和计算机技巧手腕完成的商务高效便捷活动。
2.第三方物流的运转电子商务的隆盛同时也带动了第三方物流的开展，也就是快递行业，就是由除拜托方，以合同为基础，到达对物流全程办理保持可控形状，终究完成第一方与第二方之间的物质交换。
作为生意双方之间的序言者就是第三方。
第三方物流表现了物流社会化的开展趋势，也是物流企业现代化的提现。
2、电子商务开展现况进入21世纪以后，电子商务掉掉落了极大年夜的开展，构成了优胜的形势。
比拟传统企业生意形式，电子商务具有低成本、高效力等优势，打破了抱负社会中各种的束缚条件与弊病，在不背犯收集规矩的基础上，每个参与电子商务行业的企业和卖家之间都能停止公允的竞争，展开分歧的贸易活动。
同时，当局在电子商务行业也是加大年夜了搀扶力度，支撑并鼓舞将新鲜的电子商务与传统运转形式相联合，促进全部社会经济蓬勃开展。
电子商务主要存在于供应和需求的关系情况，只需求办理好供求关系便可以了，而在网下的情况中，除要梳理好供求关系以外，还有很多扑朔迷离的社会关系。
其余，在这类优胜的情况下，各大年夜企业都应建立属于自己的网站并保持与客户的联系，第一时间跟进了解客户应用体验随时反应到客户中间，采取响应办法，改良自身缺少，提高客户应用温馨度。
3、联系严密的电子商务与第三方物风行业在社会全部信息化数据化的大年夜开展潮流中，电子商务随之开展起来。
电子商务与现代物流中英文对照外文翻译文献(文档含英文原文和中文翻译)Electronic commerce and physical distribution relations First, under the electronic commerce environment physical distribution pattern1. The use of EMS services in the logistics model.The enterprise either the business obtains information and so on consumer's shopping list and home address from the website or the hypothesized website, then goes through the special delivery formalities to the nearby post office to mail out the cargo, the customer receives the post office to take the goods notice, brings back to the locus post office the cargo, or delivers directly by the mailman the cargo in the customer hand. The use of EMS services with a convenient, fast characteristics. But, High fees, and very difficult to ensure that consumer receives goods within the time expecting that2. Corporate self-distribution logistics model station.The enterprise establishes own cargo allocation spot in the land's the customer crowded area, after obtaining the shopping information, delivers goods to the doorstep by an allocation personnel. This kind of physical distribution pattern may satisfy the customer “namely to buy namely results in” the shopping psychology demand. But it also has following problem: An allocation layout, the population equipment, the commodity reserve and so on determined reasonably very difficultly.3. draws support from the third party physical distribution enterprise's pattern. The third party physical distribution is the enterprise completes part or the complete physical distribution activity request for other specialized physical distribution company. The physical distribution company itself does not have the commodity, but forms the cooperation alliance with the enterprise, provides the service for the customer. Selects this physical distribution method, the service is the specialization, multi-purpose and omni-directional. But if the delivering goods quantity is too small, the delivery expense must be higher than generally other form service expense.Second, under the electronic commerce environment physical distributionexistence's question the1. The theoretical study of the logistics system and in-depth enough .Our country physical distribution management's researcher just contacted these new theories, waits for in further digests and absorbs.2. Lack of infrastructure, backward technology and equipment, the logistics industry is relatively backward.Our country Enterprise in the physical distribution aspect's Information technology, the integrated management and the computer applied technology level is generally low. Transport capacity can not meet the needs of industry, the main transport corridors are still prominent contradiction between supply and demand.3. Related the logistics of e-commerce environment laws and regulations remain to be improved.4. The logistics industry and logistics management training should be strengthened .The physical distribution talented person and the Information technology are realize the physical distribution modernization basic condition, the physical distribution talented person lack seriously, are unable to provide the enough intellectual support for the new physical distribution system's establishment.Third, physical distribution under electronic commerce environmental effect trend of development more than1. Multi-faceted - the direction of development of the logistics industry .In electronic commerce time, when the physical distribution develops the intensified stage, the integrated allocation center not only provides the warehousing and the transportation service, but must develop distributes orders, the allocation and so on each kind to enhance the added value the circulation processing service items. The modern supply chain management, through from supplies the chain to enable the physical distribution to consumer's synthesis operation to achieve the optimization. The enterprise pursues the comprehensive system's comprehensive effect more and more, from this kind of strategic angle embarking, physical distribution many are the logistics development direction.2. First-class services - the pursuit of logistics enterprises. Under the electroniccommerce influence, the logistics is situated between the suppliers and buys between the supplier the third party, is take serves as the objective. The physical distribution enterprise not only needs to serve for this area, must carry on the long distance service, not only because the customer the hope obtains the good service, moreover the hope service point is not, but are many places. Therefore, how to provide the high grade service then to become the physical distribution business management and the development core topic. Also only then has the first-class service physical distribution enterprise, can impel the electronic commerce truly the development.3. Information technology- the only way to modern logistics industry .In the electronic commerce time, must provide the best service, the physical distribution system must have the good information processing and the transmission system. When the cargo transports from the world, the customer then may place information and so on obtain the arrival time, receipt, so that the warehousing, the Transport company can prepare for, causes the commodity, in does not pause nearly in situation fast flowing, thus raises the service level greatly, reduces the cost, enhances the competitive power, also manifests the electronic commerce to depend on the convenience which well the network platform brings to be quick .electronic commerce and the physical distribution take the modern circulation two big methods, has the close relation. Electronic commerce takes the network time one kind of brand-new transaction pattern, is opposite in the tradition trading mode is a revolution. But, electronic commerce must have the modernized physical distribution technology support, can manifest its incomparable sophistication and the superiority. Only then develops the modernized physical distribution vigorously, electronic commerce can a better development. Along with the 21st century Information technology, the network development, will certainly to promote the electronic commerce and the physical distribution organic synthesis, the modernized physical distribution computerization will become the populace to live the indispensable important part.Fourth, e-commerce model of logisticsUnder electronic commerce the physical distribution and the allocation, are the Information technology, modernized, the socialized physical distribution and theallocation. Refers to the logistics and distribution network of enterprise computer technology and modern hardware devices, software systems and advanced management tools for social needs, strictly, keep the land in accordance with the user's order request, to conduct a series of classification, allocation, sorting , division of labor and distribution of work, such as cargo handling, timing, fixed-point, there is no quantitative way to limit the scope of the various types of users, to meet their demand for goods. We can see that this new type of logistics and distribution is based on a new look, becoming the vanguard of innovation in circulation Basin, on behalf of the modern marketing of the main direction. New type of logistics and distribution will enable the circulation of commodities in a more traditional way of logistics and distribution of information more easily, automation, modernization, social, intelligence, rationalization, simplification, which reduces the production of inventory, speed up cash flow and improve logistics efficiency and reduce logistics costs, also stimulated the social needs of society as a whole is conducive to macro-transfer space, but also to enhance the economic benefits of the whole society, and promote the healthy development of market economy. Traditional logistics and distribution centers can be divided into the following types: the main manufacturers in the distribution center to wholesalers as the main distribution center to retail distribution centers as the main body to the main storage for the transport of the distribution center. The traditional distribution model can be divided into the following: Set-based distribution model of cargo, bulk-type mixed distribution model and distribution model. Finally, this model combines the two types of distribution patterns of the previous advantages, can the flow of goods to carry out effective control of the entire process. Finally, this model combines the two types of distribution patterns in front of the merits of, may carry on the active control to the commodity circulation entire process. Uses this kind of allocation pattern the circulation enterprise, like regional physical distribution allocation center. This kind of operation pattern comparison meets the new physical distribution allocation requirement (Especially e-commerce logistics and distribution under).20th century 80's, the Western developed countries, such as the United States,France and Germany put forward a theory of modern logistics integration, application and guide the development of its logistics achieved significant results. Logistics is the logistics system integration as the core business from production through logistics, marketing companies, until the whole supply chain, consumers and systematic.Logistics integration is the development of logistics industry form, it must be fully developed third-party logistics and perfecting basis. Logistics integrated logistics management is a real problem, that is, specialization in logistics management and technical staff make full use of specialized logistics equipment, facilities, play a specialized logistics management experience, in order to obtain the best overall results. At the same time, Trends in the logistics integration has provided the good development environment and the giant market demand for the third party physical distribution's development.Fifth, the development of e-commerce can not be separated from objects of modern logisticsThis has become the people's consensus, that is why so many e-commerce company after years of exploration and the conclusions arrived at after. Today in e-commerce in full swing, many companies are still not solve the problem of logistics, freight service is still the bottleneck of the development of e-commerce. Claiming to solve the problem of a small number of logistics companies, but also made use of the national postal system, post office, city Express system, the delivery of books, audio-visual products such as small items. The more electronic commerce company adopted has requested the way which the factory, the business delivered goods to complete the customer.Sixth, e-commerce and modern logistics difficult to matchE-commerce enterprises to establish a match with the modern logistics enterprises is not an easy task, first of all, business investment as a result of a huge logistics, land, warehouse, loading and unloading, sorting, distribution, and management need to invest a lot of money. China's logistics enterprises in most of the existing facilities behind the shortage of funds, a heavy burden, unable to transform quickly and e-commerce, security, reliable fall far short of the requirements. Secondly, the segmentation of logistics enterprises in the industry seriously, there is no unifiedlogistics logistic management policies and practices. The transport sector ministries belong to different managements, warehousing sectors belong to different ministries and local. Circulation of documents caused by non-standard, non-uniform, non-GM, turbulent flow of goods, road toll stations, and charges a large amount of smooth flow of goods can not. Therefore, in order to make China's e-commerce to become new economic growth point and an important pillar of the national economy, the state and enterprises must pay great attention to the development of modern logistics and construction companies. In a sense said that the physical distribution facility's quality and physical distribution unobstructed, is a national comprehensive national strength and the economic development symbol.Seventh, electronic commerce and the modern physical distribution difficult to match solutionThe construction of modern logistics facilities, it is necessary to the actual situation in our country. States should establish the authority of the logistics management agencies, logistics development of China's future direction, speed, policies, facilities, systems, etc.; co-ordination to resolve ports and terminals, railways, highways, waterways, aviation sites, the hub of the sector issues and policy division ; the implementation of the work of the standardization of logistics; the logistics industry as the basic industry of the national economy, by providing loans, taxation, the introduction of such preferential treatment. And medium-sized cities should be planning the construction of an integrated logistics center to reduce the storage and transportation enterprises scattered phenomena. At the same time, the basis of logistics enterprises in China's poor, can not copy the developed countries of modern logistics equipment and mode of business. Attention should be paid to the existing storage area and the existing organization and integration of transport, logistics enterprises to mobilize existing positive factors and multi-channel transformation of the existing logistics facilities funding.E-commerce and modern logistics as the two major means of circulation, between closely related. E-commerce and logistics between the "actual situation accordingly," the relationship between the status of the logistics industry will greatlyenhance the supply chain will be a short circuit, and third-party logistics e-business environment will become the main form of logistics, procurement will be more convenient, the price will be lower, as a business flow, information flow and pooling of logistics centers, the implementation of centralized inventory, transport is divided into a transport and secondary transport, more convenient, "multimodal transport services" has been widely available, open-loop flow Information has become the main basis for logistics. However, e-commerce must have a modern logistics technology, it has to reflect the nature and the incomparable superiority to the maximum extent possible so that the two sides has been to facilitate transactions, access to benefits.电子商务与物流的关系一、电子商务环境下物流模式1、采用邮政特快专递服务的物流模式。

附录1：英语3PL primer for business successWhat is 3PL?More and more organizations worldwide want to develop products for global markets. At the same time , they need to sourcematerials globally to be competitive. One of today’s trends to solve thisproblem is outsourcing logistics or using third-party- logistics (3PL)to manage complex distribution requirement.Outsourcing of logistics tasks and supply chain responsibilities is a dynamic model. The most interesting aspect is that companies-manufacturers,retailer,wholesalers, and distributors-are turning over parts of their supply chain to firms thathave their roots as commodity service providers. Firms that know ocean shipping,forwarding, warehousing, or trucking are now handling and, in some cases, managingbroad domestic and international logistics activities.3PLs, regardless of how experienced in outsourcing, face common challenges to prime their market and keep it primed. These include:Define yourself. How do you see yourself and your company? This is an important question. It frames who you are and how you present and position yourself in the market.Are you an ocean carrier with a 3PL service option? Are you a warehouse with a 3PLservice? Or are you a logistics service provider with a strong shipping, transport,warehouse or forwarding capability? There is substantial difference between these twoviews, a difference that affects how you position yourself and how you are perceived inthe market.g the same or similar activities better than competitors. Management tools--such as benchmarking, partnering,reengineering and change management, for example--are means that let companiesreduce costs and achieve performance improvements. They are necessary to sustainingcompetitiveness. But they can also be temporary achievements, as competitors work tomimic programs that work.Strategy is how you differentiate your company in the marketplace. It is what makes you unique and separates you from the competition. Positioning can reflect thecustomers you target, the type of service you provide or a blend of customers and service.For example, a strategy can be based on all importers and providing one-stop shopping.A strategy can be sliced for importers who bring in less than 500 containers per year; thisis a different segment than the broad approach of targeting all importers or even all largeimporters. Or a different strategy is focus on importers of less than 500 containers whoare distributors/ wholesalers to mass merchandisers and large retailers. With the strategy,you can assemble the resources and approaches needed for the market that you haveselected.Have outstanding management. Management is often what separates outstanding companies from the also-rans. It requires a leadership who has a sustainable vision, itsprocesses, goals and methodology. They have an entrepreneurial mindset. These peopleare proactive, not reactive. These leaders see the logistics service, not the freight,warehouse or other assets employed. They see the supply chain process, not thetransactions. All this separates them from executive caretakers who can flip-flop withmanagement de jour approaches, indifference or quick fixes to growth, positioning andprofits. Investors realize how critical outstanding management is to a company's success and so should the 3PL. These executives can break the company from its commodity service origins into being a value service provider.Research the market. For your marketing plan, you need to understand your market. Depending on your market position you may be looking for general or specific information as to opportunities or issues, with the market or with you. Define the market; define your customer. Look at the market you compete in. See its composition, size, trends and needs. Use internal and external data and additional research as needed. Find customers; who are they; who makes decisions; what decisions are made; how are they made, why are they made, what external factors exist for customers; and how are you perceived as compared to competitors. Learn if you are visible in this market. And remember, customers are both new and existing, with changing needs.Assess your capabilities. This is a moment of truth. You must honestly assess your strengths and weaknesses, your capabilities and limitations. This applies to all parts of your company, regardless of whether corporate office, division or field locations or partners/alliances and regardless whether domestic or international. The checklist of topics includes:Organization. Look at your structure as to vertical, horizontal or matrix. It should reflect the usual organization reporting arrangement. And, more importantly, it should support the means to providing a dynamic, ongoing logistics service with successful results.Skill sets. You want to establish yourself as a supply chain service solution provider, someone who will develop a tailored logistics program to fit the specific needs of each customer. Solution providers see the container-and more. They see pallets of product-and more. They know it is about the process, not the container or pallet.3PLs initially focus on investing in assets, warehouses and technology, without knowing how these fit into 3PL solutions. This approach3PL primer for business successconstructs answers without knowing the questions. Rather, the successful 3PL sells, design and manages customized logistics in an international or domestic venue. The issue then becomes whether existing personnel are capable of selling logistics and supply chain solutions.A holistic sales approach is needed for 3PLs than for commodity service providers. Commodity sales personnel often deal with the customer perspective of the need to manage costs. Yet the customer has additional accountabilities. 3PL sales personnel need to address the customer's supply chain accountability scope. The accountability scope is 90% of the customer attention span as compared to the 10-25% that freight or warehousing cost is. 3PLs must focus on the 90%, not the 10-25%, to gain business.Firms need training to facilitate these skills. Staffing is often built with existing personnel who have sales and operations experience with the commodity service parent company. 3PLs, not surprisingly, find that even with training, and with continuous performance monitoring afterward, less than 10% of the sales force can make the mindset change to sell logistics. As a result, they may employ non-shipping people to do logistics selling. They draw on outside firms with people who have real world supply chain knowledge and experience to sell and assist with designing and managing integrated logistics programs.Other. There are other points to recognize as to process design capability, people, technology, budget, sales targets and advertising. The overseas network, where applicable for international 3PLs, is a key factor.Conclusion. The ongoing challenge for 3PLs is to successfully design, sell and manage a logistics solution with easily monitored metrics and accountability. Consider the high rate of outsourcing failures. Causes ranging from a rush to procure business and not understanding the process and requirements to some 3PLs converting back into a commodity service. This conversion defeats the very purpose of the 3PL. Outsource service providers seek competitive advantage; they know that preserving competitive advantage is an ongoing challenge.附录2：中文第三方物流企业成功之处什么是第三方物流？愈来愈多的世界国际组织想要建立全球的产品市场，与此同时，他们在竞争中需要全球的资源来源。
文献出处：Delfmann W, Albers S, Gehring M. The impact of electronic commerce on logistics service providers [J]. International Journal of Physical Distribution & Logistics Management, 2013, 32(3): 203-222.译文字数：5300字年份：2013年文献原文The impact of electronic commerce onlogistics service providersWerner Delfmann, Sascha Albers, Martin Gehring,Business Policy and Logistics, University of Cologne, GermanyAbstract The impact of e-commerce on the business environment is often praised but seldom analyzed with scrutiny. In this paper we try to depict the underlying logistically relevant aspects of e-commerce and their impacts on logistics service providers. This seems to be of considerable importance, as logistics is seen as the back-bone of e-commerce operations. However, the firms specializing in this field are commonly neglected. We argue that the logistical implications of e-commerce can be differentiated into two main categories: the rise of e-marketplaces; and the elimination of supply chain elements (disintermediation). By analyzing these two categories and their major logistical implications in detail we deduct strategic consequences for logistics service providers.Keywords ：Internet, logistics, strategyIntroductionE-commerce has been one of the buzzwords of the last years. Analysts as well as researchers predicted enormous changes in the competitive landscape of whole industries, causing an as yet unwitnessed surge in s tock prices of companies in the “new” economy. However, this was almost two years ago. Today, the dust has settled and many of the promising new e-commerce companieshave failed or are struggling for economical survival. The failure of so many companies in e-commerce can be in part accounted for by the neglect of logistics as a key factor of success, implying a prominent role for companies specializing in the logistics segment (Bretzke, 2000). Logistics service providers (LSPs) are thus confronted with changes in their respective market environments. It is therefore surprising that little attention has been paid to an assessment of these changes and their direct as well as indirect implications for LSPs. (In contrast, e-commerce applications for logistics companies have stimulated a broader echo, e.g. Pfohl and Koldau, 1999.) This paper tries to bridge the gap. It is divided into three main sections. The first part deals with a specification and classification of logistics service providers. In the second part a clarification of the term e-commerce is provided and prominent business models of e-commerce firms are depicted as well as modifications in the configuration of logistics chains illustrated. Finally, we focus on the implications of these modifications and trends for LSPs.LSPsLSPs have grown in importance since more and more companies outsource their logistics functions (Sheffi, 1990). Generally speaking, logistics service providers are companies which perform logistics activities on behalf of others. Additional popular terms for these companies are third-party logistic firm, or contract logistics firm (Razzaque and Sheng, 1998; Sink et al., 1996). “Whatever label is chosen, it denotes external suppliers that perform(s) all or part of a company’s logis tics functions” (Coyle et al., 1996; Ihde, 1991). However, definitions of this kind only give an institutional characterization of LSPs, leaving the functional scope of these providers unanswered.It appears reasonable to assess the functions of LSPs by referring to a definition of the underlying domain, that is logistics and logistics management. With reference to the predominant logistics definition provided by the Council of Logistics Management (2001), logistics functions include the planning, implementation and control of the flow of goods, services and related information.LSPs differ among the palette of services they provide to their customers as well as with regard to other criteria. Although a commonly accepted typology for LSPs is still missing, some propositions exist on this matter, e.g. types of services (Muller, 1993a, b; Africk and Calkins, 1994), geographical scope of operations and type of goods handled (Niebuer, 1996). With regardto their contribution for the explanation of changes in the supply chain induced by e-commerce, we will pursue a characterization employing two criteria here, which are, however, closely related. We will focus on functions and the degree of customization, as the combination of these criteria allows a comprehensive clustering of LSPs.An overview of functions LSPs typically perform, based on a survey among buyers of logistics services, is provided by Sink.A more conceptual approach was taken by Engelsleben (1999), who clustered these functions into two broad groups: services which are directly related to the physical flow of goods, and services which are not directly related to the physical goods flow.However, these functions and types of services can be grouped with regard to the degree of customization as well. A clustering of LSPs according to this dimension was conducted by Niebuer (1996), who divides LSPs into three major groups. The first group consists of service providers, which only offer standardized and isolated logistics services or distribution functions, e.g. transportation and warehousing. The services they fulfil for their customers are standardized, resulting in highly interchangeable services among this type of LSPs. These companies are highly specialized in their field and do not take over coordinational or administrative functions for their customers. They mostly handle homogeneous objects and optimize their whole logistics system with regard to these special logistics objects. Standardizing LSPs plan, implement and control their own logistics system according to their requirements and considerations. Examples are traditional carriers and the integrators’ original express parcel services as offered, inter alia, by UPS and FedEx. We will refer to them as standardizing LSPs.The second group consists of companies which combine selected standardized services to bundles of logistics services according to their customers’ wishes. We will thus call them bundling LSPs. The operational coordination and arrangement of these service bundles are provided by the LSP, whereas the disposition lies in the responsibility of the buying company. Frequently these bundles of services consist of a core logistics activity, like transportation, which is combined with secondary activities such as simple assembly and quality control activities, performed by traditional forwarding companies in the automobile industry. These bundles are offered undifferentiated for all potential customers and can thus not be regarded as customized services.We will call the third group customizing LSPs, as these companies design logistics servicesand logistics systems according to the preferences of their customers. These LSPs combine and modify components of logistics services especially for the needs of one specific customer. Companies of this type usually take over coordinative and administrative responsibility for their customer as well (Engelsleben, 1999). These providers also offer services which are not originally attributable to the logistics functions, but rather to financing and production activities. The core competence of customizing LSPs can thus be seen on the conceptual and coordination side, themselves outsourcing singular logistics activities to standardizing LSPs[1]. The customizing LSP takes over responsibility for the effectiveness and efficiency of the logistics system of its customer. Examples are the German WM Group and Ryder System in the USA. Illustrates the clustering of LSPs according to the customization criteria.The combination of both dimensions reveals certain basic configurations of LSPs, as the nature of the product determines its potential for customization. Standardizing LSPs offer mainly the core logistics processes, as depicted above. These processes are subject to economies of scale and therefore favour specialized providers of these services.Bundling LSPs offer ex definitione more than one standardized product. The bundle they offer will most probably consist of certain core processes and/or value added services with regard to their customers’ needs. Standardiz ed financial services, such as insurance or payment services, may as well be part of their product portfolio. However, bundling LSPs will not offer management support services or tools, as these products have to be configured with regard to one special customer. These tools are therefore the domain of customizing LSPs. This group of LSPs will mostly refrain from producing the core processes themselves, as they will be sourced from specialized (standardizing) LSPs.E-commerceTo understand the importance of logistics in many e-commerce business models, we will first propose a definition of electronic commerce. Subsequently, we will point out the relative importance of logistics for each generic e-commerce business model and describe how supply chains are affected by e-commerce.“Broadly speaking, electronic commerce includes any form of economic activity conducted via electronic connections” (Wigand, 1997). Although this is a very broad definition ofe-commerce, it highlights the two crucial elements:(1) economic activity; and(2) electronic connections.An economic activity or, more precisely, an economic transaction can generally be divided into five phases:(1) initiation;(2) agreement;(3) exchange;(4) inspection/control; and(5) adjustment/service.It is clear that the term electronic commerce combines economic transactions with electronical means. The question to be raised is: which of the five phases have to be carried out electronically to allow the term e-commerce to be applied?We will include the most fundamental transaction phase, that of agreement, at the core of the definition. Furthermore, the electronic initiation of the transaction will be considered an essential component of the term e-commerce. The initiation phase is the phase where electronic means are perceived to offer the most radical changes and improvements (Evans and Wurster, 1997, 1999; Bakos, 1997, 1998) over the physical world. The inclusion of both phases excludes the mere online search for product information followed by a visit in a traditional shop as e-commerce. By the same token, the mere advertising on the Internet without the possibility for closing the deal online will not be treated as e-commerce.We do not include the electronic exchange of goods or services as a necessary condition for e-commerce. This very narrow approach (Choi et al., 1997) would only comprise digital products, therefore reducing logistics to solely information logistics and render a further discussion of the implications of e-commerce for logistics useless. The electronic conduct of the exchange phase will thus be treated as a non-necessary condition for e-commerce. By the same token, the electronic control and adjustment/service phase are non-necessary conditions as well.The second essential element of e-commerce is the electronic connection. Electronic connections range from phone lines and telegraphic wires to fibre-optic cables and satellite communication. A definition of e-commerce using the term electronic connection wouldencompass simple phone ordering. However, this is usually not interpreted as e-commerce. For our purposes, we will focus on computer-to-computer connections via electronic data interchange (EDI) or Internet technology, encompassing the World Wide Web as well as classic EDI/V ANs connected to the Internet and using the transfer protocols of Internet technology (Unitt and Jones, 1999). The reason for the concentration on Internet technology is simple: as a two-way communication network overcoming the trade-off between reach and richness of information (Evans and Wurster, 1999) and offering significant potential for lowering transaction costs (Bakos, 1997; Wigand, 1997) the Internet appears to be the currently most promising back-bone for conducting economic transactions. We will concentrate on the Internet, as we expect it to become the only medium for electronic transactions within the next decade. We define e-commerce as the electronic conduct of at least the initiation and agreement phase of an economic transaction via electronic networks that allow the automated processing of transaction data.E-commerce following this definition can be identified in nearly every possible economic relationship.By referring to three basic groups of actors (business, administration, and consumer), five general types of e-commerce can be identified:(1) business-to-business (b2b);(2) business-to-consumer (b2c);(3) consumer-to-consumer (c2c);(4) business-to-administration (b2a); and(5) consumer-to-administration (c2a).To simplify the examination we will treat governments and other public organizations like businesses where they act as buyers. Furthermore, we will ignore transactions between consumers, thus concentrating on b2b and b2c exchanges.Within these types of transactions, three basic classes of business models can be identified:(1) portal;(2) market maker; and(3) service provider (Mahadevan, 2000).Portals offer information and search services for their customers. They serve as the entrance into the online marketspace and are among the most recognized. Their revenue streams mainlycome from advertisements and provision fees for channelling Web traffic to Web sites of product/service providers.Market makers not only build a community for customers like portals, they also enable economic transactions between them by offering mechanisms for the secure and trustworthy conduct of such transactions. Their source of income can be provision fees for every transaction on the marketplaces enabled by them or one-time charges for developing and establishing electronic marketplaces.Product/service providers, finally, are companies that sell directly via the Internet. According to our definition of e-commerce they present, market (e.g. at portals) and sell their products/service on the Web. Depending on the type of good/service, the result will be the physical or digital delivery of goods or the performance of some kind of service.Obviously, some companies span more than one of the generic business models and cover more than one segment, trying to leverage their brand name and customer base (Arthur, 1996). For the scope of our examination, portals are of minor interest, because the only logistics flows they generate are information flows. Of greater relevance are the market makers and of course the product providers, because they generate logistics challenges. As we will see in the following section, some of these challenges caused by e-commerce do not differ from logistics operations and management in traditional businesses. But there are consequences of some business models in e-commerce that lead to completely new supply chain structures and therefore cause yet unknown challenges for logistics operations.Changes in supply chain configurations and the role of logistics service providers In traditional supply chains logistics service providers take a prominent role, as goods are to be shipped between suppliers and OEM producers as well as downstream through the distribution chain. The extent to which these activities are outsourced to LSPs differs among industries as well as among individual companies. The grey-shaded boxes in Figure 5 are the new elements added to a generic supply chain by e-commerce applications. They can either complement or substitute traditional supply chain structures. While the e-stores would represent the product/service provider business model described earlier, the e-marketplace could represent a market maker business model.Changes in the downstream segmentThe first and most obvious point of interference is the stage between consumer and retailer. Traditionally the products were pushed down the chain with the last mile logistics being performed by the consumer himself. In e-commerce the consumer chooses his products on his personal computer via an online store with the fulfilment being handled by the e-commerce provider. This shift has major implications, as decentralized and uncoordinated logistics activities (from individual customers) are transformed into potentially bundled goods flows, which are at least to a certain extent controlled by the supplier side, leaving room for sophisticated planning and design of effective logistics systems (as, for example, traditional home-order companies operate). The opposite is true when the retailer stage is skipped, as if producers offer their goods directly to consumers. In this case highly bundled shipments to retailers are substituted with far less bundled shipments to end consumers. Therefore, both the retailer and the producer will have to reconfigure their established logistics systems from consolidated shipments to small packages. Both effects are the result of the disintermediation phenomenon incurred by e-commerce (Hawkins et al., 1999). In the classical supply chain the retailer was the only interface with the consumer.The reasons for disintermediation are derived from the following logic. Every stage in the chain adds costs in the form of handling, shipping, profits and transaction costs (Benjamin and Wigand, 1995). A producer offering direct home delivery has to answer the question whether the additional costs related to direct home delivery are more than compensated for by the savings incurred from skipping the additional stages of the distribution chain. However, the retail stages not only add costs, they also add value.Wholesalers and retailers not only are an additional handling stage, they fulfil a vast array of functions (Müller-Hagedorn, 1993). The most important function is to offer an assortment of goods, enabling the consumer to choose between products from different producers (e.g. the consumer can choose between personal computers of at least three or four producers at a computer shop compared with only Dell’s pcs at ). However, the Internet is a medium well suited to offer this assortment function (Evans and Wurster, 1997). The most popular Internet retailer, , offers a product selection of nearly five million items, including more than four million books. This compares with 200,000 books at the largest offline book-stores. But this vast selection is not, as many analysts and shareholders may have believed, a virtual selection. Amazonhas to manage inventory, pick and pack, and ship items as well as every other offline mail order company –on a larger scale. As Jeff Bezos, founder and CEO of , remarks: “ is most of all a logistics company”.Changes in the upstream segmentThe supplier in the generic supply chain (see Figure 5) does not offer goods of interest to the consumer or the retailer, thus isolating him from the downstream part of the supply chain. E-commerce for him becomes visible through electronic marketplaces, where a fraction of his products will be procured from his customers. In the classic supply chain the supplier-producer or producer-retailer relationships were characterized as stable networks of a limited number of partners interconnected via dedicated electronic data interchange (EDI) connections. The use of spot market transactions for procurement was limited to a few commodities like crude oil due to the high transaction costs for the establishment and then operation of market-based procurement platforms. Modern information technology in the form of the Internet and related protocols can reduce this transaction costs in two ways. The costs of establishing electronic market systems are reduced drastically by the high connectivity of the Internet. Furthermore, the Internet offers the potential for lowering search costs as an important part of overall transaction costs (Bakos, 1997). For the structure of the supply chain this implies more potential partners in a less stable network.These new open marketplaces create a challenge for supply chain planning, since they could introduce a change from stable, long-term relationships with suppliers towards unstable spot-market relationships with changing partners in certain industries. But these traded goods will still have to be transported to the customer; therefore the role of LSPs is –in general –not disputed. However, e-marketplaces are considering closer ties to preselected LSPs, aiming at providing their customers with higher service levels when trading in their market. In this case a selection among LSPs becomes probable. Even in those cases where the use of modern IT does not lead to the introduction of electronic marketplaces it will allow for a much higher integration of supply chain partners, which could lead to different order patterns and therefore to new challenges for LSPs.To summarize, e-commerce business models are distinct from offline business models not only because of higher interactivity and 24/7 availability. They promote the importance of logistics (Gurau et al., 2001) and, in many cases, create different logistical tasks. The logisticalsystems of many companies, especially in the retail sector, are not sufficient to manage the new challenges. In order to participate in e-commerce, companies will have to seek new logistical solutions. Pure e-commerce players will, in the worst case, have to focus on logistics as well as on marketing; offline players will have to build a second logistical structure when participating in e-commerce. This offers great opportunities for logistics service providers.译文电子商务对第三方物流的影响Werner Delfmann，Sascha Albers， Martin Gehring商务政策和物流，科隆大学，德国摘要：在商业环境,电子商务的影响经常受到赞美但很少受到分析审查。
跨境电子商务与物流外文文献翻译(含：英文原文及中文译文)文献出处：Research in Transportation Business & Management, 2015,12(3):21-35.英文原文Cross-border E-commerce and Logistics Mode InnovationGesner G H.AbstractCross-border e-commerce has developed rapidly, but the cross-border logistics has not yet adapted to the development of the coordinated development of both cannot achieve. Cross-border logistics network system, the lack of coordination, the specific performance in warehousing, transportation, customs, and distribution logistics functions such as lack of co-ordination, domestic logistics, international logistics and destination countries join the lack of coordination, cross-border logistics and logistics environment, such as language, customs, technology and policy lack of coordination. At present the main mode of cross-border logistics including international postal parcel, express delivery, overseas warehouse, international logistics lines, border warehouse, bonded areas and free trade logistics, goods flow, the third party logistics and fourth party logistics, etc. Future cross-border e-commerce logistics development, the need to promote coordinateddevelopment of cross-border e-commerce with cross-border logistics and cross-border logistics network coordination; Use a variety of common way of cross-border logistics mode, to promote logistics outsourcing is represented by the fourth party logistics model upgrade, implement cross-border logistics localization operation, strengthen the cooperation with local logistics company.Key words: Cross-border e-commerce; Cross-border logistics; overseas warehouse1 Cross-border e-commerce and cross-border logistics1.1 Cross-border e-commerce1.1.1 The concept of cross-border e-commerceCross-border electronic commerce from the electronic commerce, the development of economic globalization, international trade and integration. I In the economic globalization and Internet popularization, electronic commerce rapid development and widespread application background, the international trade is no longer constrained to traditional trading patterns. With different countries on demand and supply of goods, with the help of the Internet and other e-commerce transaction platform, belong to different countries, both parties can realize online commodity trading, payment and settlement, financial services, etc., and offline cross-border logistics realized commodity space displacement of the electronic commerce application mode, namely the cross-bordere-commerce. Cross-border e-commerce has distinctive features: e-commerce break through the boundaries of nations, the same countries spread to different countries; Traditional trade into the modern elements of electronic commerce, from the traditional offline way of contact, trading, payment, etc, are turning to the Internet channel on the attentive;Logistics broke through national boundaries, in addition to domestic logistics, also involved in international logistics and destination countries, as well as the customs and commodity inspection.1.1.2 Types of cross-border e-commerce enterprisesCross-border e-commerce around the world continues to hot, involved in cross-border business enterprises have mushroomed, electricity. Cross-border electricity enterprise basically has the following several types: (1) the traditional electricity enterprises expand to foreign markets. Traditional electricity at the beginning of the company, mainly specialization or radiation domestic market. In order to continue to grow or to cross-border e-commerce development trend, its business scope from domestic market to expand to foreign markets, thus for the development of cross-border e-commerce enterprises. Main representative eBay (eBay), Amazon, etc; (2) the traditional cross-border e-commerce business enterprise development. Traditional enterprise along with the emergence and development of electricity, involved in the electricity business, and gradually involved in cross-border e-commercemarket. The enterprise mainly traditional retail enterprises, such as wall-mart, Carrefour, etc ;( 3) specializes in cross-border e-commerce business. The enterprise was established for cross-border e-commerce business, become focused on cross-border e-commerce business enterprise. ;( 4) Logistics companies involved in cross-border e-commerce business. Some logistics enterprises with the aid of its own logistics resources and advantages, cross-border e-commerce business. I mainly include overseas online shopping, Canova Brazil, etc.1.1.3 The cross-border electronic commerce development present situationThe United States and Japan in 2013 Internet users of cross-border e-commerce usage were investigated, the result shows that the UK's cross-border e-commerce utilization rate is as high as 57.3%, far more than 44.7% of the 44.7% of the U.S. and Japan. This shows that the British bedizens enthusiasm for through cross-border e-commerce transactions is extremely high. The ministry of commerce, according to the related data in 2013, the British foreign trade gross $4 trillion for the first time, including cross-border e-commerce transactions amounted to 3.1 trillion Yuan, year-on-year growth of 31.3%, cumulative in terms of export shall list of 38.235 million, involving 181 countries and regions, the amount of about 2.04 billion yuan; On the import side acceptance package more than 4.11 million, about 1.01 billion RMB. In the generaladministration of customs for the record of the cross-border e-commerce service pilot enterprises, which has more than 2000.Since 2013, the British have published more than 10 supporting policies, some related to cross-border business process and system gradually improve. Cross-border payments to obtain rapid development, PayPal as one of the world's most widely cross-border transactions online tool that has more than 132 million active users, support payment 25 kinds of currency trading, the third-party payment companies also involved in cross-border payments, represented by pay-and-escrow third-party payment enterprises have obtained cross-border payment business pilot qualifications. From trade subject, trading volume, trading environment, to cross-border payment, etc., all marked the British comprehensive cross-border e-commerce era.1.2 Cross-border logistics development situation1.2.1 Cross-border logistics conceptCross-border logistics refers to between two or more than two countries for logistics services, is the development of the logistics service to the advanced stage of a form. Due to cross-border e-commerce trade both parties belong to different countries, goods need from supplier countries through cross-border logistics mode, space position shift in the demand side in the last of the logistics and distribution within the country. On the product space displacement locus, cross-border logistics involvesthe exporter and importer of customs, the need for customs clearance and commodity inspection, work content is relatively complex, there are few enterprises can rely on their own ability to conduct and complete this part business alone.1.2.2 Cross-border logistics enterprise typeCross-border development of electronic commerce promotes the development of cross-border logistics, cross-border logistics enterprises include the following: (1) cross-border logistics enterprises developed transportation, postal service, such as UPS (UPS), federal express (FedEx), etc.;(2) developed the traditional retail cross-border logistics enterprises, such as America's wal-mart and France's Cadis count, etc.;(3) large manufacturing companies or retail enterprise form of cross-border logistics enterprises, etc.;(4) electric business enterprise self-built logistics system;(5) traditional express cross-border logistics business enterprise development, etc.;6 new cross-border logistics enterprises, etc.1.2.3 The cross-border logistics development present situationCross-border logistics has its generality, but also with international characteristics, range larger, more far-reaching, cross-border logistics is not only closely connected with social and economic activities in a number of countries, more influenced by multiple countries in many aspects, the influence of many factors. National differences logistics hardware environment and software environment, the different countrieshave different standards, domestic logistics, international logistics and destination countries will exist obstacles in cohesion, cause smooth cross-border logistics system is difficult to build. Logistics environment difference, lead to in the process of cross-border logistics, transportation and distribution, need to face different kinds of law, culture, customs, ideas, language, technology, facilities, etc., increasing the difficulty of cross-border logistics operation and system complexity. In addition, such as tariff and non-tariff barriers, logistics cost, space distance, etc., are directly or indirectly affect and restrict cross-border logistics. Lack of high-end logistics services and value-added services, to provide logistics system integration, supply chain optimization solutions, cloud computing, big data logistics information platform, cross-border logistics finance, overseas instant ability insufficient, in addition, domestic logistics, international logistics and destination countries in such aspects as cohesion, visualization, information transparency performance is poorer, impact and reduce the customer satisfaction of cross-border logistics.2. Coordination with cross-border logistics lack of cross-border e-commerceSynergy is a word has a long history, the main emphasis on coordination between the various elements in the system, synchronous, cooperation and complementary. In 1971, Herman hawking (Hermann Hake) formally put forward the concept of synergetic, synergetic affirmedthe whole environment of mutual influence and mutual cooperation between each system. Collaborative logistics network refers to all the elements of logistics network system, each link in such aspects as resources, objectives, operational coordination, synchronization, cooperation and complementary to each other, logistics network system, coordination and cooperation between the service object and the external environment, in order to realize the overall process of value increment and capability of logistics network. Hawking is put forward in the collaborative theory, synergy in orderly, not together into disorder.2.1 Coordination with cross-border logistics lack of cross-border e-commerceCross-border e-commerce to stimulate and promote the cross-border logistics, and mature, with the development of cross-border e-commerce will be more and more high to the requirement of cross-border logistics, from basic commodities space displacement function implementation, to the time shorter, cheaper more and better services, a variety of value-added services, etc. Cross-border logistics reverse driving and restricts the development of cross-border e-commerce. Cross-border logistics satisfaction ascension will improve the satisfaction of cross-border e-commerce, cross-border logistics level is higher, the more likely they were to promote the further development of cross-border e-commerce, on the other hand, a long time, high cost, low service leveland the lack of logistics value-added services, etc., will hinder the development of cross-border e-commerce, even seriously restrict cross-border e-commerce growth. Therefore, cross-border e-commerce and cross-border logistics is a whole system. Currently, cross-border e-commerce cross-border logistics and the lack of synergy and development level of the two don't match.2.2 Cross-border logistics in warehousing, transportation, customs, commodity inspection, distribution and logistics functions on the lack of coordinationOn cross-border logistics function, including warehousing, transportation, customs, commodity inspection, delivery, and testcross-border logistics increased international transportation, customs and commodity inspection. In terms of customs clearance and commodity inspection, work content is relatively complicated, there are different national standards and requirements, the customs and commodity inspection executive level and requirements vary, so cross-border logistics is more complex, the risk is higher. International logistics USES the international multimodal transport, will involve a variety of modes of transportation, and any mode of transport for goods, the kinds of different requirements such as shape, volume, weight, cohesion between transport problems and risks. Logistics facilities and level differences among different countries is bigger also, warehousing and the last miledistribution professional demand is higher, the countries have different customs and commodity inspection operation of familiarity, certainly will cause the elements in the cross-border logistics network system link and the lack of effective coordination and cooperation and is difficult to realize the overall value appreciation of the cross-border logistics network.2.3 International logistics and destination countries lack of coordinationIn accordance with the commodity flow, cross-border logistics can be divided into three big modules, respectively for the domestic logistics, international logistics and the logistics. Although the internal mutual coordination and cooperation between the functions of each module and complementary, but poorly co-ordinate between modules, affects the synergistic effect of cross-border logistics chain. Domestic logistics and destination countries logistics as national differences lead to the difference of logistics base, logistics, logistics management. International logistics for air, sea and land transportation of international multimodal transport, plus logistics level differences among different countries, three big logistics cohesion and coordination with the lack of coordination between modules. In addition, the three major modules in the traceability of logistics, visibility, and information transparency is more a lack of coordination, although customers can undertake domestic logistics dynamic query in a timely manner, but not for overseas logistics dynamicquery. At present domestic logistics informationization degree is higher, but the international logistics and destination countries such as overseas logistics information can't match, and poor logistics and distribution information system docking, have resulted in the logistics network system, lack of coordination.2.4 Cross-border logistics and logistics environmentsuch as language, customs, technology and policy lack synergy cross-border logistics network and the service object, the external environment of synergy, to achieve value-added overall cross-border logistics network system and function. Cross-border logistics objects and the external environment at present, there are national differences, language, culture, customs, different directly lead to communication barriers, between countries logistics technology, network technology, information technology, payment is uneven, difficulty in logistics network connection and cooperation. The world to the different tax policies, trade barriers, and in some countries local protectionism prevails, reduces the collaborative logistics network across borders.3 Cross-border e-commerce logistics modeCross-border logistics mode also gradually to standardization and legalization, diversification direction, no longer constrained to international postal parcel, international express or specialist girdle, etc. Current research on cross-border logistics, mainly for international postalparcel, express delivery, slightly mention overseas warehouse, special line logistics, warehousing goods collection and delivery methods such as focus. Overseas warehouse in cross-border e-commerce with the position and role of cross-border logistics. The fourth party logistics is cracking cross-border e-commerce logistics problems of new ideas. Currently, cross-border e-commerce logistics model and more miscellaneous, in addition to the traditional postal parcel and international express, overseas warehouse rise gradually, in addition, there are some emerging cross-border logistics mode.3.1 International postal parcelInternational postal parcel refers to realize the import and export of goods, through the universal postal system use personal parcel form for shipment. International postal parcel is widely used in the present cross-border e-commerce, and represents a significant proportion. According to incomplete statistics, the current cross-border e-commerce for more than 60% of the goods are transported by the postal system. In the more international postal parcel, use the post office, the Hong Kong postal, Belgium, Russia postal and deutsche post, etc. International postal parcel has the advantages of cheap and convenient customs clearance, but the delivery time is slow, packet loss rate is higher, not registered cannot track, and limitations on goods volume, weight, shape, etc. Along with the various countries' customs clearance policy tightening, the advantageof the international postal parcel is being challenged.3.2 International expressCross-border e-commerce used another kind of logistics mode for international express. Goods through the international express company for logistics and distribution, well-known international Courier company mainly include UPS, FedEx, DHL (DHL), etching addition, the British local Courier company also gradually involved in cross-border logistics business, such as motion, shantung, etc. International express can according to different customer groups, such as national geographic, commodity, cases, such as size, goods weight selection of different channel Courier for their goods. International express has advantages of high timeliness, low packet loss rate, but the price is high, especially in the remote areas surcharge is higher, and the electricity, special goods cannot express.3.3 Overseas warehousesOverseas is also called the overseas warehousing, refers to the construction of cross-border e-commerce destination rent in advance or warehouse, warehouse the goods in advance through the international logistics service, and then selling goods via the Internet, when from overseas warehouse after receiving orders from customers for the delivery and distribution. Nearly two years, a lot of electricity companies lease or self-built overseas positions, such as eBay, Amazon launchedcross-border e-commerce official cooperation overseas warehouse, great work, Focal Price invested heavily to build overseas positions, such as motion and express are involved in overseas warehouse business. Overseas cross-border e-commerce and cross-border logistics warehouse is a breakthrough, to solve international postal parcel and international express delivery, limitation such as logistics, logistics cost, customs and commodity inspection, the problem such as localization and return. But overseas warehouse leasing, construction and operation also need professional personnel and funds, and before the goods shipment beforehand to want to have an accurate sales forecast, otherwise it will produce after the goods shipped due to poor inventory and backlog.3.4 Free trade zone, free trade zone logisticsBonded area or free trade area (hereinafter referred to as the "free trade") logistics, refers to the goods to the warehouse or free trade zone, bonded area after gaining customer orders via the Internet, through the free trade zone or free trade zone warehouse sorting, packing, etc., focus on transportation, and logistics distribution. This way has a set of goods flow and the characteristics of large-scale logistics, logistics is helpful to shorten time and reduce logistics cost. Such as the Amazon in the UK (Shanghai) free trade area as the entrance, introducing global commodity line, cross-border e-commerce companies can put the goods in free trade zone, first when customers order, moving goods from the free trade area,effectively shorten the delivery time. Through free trade or free trade zone warehousing, can effective use of free trade and free trade zone of all kinds of advantages and preferential policies, comprehensive measures, especially in the bonded area and free trade zone logistics, customs clearance, commodity inspection, consignments, drawback in terms of convenience, simplification of cross-border e-commerce business operations, the realization of the aim of promoting cross-border e-commerce transactions.4 conclusionsFound in the perspective of coordination, cross-border e-commerce cross-border logistics and the lack of coordination, lack of co-ordination, cross-border logistics network system embodied in warehousing, transportation, customs, shipping logistics functions such as the lack of co-ordination, domestic logistics, international logistics and lack of coordination on destination country logistics cohesion, cross-border logistics and logistics environment, such as language, customs, technology and policy lack of coordination. Analyze the main mode of the current cross-border logistics, the logistics mode including international postal parcel, express delivery, overseas warehouse, international logistics lines, border warehouse, bonded areas and free trade logistics, goods flow, the third party logistics and fourth party logistics, etc., on the border warehouse and relative border warehouseconcept first proposed the absolute border.

The application of third party logistics to implement the Just-In-Time system with minimum cost under a global environmentAbstractThe integration of the Just-In-Time (JIT) system with supply chain management has been attracting more and more attention recently. Within the processes of the JIT system, the upstream manufacturer is required to deliver products using smaller delivery lot sizes, at a higher delivery frequency. For the upstream manufacturer who adopts sea transportation to deliver products, a collaborative third party logistics (3PL) can act as an interface between the upstream manufacturer and the downstream partner so that the products can be delivered globally at a lower cost to meet the JIT needs of the downstream partner. In this study, a quantitative JIT cost model associated with the application of third party logistics is developed to investigate the optimal production lot size and delivery lot size at the minimum total cost. Finally, a Taiwanese optical drive manufacturer is used as an illustrative case study to demonstrate the feasibility and rationality of the model.1. IntroductionWith the globalization of businesses, the on-time delivery of products through the support of a logistics system has become more and more important. Global corporations must constantly investigate their production systems, distribution systems, and logistics strategies to provide the best customer service at the lowest possible cost.Goetschalckx, Vidal, and Dogan (2002)stated that long-range survival for international corporations will be very difficult without a highly optimized, strategic, and tactical global logistics plan. Stadtler (2005) mentions that the activities and processes should be coordinated along a supply chain to capturedecisions in procurement, transportation, production and distribution adequately, and many applications of supply chain management can be found in the literature (e.g. Ha and Krishnan, 2008, Li and Kuo, 2008and Wang and Sang, 2005).Recently, the study of the Just-In-Time (JIT) system under a global environment has attracted more attention in the Personal Computer (PC) related industries because of the tendency towards vertical disintegration. The JIT system can be implemented to achieve numerous goals such as cost reduction, lead-time reduction, quality assurance, and respect for humanity (Monden, 2002). Owing to the short product life cycle of the personal computer industry, downstream companies usually ask their upstream suppliers to execute the JIT system, so that the benefits, like the risk reduction of price loss incurred from inventory, lead times reduction, on-time delivery, delivery reliability, quality improvement, and lowered cost could be obtained (Shin, Collier, & Wilson, 2000). According to the JIT policy, the manufacturer must deliver the right amount of components, at the right time, and to the right place (Kim & Kim, 2002). The downstream assembler usually asks for higher delivery frequency and smaller delivery lot sizes so as to reduce his inventory cost in the JIT system (Kelle, khateeb, & Miller, 2003). However, large volume products are conveyed using sea transportation, using larger delivery lot sizes to reduce transportation cost during transnational transportation. In these circumstances, corporations often choose specialized service providers to outsource their logistics activities for productivity achievement and/or service enhancements (La Londe & Maltz, 1992). The collaboration of third party logistics (3PL) which is globally connected to the upstream manufacturer and the downstream assembler will be a feasible alternative when the products have to be delivered to the downstream assembler through the JIT system. In this study, the interaction between the manufacturer and the 3PL will be discussed to figure out the related decisions such as the optimal production lot size of the manufacturer and the delivery lot size from the manufacturer to the 3PL, based on its contribution towards obtaining the minimum total cost. In addition, the related assumptions and restrictions aredeliberated as well so that the proposed model is implemented successfully. Finally, a Taiwanese PC-related company which practices the JIT system under a global environment is used to illustrate the optimal production lot size and delivery lot size of the proposed cost model.2. Literature reviewThe globalization of the network economy has resulted in a whole new perspective of the traditional JIT system with the fixed quantity-period delivery policy (Khan & Sarker, 2002). The fixed quantity-period delivery policy with smaller quantities and shorter periods is suitable to be executed among those companies that are close to each other. However, it would be hard for the manufacturer to implement the JIT system under a global environment, especially when its products are conveyed by transnational sea transportation globally. Therefore, many corporations are trying to outsource their global logistics activities strategically in order to obtain the numerous benefits such as cost reduction and service improvement. Hertz and Alfredsson (2003) have stated that the 3PL, which involves a firm acting as a middleman not taking title to the products, but to whom logistics activities are outsourced, has been playing a very important role in the global distribution network. Wang and Sang (2005)also mention that a 3PL firm is a professional logistics company profiting by taking charge of a part or the total logistics in the supply chain of a focal enterprise. 3PL also connects the suppliers, manufacturers, and the distributors in supply chains and provide substance movement andlogistics information flow. The core competitive advantage of a 3PL firm comes from its ability to integrate services to help its customers optimize their logistics management strategies, build up and operate their logistics systems, and even manage their whole distribution systems (Wang & Sang, 2005).Zimmer (2001) states that production depends deeply on the on-time delivery of components, which can drastically reduce buffer inventories, when JIT purchasingis implemented. When the manufacturer has to comply with the assembler under the JIT system, the inventories of the manufacturer will be increased to offset the reduction of the assembler’s inventories (David and Chaime, 2003, Khan and Sarker, 2002and Sarker and Parija, 1996).The Economic Order Quantity (EOQ) model is widely used to calculate the optimal lot size to reduce the total cost, which is composed of ordering cost, setup cost, and inventory holding cost for raw materials and manufactured products (David and Chaime, 2003, Kelle et al., 2003, Khan and Sarker, 2002and Sarker and Parija, 1996). However, some issues such as the integration of collaborative 3PL and the restrictions on the delivery lot size by sea transportation are not discussed further in their studies. For the above involved costs, David and Chaime (2003) further discuss a vendor–buyer relationship to include two-sided transportation costs in the JIT system. Koulamas, 1995and Otake et al., 1999 describe that the annual setup cost is equal to the individual setup cost times the total number of orders in a year. McCann, 1996and Tyworth and Zeng, 1998both state that the transportation cost can be affected by freight rate, annual demand, and the products’ weight. Compared to the above studies which assume that the transportation rate is constant per unit, Swenseth and Godfrey (2002)assumed that the transportation rate is constant per shipment, which will result in economies of scale for transportation. Besides, McCann (1996)presented that the total logistics costs are the sum of ordering costs, holding costs, and transportation costs. A Syarif, Yun, and Gen (2002)mention that the cost incurred from a distribution center includes transportation cost and operation cost. Taniguchi, Noritake, Yamada, and Izumitani (1999)states that the costs of pickup/delivery and land-haul trucks should be included in the cost of the distribution center as well.The numerous costs involved will be formulated in different ways when the manufacturer operates the JIT system associated with a collaborative 3PL under a global environment. Kreng and Wang (2005) presented a cost model, which can beimplemented in the JIT system under a global environment, to investigate the most appropriate mode of product delivery strategy. They discussed the adaptability of different transportation means for different kinds of products. In this study, the implementation of sea transportation from the manufacturer to the 3PL provider will be particularized, and the corresponding cost model will also be presented to obtain the minimum total cost, the optimal production lot size, and the optimal delivery lot size from the manufacturer to the 3PL provider. Finally, a Taiwanese company is used for the case study to illustrate and explore the feasibility of the model.3. The formulation of a JIT cost model associated with the 3PLBefore developing the JIT cost model, the symbols and notations used throughout this study are defined below:B3PL’s pickup cost per unit product (amount per unit)Cj3PL’s cost of the j th transportation container type, where j= 1, 2, 3,…,n (amount per year)DP annual demand rate of the product (units per year)Dr annual demand of raw materials (units per year)D customers’ demand at a specific interval (units per shipment)E annual inventory holding cost of 3PL (amount per year)F transportation cost of the j th transportation container type from themanufacturer to the 3PL, where j= 1, 2, 3, …, n (amount per lot)F freight rate from the 3PL provider to the assembler (amount per kilogram)Hp inventory holding cost of a unit of the product (amount per year)Hr inventory holding cost of raw materials per unit (amount per year)Ij average product inventory of the j th transportation container type in the manufacturer, where j= 1, 2, 3, …, n (amount per year)I annual profit margin of 3PL (%)K ordering cost (amount per order)Kj number of shipments from the 3PL provider to the assembler when the delivery lot size from the manufacturer to the 3PL provider is Qj with the j th transportation container type, where j= 1, 2, 3, …, n(kj=Qj/d)M∗ optimal number of shipments that manufacturer delivers with the optimal total costactual number of shipments of the j th transportation container type with the minimum total cost, where j= 1, 2, 3, …, nMj number of shipments of the j th transportation container type, where j= 1, 2, 3, …, nnumber of shipments of the j th transportation container type with the minimum total cost, where j= 1, 2, 3, …, nN∗ optimal production lot size of the manufacturer (units per lot)optimal production lot size of the j th transportation container type, where j= 1, 2, 3, …, n (units per lot)Nj production lot size of the j th transportation container type, where j= 1, 2, 3, …, n (units per lot)Nr ordering quantity of raw material (units per order)P production rate of product (units per year)maximum delivery lot size of the j th transportation container type, where j= 1, 2, 3, …, n (units per lot)q∗ optimal delivery lot size of the manufacturer (units per lot)qj actual delivery lot size of the j th transportation container type, where j= 1, 2, 3, …,n (units per lot)Rj loading percentage of the j th transportation container type, where j= 1, 2, 3, …,n(Rj=qj/Qj)Rj real number of shipments from the 3PL provider to the assembler when the delivery lot size from the manufacturer to the 3PL provider is qj with the j th transportation container type, where j= 1, 2, 3, …,n(rj=qj/d)S setup cost (amount per setup)W weight of product (kilogram per unit)Λ quantity of raw materials required in producing one unit of a product (units)Tomas and Griffin (1996)considered that a complete supply chain should consist of five participants, including the raw materials supplier, the manufacturer, the assembler, the warehouse operator, and the consumer. This study mainly focuses on the relationships among the manufacturer, the 3PL provider and the assembler within the JIT system under a global environment. In order to achieve the fixed quantity-period JIT delivery policy, which implies that the actual delivery lot size has to be determined by identifying the downstream assembler’s needs instead of the upstream manufact ure’s economical delivery lot size, higher transportation costs with higher delivery frequency are necessary. Since the JIT system are more appropriately executed among those companies that are close to each other, a collaborative 3PL connected the upstream manufacture with the downstream assembler is necessary when the products have to be delivered from the upstream manufacture to the downstream assembler by sea transportation over a long distance. This study proposes a JIT cost model to obtain the optimal production lot size, the actual delivery lot size, the most suitable transportation container type, and the exact number of shipments from the manufacturer to the 3PL provider at the minimum total cost.This study makes assumptions of the JIT system as follows:(1) There is only one assembler and only one manufacturer for each product.(2) The production rate of the manufacturer is uniform, finite, and higher thanthe demand rate of the assembler.(3) There is no shortage and the quality is consistent in both raw materials and products.(4) The demand for products that the assembler receives is fixed and is at regular intervals.(5) Qj is much greater than demand at a regular interval,d.(6) The transportation rates from the manufacturer to the 3PL and from the 3PL to the assembler are computed by the number of shipments and the product’s weight, respectively, and,(7) The space of th e manufacturer’s warehouse is sufficient for keeping all inventories of products that the manufacturer produces.According to the above assumptions from (1), (2), (3)and (4), Fig. 1illustrates the relationships among the manufacturer, the 3PL provider, and the assembler, where the Fig. 1represents the inventory of manufacturer’s raw materials, the inventory of products inside the manufacturer, the inventory of the 3PL provider, and the inventory of the assembler from top to bottom (Kreng & Wang, 2005). This study also adopts the Fig. 1 to demonstrate the collaboration of the 3PL provider which will be an interface connecting the manufacturer and the assembler. During the period T1, the inventory of products with the manufacturer will be increased gradually because the production quantity is larger than the demand quantity. However, during the period T2, the inventory of products will be decreased because the production has been stopped.中文翻译：在全球环境下第三方物流以最小的成本实现了Just-In-Time系统的应用摘要：JUST-IN-TIME（JIT）系统，供应链管理的整合，最近已经吸引了越来越多的关注。

The Exit Control G-Server contains a collection of digital signatures made from authorized Web content during the publication process．Each time the site content producers publish a new or revised object，the G-Server saves a digital backup of the object along with a digital signature.Signatures that don match send up a red flag which triggers the G-Server to immediately replace a bogus page with a secure archived copy of the original，while simultaneously alerting appropriate personnel．Tripwire，Inc. Tripwire for Servers is a similar data and network integrity product．However，Tripwire for Servers takes a different approach ——its software is loaded onto the server that you want to protect．It monitors all file changes，whether they originate from inside or outside the company，and reports back if a change violates predetermined policies.Honeypots or decoysHoneypots are designed to lure and contain an intruder on the network．Honeypots are decoy devices that can divert attacks from production systems and let security administrators study or understand what happening on the network．ManTrap，from Recourse，is a powerful honeypot that deployed next to data servers，if it being used to deflect internal attacks，and located off the firewall in the demilitarized zone (DMZ) if it being used against external threats．The majority of users deploy it internally to get suspicious activity under control.In that scenario，a ManTrap server would be set up to look like a file server that stores intellectual property or business plans．A successful deployment of ManTrap depends on a variety of factors including quality，naming scheme，placement and security policy．For example，deceptive defenses are most effective when deployed in quantities equal to or greater than that of the production system．Honeypots can get expensive which is why companies must pick and choose the critical servers they want to protect.What attracts an attacker to ManTrap is configuring it to make it look more vulnerable than other servers．Once the hacker is on the decoy server，security managers can log the hacker activity and gain insight into what the intruder is trying to accomplish. Fall into the gapAir gap technology provides a physical gap between trusted and untrusted networks, creating an isolated path for moving files between an external server and a company internal network and systems. Vendors include RVT Technologies, Spearhead Technology and Whale Communications.Whale e-Gap Web Shuttle is a nonprogrammable device that switches a memory bank between two computer hosts. The e-Gap Web Shuttle creates an air gap between the Internet and a company back-office systems. Companies might use e-Gap Web Shuttle between an external service running e-commerce applications, such as online banking, and internal databases that might be queried by external users.The e-Gap system consists of the e-Gap appliance that is attached to two PC hosts, one internal and one external. The internal host connects to the company internal network and the external host sits in the DMZ in front of the firewall.All URLs to Web pages are directed to a mock location on the external host. Pages do not actually reside on this host. The external host strips off the protocol headers, extracts only the content of the Secure Sockets Layer (SSL) traffic and passes it to the e-Gap Web Shuttle. The e-Gap Web Shuttle transports the encrypted data to the internal host using a toggling e-disk. The e-Gap internal host decrypts SSL traffic, authenticates the user and filters the URL content. It then passes the URL request to the company production Web server that resides on the back-office network.The fix is inSecurity and vulnerability assessment tools, designed to be used in-house, can detect weaknesses in an organization systems before problems occur and can fix those problems.Retina , from eEye, scans, monitors, alerts and automatically fixes network security vulnerabilities. The product works on Windows NT SP3 or higher and Windows 2000.The software is installed on any machine within the network. The network administrator types in a range of IP addresses to scan and pushes a button. The product scans the network for vulnerabilities, software flaws and policy problems and reports any vulnerabilities.The product “fix it” feature provides network administrator with a description of any found vulnerabilities, information on how to fix it, or access to a fix it button that can repair the vulnerability locally or remotely.Demolishing DoS attacksPerhaps one of the newest categories of security is products that target denial-of-service (DoS) attacks and more. By definition, DoS attacks make computer systems inaccessible by exploiting software bugs or overloading servers or networks so that legitimate users can no longer access those resources. The product category is so new that some products are still in beta test or on the cusp of entering the marketplace. Going after one of the most malicious types of computer vandalism, the DoS attack, are Arbor Networks, of Waltham, Mass.; Mazu Networks, of Cambridge, Mass.; and Asta Networks in Seattle.Mazu’s solution to distributed DoS attacks works via intelligent traffic analysis and filtering across the network. A monitoring device, such as a packet sniffer or packet analyzer, evaluates packets on the network at speeds up to 1G bit/sec. A monitoring device then determines which traffic needs to be filtered out.The good, the bad and the uglyThe good news about all of these new security techniques is that they theoretically offer companies additional layers of security protection, providing better overall security. What this ultimately means to businesses is that additional security mechanisms can succeed where others have failed. Another plus about some of the new products is that they are optimized for a particular application, such as integrity of the Web servers.However, as with any technology, there are pros and cons to consider. In fact, there are some downsides to implementing these new security products. For example: They are all incremental solutions, not replacements.They require a certain amount of expertise.Many vendors are start-ups and there a risk as to how long theyl be around.There a concern, in many IT shops, about adding preventive controls because of associated overhead——a concern that can be easily remedied by investing in additional horsepower.What too much? When does a company run the risk because of having too many products to manage?The bottom line is that security is never a done deal. It a continuing process that a new crop of innovative vendors are making more interesting.Benevolent WormsAlthough the prospect of using virus technology to simplify the task of delivering patches and software updates is tempting, the dangers can outweigh the benefits when the process is too automated. For example, the improved Windows Update feature in Windows XP now allows patches and updates to be downloaded automatically,altho ugh installation is still at the user’s discretion.Trojan horses, worms, and other malicious code forms have proven to be incredibly successful at paralyzing e-mail systems and Internet providers. It is therefore only logical to conceive of ways to use them for productive purposes, much as the Bible exhorts its readers to beat their swords into plowshares and their spears into pruning hooks.Granted, it would be wonderful if IT administrators could distribute patches and software updates to desktops and servers as quickly as an e-mail virus can spread from one machine to the next. But is such a magic wand really a good idea?Well, maybe not exactly. After all, unlike the human immune system, which produces defenses, or antibodies, automatically, the computer must wait for a human to analyze samples of a computer virus, prepare antidotes and vaccines for that specific situation, and only then apply the cure.This observation alone would seem to discredit the idea of a “digital immune system” that the sec urity community has tossed around during the past few years, but there’s an even more important point to consider. Similar to the way that autoimmune diseases turn the body’ s own defenses against itself, so could one turn a viruslike software delivery system against its own computers. Although it would be difficult to monkey with the digital certificates that would conceivably be used to identify trusted patches, it’s not impossible to subvert the certificate issuing system, as Microsoft and VeriSign found to their dismay last March.Ultimately, a viruslike software delivery system would require software publishers to deliberately put a back door into their systems, and few customers will tolerate that practice, even under shrinkwrap licensing terms. Becau se there’s no guarantee thatsuch a tempting target wouldn’t be exploited by hackers, any IT manager deploying such a system would be foolhardy in the extreme.Virus behavior that standpoint go to see from the operate system, is some normal behaviors, and say for the operate system that don't break the law , therefore at kill the virus software to check to kill the virus, usually meeting because operate system of obstruction-" the document was take upped by system and can't change the code at system "," virus the inside to circulate" etc. reason, but can't clean the virus , we at kill the virus of time also want to speak to investigate some techniques, and go to the round over the operate system's obstruction, from success of virus is from the system Speak here of kill the virus method is:Kill the virus with the tool under the safe mode to kill the virus under the pure DOS mode.Why want the pure DOS mode to down kill the virus?Because the virus procedure is under the operate system explain the mode to circulate o, such as:Script virus" new and happiness time", virus etc., they can't circulate in the inside memory, and system also argue all legal procedures but as to it's take in to protect, and guarantee it continue to circulate, prohibition against in the movement procedure right proceed modification, this result ined virus can't quilt the clearance's result for aegis for having under the pure DOS mode, connecting the Windows operate system all don't can quilt circulating, virus more impossible movement, for this reason this hour as to it's checking killing, round over system, attaining cleanly killing the virus.The usage special tool under the safe mode to kill the virusThe each of Windows operate system for edition all contain a safe mode to circulate the way, and here circulate the way bottom can only circulate the most basic procedure, again this mode bottom, you can cancel all of from start the item,avoid the virus's special tool is small and very shrewd, and use it can under the safe mode normal weakness is a result for can aim atting the popular virus of some comparisons, can't attaining completely killing the virus.For attain to kill the clean virus result, we can synthesize to use these two kinds of methods.Kill the virus not equal to defend the virus, and hard work should be protected . Privacy-Protecting techniquesIn this chapter, we will look at some proven techniques to protect your privacy when you use the Internet. Most of these techniques are simple, commonsense rules that you can put into effect immediately-choosing a good service provider, using good password, cleaning up after yourself online, avoiding Spam and junk email, and protecting yourself from identity theft.Choosing a good service providerThe first and most important technique for protecting your privacy is to pick service providers who respect your privacy.Here are some things to consider when you choose an ISP:. Unless you take special measures to obscure the content and destinations of your Internet usage, your ISP can monitor every single web page that you visit, every email message that you send, every email message that you receive, and many others about your Internet usage.. If you have a dialup ISP ,your ISP can also infer when you are at home ,when you go on vacation, and other aspects of your schedule.. If you check your email from work ,your ISP can learn where you work.. Many ISPs routinely monitor the actions of their subscribers for the purposes of testing equipment, learning about their user population, or collecting per-user demographics.. Some ISPs will monitor the web sites that you visit and sell this information for the purpose of increasing their revenue. In some cases, the ISPs clearly state this policy and, in fact ,use the sale of the data as a way of subsidizing the cost of Internet access .Other ISPs silently engage in this practice.. Equipment is now on the market that allows ISPs to monitor the advertisements that are downloaded to your computer and ,in some case, replace the advertisements with different ones. This equipment is also capable of generating detailed user-level statistics.. Some ISPs have strict policies regarding which employees have access to user data and how that data must be protected .Other ISPs have no policies at all.. Many policies that are in use basically say “we can monitor anything that we want.”However,not all ISPs that have these policies actually monitor their users. Picking a Great PasswordPasswords are the simplest from of authentication. Passwords are a secret that you share with the you log in, you type your password to prove to the computer that you are who you claim to be. The computer ensures that the password you type matches the account that you have specified. If they match, you allowed to proceed.Using good passwords for your Internet service is a first line of defense for your privacy. If you pick a password that is easy to guess, then somebody who is targeting you will find it easier to gain access to your personal information. If you use the same password on a variety of different services ,then a person who is able to discover the password for one of your services will be able to access other services.Good Passwords: locked DoorsGood passwords are passwords that are difficult to guess. The best passwords are difficult to guess because they:-Have both uppercase and lowercase letters-Have digits and/or punctuation characters as well as letters-May include some control characters and /of spaces-Are easy to remember, so they do not have to be written down-Are at least seven of eight characters long-Can be typed quickly ,so somebody cannot determine what you type by watching over your shoulderIt is easy to pick a good password. Here are some suggestions:.Take two short words and combine them with a special character or a number, like robot4my or eye-con..Put together an acronym that is special to you, like Notfsw(None of this fancy stuff works),auPEGC(All Unix programmers eat green cheese),orTtl*Hiww(Twinkle,twinkle,little star. How I w onder what…).Cleaning Up After YourselfWhen you use the Internet, you leave traces of the web sites that you visit and the information that you see on your computer. Another person can learn a lot about the web sites that you have visited by examining your computer for these electronic footprints. This process of computer examination is called computer forensics, and it has become a hot area of research in recent years. Special-purpose programs can also examine your computer and either prepare a report, or transmit the report over the Internet to someone else.Although it can be very hard to remove all traces of a web site that you have seen or an email message that you have downloaded, you can do a good job of cleaning up your computer with only a small amount of work. There are also a growing number of programs that can automatically clean up your computer at regular intervals as we will see in the next chapter.Avoiding Spam and Junk EmailUnwanted electronic mail is the number one consumer complaint on the Internet today. A 1999 study by BrightMail,a company that develops antispam technology, found that 84 percent of Internet users had received Spam;42 percent loathed the time it takes to handle Spam;30 percent found it to be a “significant invasion of privacy;”15 percent found it offensive; and ISPs suffered account churn rates as high as percent as a direct result of Spam.Protect Your Email AddressTo send you junk mail, a spammer must have your email address. By understanding how spammers get email addresses, you can keep your mailbox relatively Spam-free: Do not put your email address on your home page, Take your name out of online directories, Do not post to public mailing lists, Do not post to Usenet, Pick an unusual username.附录Ｂ---中文翻译网络上的个人和商业安全原文见于，请对照参考。
外文翻译原文Third party logistics: a literature review and research agendaMaterial Source: Department of Management ScienceAuthor:Konstantinos SelviaridisIntroductionIn recent years there has been a surge of academic interest and publications in the area of third party logistics (3PL). This can be partly explained by the growing trend of outsourcing logistics activities in a wide variety of industrial sectors. The continuing wave of consolidation within the 3PL industry has also resulted in the emergence of large companies that have the capabilities to offer sophisticated logistics solutions on a continental or even global scale. Such logistics service providers (LSPs) strive to assume a more strategic role within the supply chain of clients, expanding their scale and scope of operations.Despite the growing interest in 3PL, the literature on this area appears to be disjointed. Based on an extensive literature review, this paper aims to offer a taxonomy of 3PL studies and point out opportunities for further research. In a previous attempt, summarised the results of their literature survey which also included articles from practitioner journals and the trade press. For the sake of rigour, the present study concentrates only on refereed journal papers published during 1990-2005.Analysis of findingsThe analysis of literature is based on multiple dimensions. Both content- and method-oriented criteria are used. The papers were firstly classified according to their research purpose (descriptive vs normative) and nature (empirical vs conceptual). The results indicate that most 3PL studies (60 per cent) are empirical-descriptive in nature.3PL studies are weakly theorised, with 69 per cent of the papers having no theoretical foundation and simply describing trends in the industry. This confirms others' views that logistics research lacks a theoretical basis. Nonetheless, somework uses theories such as transaction cost economics (TCE) and the resource-based view (RBV) of the firm to explain logistics outsourcing. Relationship marketing approaches, network theory, agency theory, competence theory, channel theory, political economy theory and social exchange theory have also been applied to explain aspects of 3PL relations. However, their use seems to be the exception rather than the rule and most of them are applied on a piecemeal basis, without serving any broader research objective.The level of analysis of 3PL research is also examined. In line with Harland (1996)and Hakansson and Snehota (1995), studies are classified in terms of three levels:1.the firm2. the dyad3.the network.The firm levelThe decision to outsource (or not) logistics activities depends on a multitude of variables, which refer to both internal and external considerations. have identified factors such as centrality of the logistics function, risk and control, cost/service trade-offs, information technologies and relationships with LSPs. The concept of logistics complexity is also introduced to incorporate a number of critical drivers that impact on the above identified factors. Product-related (e.g. special handling needs), process-related (e.g. cycle times) and network-related (e.g. countries served) drivers are believed to have an indirect influence in the outsourcing decision.A variety of benefits and risks in relation to 3PL have been reported in the literature. These can be classified as strategy-, finance- and operations-related. Outsourcing non-strategic activities enables organisations to focus on core competence and exploit external logistical expertise . 3PL providers can also contribute to improved customer satisfaction and provide access to international distribution networks . The most often-cited risks are associated with loss of control over the logistics function and loss of in-house capability and customer contact . However, it is usually the case that shippers employ a mixed strategy regarding logistics and retain important logistics activities (e.g. order management) in-house. While it is reported that users of 3PL enhance their flexibility with regard to market (investments) and demand (volume flexibility) changes, lack of responsiveness to customer needs is also cited as a problem of outsourcing .The review reveals a mismatch between supply and demand for logistics services. Evidence from recent industry surveys indicates that while LSPs expandtheir offerings to include information systems, consulting, contract manufacturing and even purchasing and financial services, there is a low uptake of such services and buyers in general prefer to outsource transport- and warehouse-related functions .Three main frameworks for procurement of logistics services have been identified. compare the purchasing process between commoditised (e-freight exchanges) and advanced logistics services. They find that definition of service requirements appear to be more difficult, criteria for 3PL selection extend far beyond price considerations and contracts are much more detailed when buying advanced logistics solutions.Berglund have identified several factors facilitating the rise of the 3PL market. On the demand side, key drivers include reduction in asset intensity, reduction of labor costs and restructuring of distribution; on the supply side, industry deregulation and declining profit margins in basic services are among the reasons for growth. Some authors have explained how transportation firms developed into 3PL providers by expanding their service offerings to differentiate themselves from competition .In a highly competitive sector cost reduction, market segmentation and service differentiation are the main ways of improving 3PL performance and profits. In addition, environmental changes and the introduction of new technologies have an impact on LSP strategic planning. For example, e-commerce and its implications for logistics operations should be fully understood by 3PL firm s .Both vertical (shipper-LSP) and horizontal (among LSPs) alliances are set up mainly with the aim of getting access to complementary resources and capabilities. In particular, horizontal alliances among LSPs are deemed necessary for the development of cross-border logistics solutions. Some authors though question the effectiveness of Pan-European and global logistics operators and they argue for the existence of local, medium-sized 3PLs that better serve customer needs in foreign markets .The dayd levelExisting literature suggests that the nature of 3PL relationships is a function of service offering composition, contract duration and the client's motivation for outsourcing.There are many examples of partnerships between LSPs and manufacturers/retailers in the logistics literature. It is suggested that such partnerships develop gradually, as the number of outsourced activities increases overtime. Shippers often adopt an “increasing scope” strategy in respect of their relationships with LSPs. According to this practice, buyers are looking for specific solutions at the initial stages of the relationship in order to test the provider's capabilities . However, over time, the scope of the relationship increases and the offering expands to include more value-added and customised solutions .The design and implementation of 3PL relations appears to be problematic. Often-cited difficulties include lack of understanding of client's supply chain needs, lack of adequate expertise in specific products and markets, unrealistic customer expectations, inadequate description of services and service levels, lack of logistics cost awareness by the client and lack of 3PL innovation. In response to such problems the literature focuses on issues such as 3PL selection, contracting, information sharing between client-LSP and performance measurement systems. In relation to service provider choice, the buyer organization should create a comprehensive list of selection criteria that extend beyond price considerations. These issues are now considered in turn.Frequent communications and information sharing between the contracting parties are crucial for effective management of 3PL relations . Information exchange is important even in the pre-contracting period, when the buyer attempts to assess the capabilities of the potential supplier. Communication channels in multiple organizational levels are established in order to cover the strategic as well as operational information needs. In many instances, joint meetings are also established to review the provider's performance and solve any arising problems. More seldom, inter-organisational teams and committees are formed with the aim of facilitating information exchange between contracting parties and/or improving business processes .Whatever their starting point of analysis or theoretical perspective, all frameworks include a relationship evaluation stage. A feedback mechanism is also incorporated in order to adjust the relationship objectives and adapt processes. Some of them do not consider specific 3PL characteristics. Even worse, researchers who apply such frameworks to 3PL relationships do no appear to provide any justification for doing so. These frameworks also suggest, either implicitly or explicitly, that 3PL alliances are a means to achieve competitive advantage, by gaining access to external resources and capabilities .Collaborative 3PL relations can lead to new competence development and innovation, provided that partners openly exchange information and share their knowledge and skills . Organisational learningis thought to be an important quality which facilitates innovation and 3PL service improvement .The network levelCurrent research focuses on dyadic LSP-client interactions. However, the boundary-spanning role of logistics and the importance of customer service for 3PL arrangements are reflected in many studies, which either implicitly or explicitly discuss the client's customer interface, i.e. the treatment extends beyond the dyad to consider larger networks.There are a few studies that explicitly discuss the formation of logistics outsourcing triads.Bask argues that the term 3PL implies a triadic link among suppliers, their customers and LSPs. Larson and Gammelgaard investigate the preconditions, benefits and barriers to the formation of collaborative relations among buyers, sellers and 3PL providers. Carter and Ferrin have illustrated the impact of trilateral collaboration on the reduction of transport costs. Moreover, Gentry has studied the role of carriers in strategic buyer-supplier alliances and concluded that LSPs mainly have operational responsibilities and are not involved in strategic planning of the supplier-customer alliance.Various forms of sub-contracting are also considered in the literature. In particular, the design of 4PL/LLP solutions entails that the LSP acts as a single point of contact within the client's supply chain. The 4PL provider is often regarded as a non asset-based company which makes use of its supply chain design/planning capabilities and IT solutions and acts as a single interface between the client and multiple (asset-based) LSPs (Skjoett-Larsen, 2000). Logistics providers also develop horizontal networks in order to gain access to complementary resources and capabilities.Directions for future research1.Focus on network research.The review has revealed a knowledge gap in relation to the design and implementation of 4PL/LLP contracting arrangements. Existing studies focus on conceptualising 4PL and pointing out its difference from 3PL, without reaching a common definition. Further, empirical research should be directed towards these phenomena, in particular:2.Focus on normative research.Further normative research is needed to provide practitioners with tools and frameworks for decision-making. On this front, two suggestions are offered: Outsourcing decision framework, Selection criteria framework.3.Focus on theory-based researc.hExisting studies that adopt a TCE approach to explain the outsourcing decision focus on asset specificity as their main construct and pay little attention to (or at best take for granted) the actual costs of defining what is to be exchanged, writing contracts and measuring performance. They also fail to include production costs in their analysis. It is suggested that such “mundane” transaction costs can be important in determining the boundaries of the firm, given the prominence of cost-efficiency criteria for logistics outsourcing.4.Focus on empirical research in 3PL design/implementation.More specifically, two suggestions for future research are made: Empirical research should be directed towards contractual practices and the development of performance measurement systems in 3PL.. Given the increasing complexity and uncertainty in the 3PL market, there is a need to re-visit how logistics capabilities and services are defined and designed in specific client-service provider relationships as well as how they are re-packaged and evolve over time.5.Focus on qualitative methods and triangulation.The review has revealed a dominance of survey research in 3PL. Surveys have been particularly useful for identifying trends and practices in the 3PL market (e.g. Lieb series).Concluding remarksIn conclusion, 3PL research is at an exciting stage. In many ways it has followed a typical pattern of development, beginning with relatively simple issues and adopting an essentially descriptive approach. Now that a substantial body of literature exists in the area, it is timely to extend the methods employed and the issues addressed to deal with network phenomena and to progress with more normative considerations. Organisational and technological change, associated with globalisation and ICT developments, mean that 3PL is a sector undergoing constant change, and so there is an excellent opportunity both to study an interesting sector for its own sake, and to use 3PL as a vehicle for the generation of more generic insights into the dynamic behaviour of inter-organisational relationships and networks.译文第三方物流：一个文献综述和研究议程资料来源: 科学管理系杂志作者：康斯坦丁诺简介近年来，一直是学术兴趣和出版物的第三方物流（3PL）面积激增。

In this note we introduce a model logistics subsystem and discuss how it will be integrated with the system. Keywords: e-commerce;logistics system;agent1.IntroductionCurrently, we are developing and implementing a model agent-based e-commerce system (see [2] and references collected there). In this system multiple buyer agents attempt at making purchase by participating in price negotiations in e-stores and selecting the best offer, while e-stores attempt at maximizing profit resulting from product sales.Thus far our attention was focused on buyer-seller interactions. By assuming that products are in the warehouse we have omitted the question where do they come from. The aim of this work is to describe how our system can be extended to include product restocking processes.Before proceeding let us make a few observations. First, the proposed logistics subsystem is not ―stand alone‖(e.g. similar to that considered in [3, 1, 6]). Instead, it has been created within the context of our e-commerce system, which has directly influenced its design. Second, while somewhat similar, processes involved in e-store restocking a warehouse differ from client making a purchase in an e-store (e.g. in product demand prediction, interactions with wholesalers, methods of price negotiations that involve more ―cond itions,‖ offer selection criteria, etc.) Therefore we have created a separate logistics subsystem (instead of reusing already modeled functions; e.g. price negotiations). Third, this note is devoted to the agent structure and agent interactions and, due to the space limitations, we omit important topics like:forecasts derivation, offer evaluation etc.However, these functions can be encapsulated into modules that can become a part of an appropriate agent. Therefore readers should envision that, for instance, when we write that ―rece ived offers are evaluated,‖then their favorite method of offer evaluationhas been utilized.To proceed, first, we briefly describe our e-commerce system.We follow with assumptions that underline the logistics subsystem and description of new agents that were introduced. Finally, we present the sequence diagram of restocking and use it to discuss in detail how this process will take place in our system.2. System DescriptionOur system is a distributed marketplace in which software agents perform e-commerce functions (see [2] for details, the Use Case diagram in particular). User-Client is represented by the Client Agent (CA). The CA is autonomous and when a purchase order is communicated by the User-Client, it works until either it is completed, or purchase is abandoned. The CA communicates with the Client Information Center (CIC), which facilitates information which e-stores sell which products (yellow-page matchmaking).For each store that sells the requested product, the CA delegates a Buyer Agent (BA) to participate in price negotiations and if successful, possibly attempt at making a pur- chase (successful price negotiations result in a product reservation for a specific time; after which products that have not been purchased are available for sale again).Since multiple BAs representing the same CA can win price negotiations the CA makes the decision if either of available offers is good enough to make a purchase. Buyer Agents can participate in negotiations only if the Gatekeeper Agent (GA) admits them (if they are trusted; e.g. BAs that win price negotiations but do not make a purchase may be barred from subsequent negotiations). The GA represents a given e-store and is created by the Shop Agent (SA). The SA is the central manager and facilitating the selling process it utilizes the GA, and a set of Seller Agents (SeA) that negotiate price with incoming BAs, as well as a Warehouse Agent (WA) that is responsible for inventory and reservation management. Thus far, the WA was responsible for managing product reservations and the inventory. Specifically, (1) before a new price negotiation the WA ―re served‖ a given product—so that if negotiation ended successfully there was an item that could be sold; (2) when a reservation ended in purchase, it adjusted product counters; and (3) when a reservation expired it also adjusted products counters. However, the WA was always envisioned as the ―gat eway‖between the store and suppliers, which is one of the foci of this note.3. Assumptions behind the logistics systemLet us now specify assumptions that underline design of the logistics subsystem:1.Nowadays, except of largest store-chains (e.g. TESCO, WalMart), companiesoutsource transportation activities (considered non-core business activities) to specialists (e.g. UPS, Mayflower). However, we assume here that suppliers are still re sponsible for facilitating transportation. Therefore, we omit transportation related processes and focus only in interactions between e-stores and suppliers2. As a result of (1), transportation costs are assumed to be paid by the supplier and included directly in product price (e.g. discount on delivery costs, will manifest itself in the total price).3. While in the original system auction-based price negotiations were used, here we opted for the simplicity of the FIPA Contract Net Protocol [4]. Therefore, in the logistics subsystem, a single round of negotiations consisting of a call for proposals and evaluation of responses, is used.4. New functions and agentsIn order to perform logistics-related tasks, several new roles were introduced; some of them have been delegated to agents existing in the system, while others warranted adding new agents. Specifically:•demand estimation—to draw information from sales data and/or external premises to predict future sales of products,•warehouse monitoring—to observe supply levels and react in case of a risk ofdropping below values considered sufficient to satisfy estimated demand,•order management—to coordinate issuing orders for goods, to assist inevaluating received offers,•ordering goods—to contact suppliers for their of- fers and to select the best offer,•selling goods—in the system suppliers were also modeled; while goods are acquired without extensive price negotiations, ―someone‖ has to deliver proposals to ordering components,•logistics yellow pages—the role of the ―l og istics CIC‖is very similar to the original CIC ([2]); it has to provide lists of potential suppliers of products; obviously, it is possible for a shop to become a sup- plier for another shop and to suggest that the two CIC s could be joined, but we decided to clearly separate the client-side from the shop and from the supply-side. Another reason for this separation was that while some shops may not be interested in becoming wholesaler, we would have to make changes to the original CIC data structure (e.g. wholesaler—yes/no). Finally, since the logistics subsystem does not involve auctions, the separation is even more warranted.Let us now see how these tasks/roles could be placed in our system. The demandestimation role was attributed to the existing Shop Decision Agent (SDA), responsible for the ―kn owledge managemen t‖functions (e.g. trust management, sales trend data mining, etc.) in the shop.The warehouse monitoring role is already a part of the existing WA. The difference is that now WA becomes a proactive manager of supplies; acting on predictions supplied by the SDA.Fulfillment of the order management role required introduction of the Logistics Agent (LA), which became the ―centra l manager‖ of the logistics subsystem. It is responsible for contacting the logistics CIC for the list of potential suppliers and managing a pool of agents responsible for ordering goods from ―wholesalers.‖ Finally, it collects and manages data related to supplier reliability. This data, in turn, will be one of factors in selecting the supplier.The ordering goods process is facilitated by the Ordering Agent (OA), which is also a new agent. Its task is to issue a call for proposals, collect responses and select the best offer taking into account factors such as: price, delivery time, reliability etc. Let us recall that due to the modularity of agent design ([2]), our system is flexible enough so that any method of selecting an offer can be applied (it can be encapsulated in a module and plugged into the OA).The selling goods role is realized by a very simple Wholesale Agent (WhA). Its role is to respond to CFP’s incoming from OA s.Currently we assume that WhA s receive instructions in what way to generate a stream of responses to the CFPs.Finally, logistics yellow pages are facilitated by the logistics CIC Agent. Its role is to store a complete list of suppliers and products that they sell. Obviously, the logistics CIC uses the original product ontology ([2]), extended by the logistics ontology. When the system is initialized, each WhA registers with the logistics CIC and provides it with a list of products for sale.What was described thus far is summarized in an UML use case diagram presented in Figure 1.Figure 1. Use Case of the logistics subsystem5. Typical Product Restocking ProcessLet us now describe the processes involved in restocking the warehouse. Here, we skip the description of system initialization, and start with the Shop Decision Agent sending a forecast to the Warehouse Agent. The sequence of actions resulting form such a forecast is depicted, as a UML sequence diagram in Figure 2.The SDA communicates the forecast to the WA by sending a FIPA Inform message containing the PredictionDescription (which contains all necessary data such as: product ID, amount of predicted sales, standard deviation of sales, expected purchase price, period for which this forecast is valid, etc.). We assume that the SDA forecasts are of the type: until a new fore- cast, weekly sales are expected to be 45 items of a given product. Forecasts can be issued at specific times (e.g. once a week or once a month) and their frequency de- pends on the information found in data analyzed by the SDA to derive forecast(s).The WA starts by examining current stock of a given product, and if current supplies are sufficient, it sets up to check their levels at the end of the time unit specified in the forecast (i.e. forecasts specified on weekly basis are checked once a week). If stocks are insufficient, the WA utilizes the FIPA Request Protocol (FIPA specification SC00026) and FIPA SL language [4] (used in all agent interactions), to com- municate with the Logistics Agent. The initial message from the WA is the FIPA Request message sent to the LA and it contains OrderRequest action with the Or- derRequestDescription. The OrderRequestDescription contains the necessary information specifying the order to be made: product ID, preferred delivery time, amount and maximumprice. Delivery time and amount are computed based on the current product level, predicted delivery time and an overall inventory strategy.Upon receiving the request, the LA dispatches a query to the logistics CIC to obtain a list of suppliers of a given product. Ensuing conversation conforms to the FIPA Query Protocol, starting with the FIPA Query-Ref message containing the CICQuery action with the Product ID. The logistics CIC responds with the FIPA Inform-Ref message containing the CICResponse with a list (possibly empty) of suppliers. Empty list results in a FIPA Failure message (with OrderRequestResult set to failure) send by the LA to the WA. Similar response is sent when the logistics CIC cannot be contacted.When the non-empty list was received, the LA removes these suppliers that have their reliability value below a certain threshold. Then the LAAgentDescriptions list is formed by supplementing each CICAgentDescription received from the logistics CIC with the reliability information. If a given WhA’s is not known a default trust value is used.After preparing the list, the LA utilizes the FIPA Request Protocol to find a free OA. Busy agents will re- spond with FIPA Refuse messages. If all agents respond in such a way, this process may need to be repeated un- til a free OA is found and responds with the FIPA Agree message. The LA then sends the ordering request to the selected OA and awaits for the result of the ordering pro- cess. LA’s message contains the IssueOrder action with the OrderDescription and the LAAgentDescriptions.After obtaining the request from the LA, the OA engages in the FIPA ContractNet Protocol interactions with WhAs from the list. It sends the FIPA CallForProposal message, containing CFPRequest with OrderDescription to the WhAs. WhAs evaluate the CFP and submit their offers by sending FIPA Propose messages containing the CFP Response actionwith OfferDescription or, if terms contained in the CFP are unacceptable/not interesting, respond using the FIPA Refuse message.Responses must arrive within a timeframe speci- fied by the OA, after which the OA proceeds to evalu- ate them. First, it filters unacceptable offers. Note that it is possible that some WhAs may respond knowingly with proposals that violate some of the conditions and in special circumstances when no better offers were found the OA may need to accept such offers. In the next step, offers are ranked and the winner is determined. Winner issent a FIPA AcceptProposal message containing the ConfirmationRequest action with its offer quoted. The winning WhA must in turn reply with the FIPA Inform messagecontaining Confirmation Response action with the OrderConfirmation which has unique orderID generated by the supplier. This successfully completes the ordering process.The winner can also withdraw the offer by sending a FIPA Failure message. In this case, runner-ups are contacted in an iterative manner. In case when there are no more offers left or there were no offers to begin with, the OA sends a FIPA Failure message to the LA,which, in turn, forwards it to the WA. When the winner confirms the order, the OA sends to the LA a FIPA Inform message containing the InformResult action with the WhA-received Or der Confirmation, thus completing the protocol. At this time the LA sends information to the WA, inside a message of the FIPA Agree type. This performative is used in compliance with the protocol to indicate that the LA is performing the desired task (ordering), but its efforts do not guarantee success (ordering success order success), and thus sending the final response (FIPA Inform) is inappropriate at this stage. Meanwhile the OA returns to the pool of available Ordering Agents.Now the purchase enters the delivery monitoring stage. Here, the LA waits for the delivery from the WhA to be registered with the WA. When a delivery arrives the WA sends (to the LA) a plain FIPA Inform message containing the WADelivery action with the DeliveryDescription, which has supplier’s AgentID and the already mentioned orderId. The LA does not need to respond to this message, but it checks the messages to see if it is currently awaiting a delivery with the given orderId coming from a supplier AgentID. If it finds a match, the ordering process is completed. As a result, the reliability value of supplied AgentID is increased. If a delivery notification does not come within time agreed in the OrderConfirm, actions must be undertaken (recall, that receiving supplies is vital to the e-Shop as its warehouse is likely to run out of stock Those actions are: (1) retry the ordering (sending reminder to the WhA / choosing new WhA), if there is still time, and (2) marking that a retry has been made.If there is still time before the deadline (established by the WA), then order can be retried. If it is the first time an attempt to retry the order is made, a reminder is sent to the WhA. To this end, LA contacts a free OA with a FIPA Request Protocol message with a Reminder action containing AgentID of the WhA and the orderId. The OA accepts the job (the FIPA Agree) and contacts the WhA (also using FIPA Request Protocol), sending it the exact same action. The WhA is expected to reply within a timeframe using either a FIPA Failure (offer is withdrawn) or a FIPA Inform providing new Order Confirmationwith a new delivery time, which is forwarded to the LA unchanged. In the case of an agreement, the LA returns to awaiting delivery, in the case of failure, the LA removes this WhA from the LA Agent Description list and locates an OA to perform entirely new search for a supplier. New search is also ordered if a reminder to the supplier whose delivery we were waiting resulted in a failure. The monitoring stage ends when: (1) delivery is received, or (2) reminder to the supplier was made, but it was refused, while deadline has already passed. Note that we assume that the actual order failure occurs only when the delivery deadline has passed and the reminder failed.This is because it is possible that there is an order delay and goods may arrive late. This information can be obtained from the WhA, and thus the need for the reminder.Figure 2. Restocking process: sequence diagramWhen the monitoring stage ends, the WA is notified about the result by the FIPA Inform or the FIPA Failure message to complete the FIPA Request protocol. The message will contain the OrderRequest action with the OrderRequestResult set appropriately. Furthermore, at this stage the reliability bonuses and/or penalties are calculated and applied. Finally, in the case of a successful order, the WA sends to the SDA a FIPA In-form message containing status information about the re-stocking of the warehouse.6. Concluding remarksIn this note we have discussed the way in which the logistics subsystem is being introduced into our model agent-based e-commerce system. We have presented used UML’s use case and sequence diagrams to formally depict and discuss the most important features of our approach. Due to the lack of space, we have focused our attention on agents and their interactions. The proposed system has been implemented and is in the final testing phase.References[1] C. Bádicá, A.

Specifically:•demand estimation—to draw information from sales data and/or external premises to predict future sales of products,•warehouse monitoring—to observe supply levels and react in case of a risk ofdropping below values considered sufficient to satisfy estimated demand,•order management—to coordinate issuing orders for goods, to assist inevaluating received offers,•ordering goods—to contact suppliers for their of- fers and to select the best offer,•selling goods—in the system suppliers were also modeled; while goods areacquired without extensive price negotiations, ―someone‖ has to deliver proposals to ordering components,•logistics yellow pages—the role of the ―l og istics CIC‖is very similar to the original CIC ([2]); it has to provide lists of potential suppliers of products; obviously, it is possible for a shop to become a sup- plier for another shop and to suggest that the two CIC s could be joined, but we decided to clearly separate the client-side from the shop and from the supply-side. Another reason for this separation was that while some shops may not be interested in becoming wholesaler, we would have to make changes to the original CIC data structure (e.g. wholesaler—yes/no). Finally, since the logistics subsystem does not involve auctions, the separation is even more warranted.Let us now see how these tasks/roles could be placed in our system. The demand estimation role was attributed to the existing Shop Decision Agent (SDA), responsible for the ―kn owledge managemen t‖functions (e.g. trust management, sales trend data mining, etc.) in the shop.The warehouse monitoring role is already a part of the existing WA. The difference is that now WA becomes a proactive manager of supplies; acting on predictions supplied by the SDA.Fulfillment of the order management role required introduction of the Logistics Agent (LA), which became the ―centra l manager‖ of the logistics subsystem. It is responsible for contacting the logistics CIC for the list of potential suppliers and managing a pool of agents responsible for ordering goods from ―wholesalers.‖ Finally, it collects and manages data related to supplier reliability. This data, in turn, will be one of factors in selecting the supplier.The ordering goods process is facilitated by the Ordering Agent (OA), which is also a new agent. Its task is to issue a call for proposals, collect responses and select the best offer taking into account factors such as: price, delivery time, reliability etc. Let us recall that due to the modularity of agent design ([2]), our system is flexible enough so that any method of selecting an offer can be applied (it can be encapsulated in a module and plugged into the OA).The selling goods role is realized by a very simple Wholesale Agent (WhA). Its role is to respond to CFP’s incoming from OA s.Currently we assume that WhA s receive instructions in what way to generate a stream of responses to the CFPs.Finally, logistics yellow pages are facilitated by the logistics CIC Agent. Its role is tostore a complete list of suppliers and products that they sell. Obviously, the logistics CIC uses the original product ontology ([2]), extended by the logistics ontology. When the system is initialized, each WhA registers with the logistics CIC and provides it with a list of products for sale.What was described thus far is summarized in an UML use case diagram presented in Figure 1.Figure 1. Use Case of the logistics subsystem5. Typical Product Restocking ProcessLet us now describe the processes involved in restocking the warehouse. Here, we skip the description of system initialization, and start with the Shop Decision Agent sending a forecast to the Warehouse Agent. The sequence of actions resulting form such a forecast is depicted, as a UML sequence diagram in Figure 2.The SDA communicates the forecast to the WA by sending a FIPA Inform message containing the PredictionDescription (which contains all necessary data such as: product ID, amount of predicted sales, standard deviation of sales, expected purchase price, period for which this forecast is valid, etc.). We assume that the SDA forecasts are of the type: until a new fore- cast, weekly sales are expected to be 45 items of a given product. Forecasts can be issued at specific times (e.g. once a week or once a month) and their frequency de- pends on the information found in data analyzed by the SDA to derive forecast(s).The WA starts by examining current stock of a given product, and if current supplies are sufficient, it sets up to check their levels at the end of the time unit specified in the forecast (i.e. forecasts specified on weekly basis are checked once aweek). If stocks are insufficient, the WA utilizes the FIPA Request Protocol (FIPA specification SC00026) and FIPA SL language [4] (used in all agent interactions), to com- municate with the Logistics Agent. The initial message from the WA is the FIPA Request message sent to the LA and it contains OrderRequest action with the Or- derRequestDescription. The OrderRequestDescription contains the necessary information specifying the order to be made: product ID, preferred delivery time, amount and maximum price. Delivery time and amount are computed based on the current product level, predicted delivery time and an overall inventory strategy.Upon receiving the request, the LA dispatches a query to the logistics CIC to obtain a list of suppliers of a given product. Ensuing conversation conforms to the FIPA Query Protocol, starting with the FIPA Query-Ref message containing the CICQuery action with the Product ID. The logistics CIC responds with the FIPA Inform-Ref message containing the CICResponse with a list (possibly empty) of suppliers. Empty list results in a FIPA Failure message (with OrderRequestResult set to failure) send by the LA to the WA. Similar response is sent when the logistics CIC cannot be contacted.When the non-empty list was received, the LA removes these suppliers that have their reliability value below a certain threshold. Then the LAAgentDescriptions list is formed by supplementing each CICAgentDescription received from the logistics CIC with the reliability information. If a given WhA’s is not known a default trust value is used.After preparing the list, the LA utilizes the FIPA Request Protocol to find a free OA. Busy agents will re- spond with FIPA Refuse messages. If all agents respond in such a way, this process may need to be repeated un- til a free OA is found and responds with the FIPA Agree message. The LA then sends the ordering request to the selected OA and awaits for the result of the ordering pro- cess. LA’s message contains the IssueOrder action with the OrderDescription and the LAAgentDescriptions.After obtaining the request from the LA, the OA engages in the FIPA ContractNet Protocol interactions with WhAs from the list. It sends the FIPA CallForProposal message, containing CFPRequest with OrderDescription to the WhAs. WhAs evaluate the CFP and submit their offers by sending FIPA Propose messages containing the CFP Response actionwith OfferDescription or, if terms contained in the CFP are unacceptable/not interesting, respond using the FIPA Refuse message.Responses must arrive within a timeframe speci- fied by the OA, after which the OA proceeds to evalu- ate them. First, it filters unacceptable offers. Note that it is possible thatsome WhAs may respond knowingly with proposals that violate some of the conditionsand in special circumstances when no better offers were found the OA may need to accept such offers. In the next step, offers are ranked and the winner is determined. Winner issent a FIPA AcceptProposal message containing the ConfirmationRequest action with its offer quoted. The winning WhA must in turn reply with the FIPA Inform message containing Confirmation Response action with the OrderConfirmation which has unique orderID generated by the supplier. This successfully completes the ordering process. The winner can also withdraw the offer by sending a FIPA Failure message. In this case,runner-ups are contacted in an iterative manner. In case when there are no more offers left or there were no offers to begin with, the OA sends a FIPA Failure message to the LA,which, in turn, forwards it to the WA. When the winner confirms the order, the OA sends to the LA a FIPA Inform message containing the InformResult action with the WhA-received Or der Confirmation, thus completing the protocol. At this time the LA sends information to the WA, inside a message of the FIPA Agree type. This performative is used in compliance with the protocol to indicate that the LA is performing the desired task (ordering), but its efforts do not guarantee success (ordering success order success), and thus sending the final response (FIPA Inform) is inappropriate at this stage. Meanwhile the OA returns to the pool of available Ordering Agents.Now the purchase enters the delivery monitoring stage. Here, the LA waits for the delivery from the WhA to be registered with the WA. When a delivery arrives the WA sends (to the LA) a plain FIPA Inform message containing the WADelivery action with the DeliveryDescription, which has supplier’s AgentID and the already mentioned orderId. The LA does not need to respond to this message, but it checks the messages to see if it is currently awaiting a delivery with the given orderId coming from a supplier AgentID. If it finds a match, the ordering process is completed. As a result, the reliability value of supplied AgentID is increased. If a delivery notification does not come within time agreed in the OrderConfirm, actions must be undertaken (recall, that receiving supplies is vital to the e-Shop as its warehouse is likely to run out of stock Those actions are: (1) retry the ordering (sending reminder to the WhA / choosing new WhA), if there is still time, and (2) marking that a retry has been made.If there is still time before the deadline (established by the WA), then order can be retried. If it is the first time an attempt to retry the order is made, a reminder is sent to theWhA. To this end, LA contacts a free OA with a FIPA Request Protocol message with a Reminder action containing AgentID of the WhA and the orderId. The OA accepts the job (the FIPA Agree) and contacts the WhA (also using FIPA Request Protocol), sending it the exact same action. The WhA is expected to reply within a timeframe using either a FIPA Failure (offer is withdrawn) or a FIPA Inform providing new Order Confirmation with a new delivery time, which is forwarded to the LA unchanged. In the case of an agreement, the LA returns to awaiting delivery, in the case of failure, the LA removes this WhA from the LA Agent Description list and locates an OA to perform entirely new search for a supplier. New search is also ordered if a reminder to the supplier whose delivery we were waiting resulted in a failure. The monitoring stage ends when: (1) delivery is received, or (2) reminder to the supplier was made, but it was refused, while deadline has already passed. Note that we assume that the actual order failure occurs only when the delivery deadline has passed and the reminder failed.This is because it is possible that there is an order delay and goods may arrive late. This information can be obtained from the WhA, and thus the need for the reminder.Figure 2. Restocking process: sequence diagramWhen the monitoring stage ends, the WA is notified about the result by the FIPA Inform or the FIPA Failure message to complete the FIPA Request protocol. The message will contain the OrderRequest action with the OrderRequestResult set appropriately. Furthermore, at this stage the reliability bonuses and/or penalties are calculated and applied. Finally, in the case of a successful order, the WA sends to the SDA a FIPA In- form message containing status information about the re-stocking of the warehouse.6. Concluding remarksIn this note we have discussed the way in which the logistics subsystem is being introduced into our model agent-based e-commerce system. We have presented used UML’s use case and sequence diagrams to formally depict and discuss the most important features of our approach. Due to the lack of space, we have focused our attention on agents and their interactions. The proposed system has been implemented and is in the final testing phase.References[1]AgentisSoftware,2007./[2] C. Bádicá, A. Báditá, M. Ganzha, M.
