维基百科(/wiki/Cyber-physical_system)的定义是:A cyber-physical system (CPS) is a system featuring a tight combination of, and coordination between, the system’s computational and physical elements. Today, a pre-cursor generation of cyber-physical systems can be found in areas as diverse as aerospace, automotive, chemical processes, civil infrastructure, energy, healthcare, manufacturing, transportation, entertainment, and consumer appliances. This generation is often referred to as embedded systems. In embedded systems the emphasis tends to be more on the computational elements, and less on an intense link between the computational and physical elements.Unlike more traditional embedded systems, a full-fledged CPS is typically designed as a network of interacting elements with physical input and output instead of as standalone devices.[1] The notion is closely tied to concepts of robotics and sensor networks. The expectation is that in the coming years ongoing advances in science and engineering will improve the link between computational and physical elements, dramatically increasing the adaptability, autonomy, efficiency, functionality, reliability, safety, and usability of cyber-physical systems. The advances will broaden the potential of cyber-physical systems in several dimensions, including: intervention (e.g., collision avoidance); precision (e.g., robotic surgery and nano-level manufacturing); operation in dangerous or inaccessible environments (e.g., search and rescue, firefighting, and deep-sea exploration); coordination (e.g., air traffic control, war fighting); efficiency (e.g., zero-net energy buildings); and augmentation of human capabilities (e.g., healthcare monitoring and delivery)。

MIS is a fresh branch of learning, and it leaped over several territories, and for instance administers scientific knowledge, system science, operational research, statistic along with calculating machine scientific knowledge. Is living on these the branches of learning base, and takes shape that the message is gathered and the process means, thereby take shape the system that the crossbar mingles.1. The Management Information System Summary20 centuries, in the wake of the flourishing development of whole world economy, numerous economists propose the fresh administration theory one by one. Xi Men propose the administration and was dependent on idea to message and decision of strategic importance in the 50’s 20 centuries. The dimension of simultaneous stage is admitted issuing cybernetics, and he thinks that the administration is a control procedure. In 1958, Ger. write the lid: “ the administration shall obtain without delay with the lower cost and exact message, completes the better control “. This particular period, the calculating machine starts being used accountancy work. The data handling term has risen.In 1970, Walter T.Kennevan give administration that has raised the only a short while ago information system term to get off a definition: “ either the cover of the book shape with the discount, is living appropriately time to director, staff member along with the outside world personnel staff supplies the past and now and message that internal forecasting the approaching relevant business reaches such environment, in order to assist they make a strategic de cision”. Is living in this definition to emphasize, yet does not emphasize using the pattern, and mention the calculating machine application in the way of the message support decision of strategic importance.In 1985, admonishing information system originator, title Buddhist nun Su Da university administration professor Gordon B.Davis give the management information system relatively integrated definition, in immediate future “ administer the information system is one use calculating machine software and hardware resources along with data bank man - the engine system.It be able to supply message support business either organization operation, administration or the decision making function. Comprehensive directions of this definition management information system target and meritorious service capacity and component, but also make known the management information system to be living the level that attains at that time.1.1 The Developing History of MISThe management information system is living the most primarily phase iscounting the system, the substance which researched is the regular pattern on face between the incremental data, it what may separate into the data being mutually related and more not being mutually related series, afterwards act as the data conversion to message.The second stage is the data are replaced the system, and it is that the SABRE that the American airline company put up to in the 50’s 20 centuries subscribes to book the bank note system that such type stands for. It possess 1008 bank note booking spots, and may access 600000 traveler keep the minutes and 27000 flight segments record. Its operation is comparatively more complex, and is living whatever one “spot ”wholly to check whether to be the free place up some one flight n umbers. Yet through approximately attending school up to say, it is only a data and replaces the system, for instance it can not let know you with the bank note the selling velocity now when the bank note shall be sell through, thereby takes remedying the step. As a result it also is administer information system rudimentary phase.The third phase is the status reports system, and it may separate into manufacture state speech and service state and make known and research the systems such as status reports and so on. Its type stands for the production control system that is the IBM corporation to the for instance manufacture state speech system. As is known to all, the calculating machine corporation that the IBM corporation is the largest on the world, in 1964 it given birth to middle-sized calculating machine IBM360 and causes the calculating machine level lift a step, yet form that the manufacture administration work. Yet enormously complicatedly dissolve moreover, the calculating machine overtakes 15000 difference components once more, in addition the plant of IBM extends all over the American various places to every one components once more like works an element, and the order of difference possess difference components and the difference element, and have to point out that what element what plant what installation gives birth to, hence not merely giving birth to complexly, fitting, installation and transportation wholly fully complex. Have to there be a manufacture status reports system that takes the calculating machine in order to guarantee being underway successfully of manufacture along with else segment as the base. Hence the same ages IBM establish the systematic AAS of well-developed administration it be able to carry on 450 professional work operations. In 1968, the corporation establishes the communal once more and manufactures informationsystem CMIS and runs and succeeds very much, the past needs 15 weeks work, that system merely may be completed in the way of 3 weeks.It is the data handling system that the status reports system still possess one kind of shape , and that it is used for handles the everyday professional work to make known with manufacture , and stress rests with by the handwork task automation , and lifts the effectiveness with saves the labor power . The data handling system ordinarily can not supply decision of strategic importance message.Last phase is the support systems make a strategic decision, and it is the information system being used for supplementary making a strategic decision. That system may program and the analysis scheme, and goes over key and the error solve a problem. Its proper better person-machine dialogue means, may with not particularlythe personnel staff who have an intimate knowledge of the calculating machine hold conversation. It ordinarily consists of some pattern so as to come into being decision of strategic importance message, yet emphasize comprehensive administration meritorious service capacity.1.2 The Application of Management Information SystemThe management information system is used to the most base work, like dump report form, calculation pay and occurrences in human tubes and so on, and then developing up business financial affairs administrations and inventory control and so on individual event operational control , this pertains to the electron data handling ( EDP Data Processing ) system . When establish the business data bank, thereby possess the calculating machine electric network to attain data sharing queen , the slave system concept is start off , when the implementation the situation as a whole is made program and the design information system ,attained the administration information system phase . In the wake of calculating machine technique progress and the demand adjust the system of people lift further, people emphasize more furthermore administer the information system phase. Progress and people in the wake of the calculating machine technique lift at the demand adjust the system further, people emphasize more furthermore to administer the information system whether back business higher level to lead makes a strategic decision this meritorious service capacity, still more lay special emphasis on the gathering to the external message of business and integrated data storehouse, model library , means storehouse and else artificial intelligence means whether directly to decision of strategic importance person , this is the support system ( DDS ) mission making a strategic decision.There is the part application that few business start MIS inner place the limit of the world at the early days of being living in the 70’s 20 centuries. Up at the moment, MIS is living, and there be the appropriatePopularization rate in every state nation in world, and nearly covered that every profession reaches every department.1.3 The Direction of MIS DevelopmentClose 20 curtains; external grand duke takes charge of having arisen3 kinds of alternations:A. Paying special attention to the administration being emphasized toestablishing MIS’s s ystem, and causing the administration technique headfor the ageing.B. The message is the decision of strategic importance foundation, and MISsupplies the message service in the interest of director at all times.C. Director causes such management program getting in touch with togetherwith the concrete professional work maneuver by means of MIS. not merelybig-and-middle-sized business universally establish MIS some small-sizebusiness also not exceptions of self, universally establish the communaldata network, like the electronic mail and electron data exchange and so on,MIS supplied the well support environment to the application of Intranet’stechnique to speedily developing of INTERNET especially in the past fewyears in the interest of the business.Through international technique development tendency is see, in the 90’s 20 centuries had arisen some kinds of brand-new administration technique.1. Business Processes Rebuild (BPR)A business should value correctly time and produce quality, manufacturing cost and technical service and so on several section administrations, grip at the moment organization and the process compose once more,andcompletes that meritorious service capacity integrationist, operation processization and organization form fluctuation. Shall act as the service veer of middle layer management personnel staff the decision of strategic importance of the director service?2. Intelligentization Decision Support System (IDSS)The intelligentization decision of strategic importance support system was sufficiently consider demand and the work distinguishing feature of business higher level personnel staff.3. Lean Production (LP)Application give birth to on time, comprehensive quality control and parallel project that picked amount is given birth to and so on the technique, the utmost product design cutting down and production cycle, raise produce quality and cuts down the reproduced goods to reserve, and is living in the manufacture promote corps essence, in order to meet the demand that client continuously changes.4. Agile Manufacture (AM)One kind of business administration pattern that possess the vision, such distinguishing feature is workers and staff members’ quality is high, and the organization simplifies and the multi-purpose group effectiveness GAO message loading is agile and answers client requires swiftly.2. The Effect To The Business Administration of MIS DevelopmentThe effect to the business administration of the management information system development is administered the change to business and business administration of information system development and come into being and is coming into being the far-reaching effect with.Decision of strategic importance, particularly strategic decision-making may be assisted by the administration information system, and its good or bad directly affects living and the development up the business. The MIS is impeding the orientation development that the administration means one another unites through quality and ration. This express to utilize the administration in the calculation with the different mathematical model the problem in the quantitative analysis business.The past administer that the problem is difficult to test, but MIS may unite the administration necessaries, and supply the sufficient data, and simulates to produce the term in the interest of the administration.In the wake of the development of MIS, much business sit up the decentralizedmessage concentration to establish the information system ministry of directly under director, and the chief of information system ministry is ordinarily in the interest of assistant manager’s grade. After the authority of business is centralized up high-quality administration personnel staff’s hand, as if causing much sections office work decrease, hence someone prophesy, middle layer management shall vanish. In reality, the reappearance phase employed layer management among the information system queen not merely not to decrease, on the contrary there being the increase a bit.This is for, although the middle layer management personnel staff getting off exonerate out through loaded down with trivial details daily routine, yet needs them to analyses researching work in the way of even more energy, lift further admonishing the decision of strategic importance level. In the wake of the development of MIS, the business continuously adds to the demand of high technique a talented person, but the scarce thing of capability shall be washed out gradually. This compels people by means of study and cultivating, and continuously lifts individual’s quality. In The wake of the news dispatch and electric network and file transmission system development, business staff member is on duty in many being living incomparably either the home. Having caused that corporation save the expenses enormously, the work efficiency obviously moves upward American Rank Zeros corporation the office system on the net, in the interest of the creativity of raise office personnel staff was produced the advantageous term.At the moment many countries are fermenting one kind of more well-developed manufacturing industry strategy, and become quickly manufacturing the business. It completely on the basis of the user requirement organization design together with manufacture, may carry on the large-scale cooperation in the interest of identical produce by means of the business that the flow was shifted the distinct districts, and by means of the once more programming to the machinery with to the resources and the reorganization of personnel staff , constituted a fresh affrication system, and causes that manufacturing cost together with lot nearly have nothing to do with. Quickly manufacturing the business establishes a whole completely new strategy dependence relation against consumer, and is able to arouse the structure of production once more revolution.The management information system is towards the self-adoption and Self-learning orientation development, the decision procedure of imitation man who is be able to be better. Some entrepreneurs of the west vainly hope that consummate MIS is encircles the magic drug to govern the business all kinds of diseases; Yet also someone says, and what it is too many is dependent on the defeat that MIS be able to cause on the administration. It is adaptable each other to comprehend the effect to the business of MIS, and is favor of us to be living in development and the research work, and causes the business organization and administer the better development against MIS of system and administration means , and establish more valid MIS.The Source Of Article: Russ Basiura, Mike Batongbacal管理信息系统管理信息系统就是我们常说的MIS(Management Information System), 在强调管理,强调信息的现代社会中它变得越来越重要、越来越普及。

附录1 外文翻译(原文)Systems Analysis and DesignWorking under control of a stored program, a computer processes data into information. Think about that definition for a minute. Any given computer application involves at least three components: hardware, software, and data. Merely writing a program isn't enough; because the program is but one component in a system.A system is a group of components that work together to accomplish an objective. For example, consider a payroll system. Its objective is paying employees. What components are involved? Each day,employees record their hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer center, where they are read into a payroll program. As it runs, the program accesses data files. Finally, the paychecks are printed and distributed. For the system to work, people, procedures, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.Computer-based systems are developed because people need information. Those people, called users, generally know what is required, but may lack the expertise to obtain it. Technical professionals, such as programmers, have the expertise, but may lack training in the user's field. To complicate matters, users and programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professional who translates user needs into technical terms, thus serving as a bridge between users and technical professionals.Like an engineer or an architect, a systems analyst solves problems by combining solid technical skills with insight, imagination, and a touch of art. Generally, the analyst follows a well-defined, methodical process that includes at least the following steps;1.Problem definition2.Analysis3.Design4.Implementation5.MaintenanceAt the end of each step, results are documented and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early as possible. Perhaps the best way to illustrate the process is through example.Picture a small clothing store that purchases merchandise at wholesale, displays this stock, and sells it to customers at retail. On the one hand, too much stock represents an unnecessary expense. On the other hand, a poor selection discourages shoppers. Ideally, a balance can be achieved: enough, but not too much.Complicating matters is the fact that inventory is constantly changing, with customer purchases depleting stock, and returns and reorders adding to it. [1] The owner would like to track inventory levels and reorder and given item just before the store runs out. For a single item, the task is easy-just count the stock-on-hand. Unfortunately, the store has hundreds of different items, and keeping track of each one is impractical. Perhaps a computer might help.2-1 Problem DefinitionThe first step in the systems analysis and design process is problem definition. The analyst's objective is determining what the user (in this case, the store's owner) needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a "magic box, "and are not concerned with how it works. At this stage, the analyst has no business even thinking about programs, files, and computer hardware, but must communicate with the user on his or her own term.The idea is to ensure that both the user and the analyst are thinking about the same thing-Thus, a clear, written statement expressing the analyst's understanding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money and effort are wasted.Often, following a preliminary problem definition, the analyst performs a feasibility study. The study a brief capsule version of the entire systems analysis and design process, attempts to answer three questions:1.Can the problem be solved?2.Can it be salved in the user's environment?3.Can it be solved at a reasonable cost?If the answer to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, theanalyst can turn to planning and developing a problem solution.2- 2 AnalysisAs analysis begins, the analyst understands the problem. The next step is determining what must be done to solve it. The user knows what must be done 1 during analysis; this knowledge is extracted and formally documented. Most users think in terms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and data elements, yielding a logical system design.Start with the system's basic functions. The key is keeping track of the stock-on-hand for each product in inventory. Inventory changes because customers purchase, exchange, and return products, so the system will have to process customer transactions. The store's owner wants to selectively look at the inventory level for any product in short supply and, if appropriate, order replacement stock, so the system must be able to communicate with management. Finally, following management authorization, the system should generate a reorder ready to send to a supplier.Fig 1Given the system's basic functions, the analyst's next task is gaining a sense of their logical relationship. A good way to start is by describing how data flow between the functions. As the name implies, data flow diagrams are particularly useful for graphically describing these data flows. Four symbols are used (Fig. 1). Data sources and destinations are represented by squares; input data enter the system from a source, and output data flow to a destination. Once in the system, the data are manipulated or change by processes, represented by round-corner rectangles. A process might be a program, a procedure, or anything else that changes or moves data. Data can be held for later processing in data stores, symbolized by open-ended rectangles. A data store might be a disk file, a tape file, a database, written notes, or even a person's memory.Finally, data flow between sources, destinations, processes, end data stores over data flows, which are represented by arrows.Fig 2Figure 2 shows a preliminary data flow diagram for the inventory system. Start with CUSTOMER. Transactions flow from a customer f into the system, where they are handled by Process transaction. A data store, STOCK, holds data on each item in inventory. Process transaction changes the data to reflect the new transaction. Meanwhile, MANAGEMENT accesses the system through Communicate, evaluating the data in STOCK and, if necessary, requesting a reorder. Once, a reorder is authorized. Generate reorder sends necessary data to the SUPPLIER, who ships the items to the store. Note that, because the reorder represents a change in the inventory level of a particular product or products it is handled as a transaction.The data flow diagram describes the logical system. The next step is tracing the data flows. Start with the destination SUPPLIER. Reorders flow to suppliers; for example, the store might want 25 pairs of jeans. To fill the order, the supplier needs the product description and the reorder quantity. Where do these data elements come from? Since they are output by Generate reorder, they must either be Input to or generated by this process. Data flow into Generate reorder for STOCK; thus, product descriptions and reorder quantities must be stored in STOCK.Other data elements, such as the item purchased and the purchase quantity are generated by CUSTOMER. Still others, for example selling price and reorder point, are generated by or needed by MANAGEMENT. The current stock-on-hand for a given item is an example of a data element generated by an algorithm in one of the procedures. Step by step, methodically, the analyst identifies the data elements to be input to .stored by, manipulated by, generated by, or output by the system.To keep track of the data elements, the analyst might list each one in a datadictionary. A simple data dictionary can be set up on index cards, but computerized data dictionaries have become increasingly popular. The data dictionary, a collection of data describing and defining the data, is useful throughout the systems analysis and design process, and is often used to build a database during the implementation stage.The idea of analysis is to define the system's major functions and data elements methodically. Remember that the objective is translating user needs into technical terms. Since the system starts with the user, the first step is defining the user's needs. Users think in terms of functions and data. They do not visualize programs, or files, or hardware .and during this initial, crucial analysis stage it is essential that the analyst think like a user, not like a programmer.Data flow diagrams and data dictionaries are useful tools. They provide a format for recording key information about the proposed system. Also, they jog the analyst's memory) for example, if the analyst doesn't have sufficient information to complete a data dictionary entry, he or she has probably missed something. Perhaps most importantly, the data flow diagram and the data dictionary document the analyst's understanding of the system requirements. By reviewing these documents, the user can correct misunderstandings or oversights. Finally, they represent an excellent starting point the next step, design.2-3 DesignAs we enter the design stage, we know what the system must do, and thus can begin thinking about how to do it. The objective is to develop a strategy for solving the problem. At this stage, we are not interested in writing code or in defining precise data structures; instead, we want to identify, at a black box level, necessary programs, files, procedures, and other components.The data flow diagram defines the system's necessary functions; how might they be implemented? One possibility is writing one program for each process. Another is combining two or more processes in a single program; there are dozens of alternative solutions. Let's focus on one option and document it.A system flowchart uses symbols to represent programs, procedures, hardware devices, and the other components of a physical system (Fig. 3). Our flowchart (.Fig.4) shows that transaction data enter the system through a terminal, are processed by a data collection program, and then are stored on an inventory file. Eventually, the inventory file is processed by a Report and reorder program. Through it, management manipulates the data and authorizes reorders.Fig. 4 on a system flowchart, symbols represent programs, procedures, hardware devices, and the other components of a physical system.Fig 3Look at the system flowchart. It identifies several hardware components, including a computer, a disk drive, a data entry terminal, a printer, and a display terminal. Two programs are needed; Process transaction and Report and reorder. In addition to t he hardware and the programs, we’ll need data structures for the inventory file and for data flaws between the I/O devices and the software. Note that this system flowchart illustrates one possible solution; a good analyst will develop several feasible alternatives before choosing one.Fig 4The flowchart maps the system, highlighting its major physical components. Since the data link the components, the next task is defining the data structures.Consider, for example, the inventory file. It contains all the data elements from the data store STOCK. The data elements are listed in the data dictionary. Using them, the file's data structure can be planned,How should the file be organized? That depends on how it will be accessed. For example, in some applications, data are processed at regular, predictable intervals. Typically, the data are collected over time and processed together, as a batch. If batch processing is acceptable, a sequential file organization is probably best.It is not always possible to wait until a batch of transactions is collected, however. For example, consider an air defense early warning system. If an unidentified aircraft is spotted it must be identified immediately the idea of waiting until 5 _ 00 p.m. because "that's when the air defense program is run" is absurd. Instead, because of the need for quick response, each transaction must be processed as it occurs. Generally such transaction processing systems call for direct access file.Our inventory system has two programs. One processes transactions. A direct access inventory file seems a reasonable choice. The other allows management to study inventory data occasionally; batch processing would certainly do. Should the inventory file be organized sequentially or directly? Faced with such a choice a good analyst considers both options. One possible system might accept transactions and process them as they occur. As an alternative, sales slips might be collected throughout the day and processed as a batch after the store closes. In the first system, the two programs would deal with direct access files; in the second system, they would be linked to sequential files. A program to process direct access data is different from a program to process sequential data. The data drive the system. The choice of a data structure determines the program’s structure. Note that the program is defined and planned in the context of the system.2- 4 ImplementationOnce the system's major components have been identified .we can begin to develop them. Our system includes two programs, several pieces of equipment, and a number of data structures. During implementation, each program is planned and written using the techniques described in Chapter 7. Files are created, and their contents checked. New hardware is purchased, installed, and tested. Additionally, operating procedures are written and evaluated. Once all the component parts are ready, the system is tested. Assuming the user is satisfied, the finished system is released.2- 5 MaintenanceMaintenance begins after the system is released. As people use it, they will suggest minor improvements and enhancements. Occasionally, bugs slip through debug and testing, and removing them is another maintenance task. Finally, conditions change, and a program must be updated; for example, if the government passes a low changing the procedure for collecting income taxes, the payroll program must be modified. Maintenance continues for the life of a system, and its cost can easily match or exceed the original development cost. Good planning, solid documentation, and well-structured programs can help to minimize maintenance cost.附录2 外文翻译(译文)系统的分析与设计在存储程序的控制下,计算机把数据处理成信息。
信息管理与信息系统论文中英文资料外文翻译文献Construction of Network Management Information System of Agricultural Products Supply Chain Based on 3PLsAbstractThe necessity to construct the network management information system of 3PLs agricultural supply chain is analyzed, showing that 3PLs can improve the overall competitive advantage of agricultural supply chain. 3PLs changes the homogeneity management into specialized management of logistics service and achieves the alliance of the subjects at different nodes of agricultural products supply chain. Network management information system structure of agricultural products supply chain based on 3PLs is constructed, including the four layers (the network communication layer, the hardware and software environment layer, the database layer, and the application layer) and 7 function modules (centralized control,transportation process management, material and vehicle scheduling, customer relationship, storage management, customer inquiry, and financial management).Framework for the network management information system of agricultural products supply chain based on 3PLs is put forward. The management of 3PLs mainly includes purchasing management, supplier relationship management, planning management, customer relationship management, storage management and distribution management. Thus, a management system of internal and external integrated agricultural enterprises is obtained. The network management information system of agricultural products supply chain based on 3PLs has realized the effective sharing of enterprise information of agricultural products supply chain at different nodes, establishing a long-term partnership revolving around the 3PLs core enterprise, as well as a supply chain with stable relationship based on the supply chain network system, so as to improve the circulation efficiency of agricultural products, and to explore the sales market for agricultural products.Key words3PLs (third party logistics),Agricultural products supply chain, Network management information system, China3PLs means that production enterprises entrust the logistics activity to the professional logistics service firms in order to concentrate efforts on core business, to keep close contact with logistics enterprise through information system, and to achieve a logistics operation and management mode with full control in logistics. According to the 3PLs requirements forinformation technology, supply chain management information system based on 3PLs is a supply chain management mode with 3PLs enterprises as the core, using EDI technology, GIS/GPS system, B/S mode and other technologies. Integration, processing and application of 3PLs enterprises in supply chain management information system are fully applied in order to reduce the cost of logistics and to improve the service level of logistics.At present, management information technology in China is just at the initial stage. The existing management information system offers insufficient information for the 3PLs enterprises which are engaged in the circulation of agricultural products.Besides, its construction of logistics data processing system is imperfect, having not realized the truly professional 3PLs enterprises for the circulation of agricultural products with information technology. At the same time, 3PLs enterprise for agricultural products has just started in China. And logistics applied in the agricultural supply chain with 3PLs enterprise as the core is time-consuming, inefficient and low-level, which can hardly meet the needs of the rapid development of rural market and social productive forces. Therefore, it is particularly important and urgent to construct a management information system for agricultural products supply chain under the current Internet environment. Problems in the management of the supply chain of agricultural products are analyzed, and a network management information system of agricultural products supply chain based on 3PLs is constructed in order to offer references for the information management in the supply chain of agricultural products in China.1 Necessity of constructing the network management information system of agricultural products supply chain based on 3PLsAgricultural products are seasonal, perishable and vulnerable. With the improvement of income level,consumers have increasingly high requirements for the diversification, personalization, just-in-time nature, and environment protection of agricultural products, which requires faster, more professional,and better organized logistics. At the same time, supply chain of agricultural products has the characteristics of the special purpose of funds, the uncertainty of market, and the unbalanced development of market. Thus, the support of supply chain management information system is needed during the circulation of agricultural products. Construction of market integration,as well as the integration of production, supply and marketing,urgently needs a new management information system of agricultural products, as well as an accompanying legal support system, in order to reduce the cost and to increase the profit for agricultural enterprises. And the application of 3PLs in the supply chain of agricultural products can solve this problem.Therefore, we should give full play to the central hub function of 3PLs enterprises in agricultural products supply chain, increase the input in the informationization of agricultural products supply chain, and promote the construction of logistics operation system and management information system.1 .1 Improving the overall competitive advantage of agricultural products supply chain by 3PLs3PLs is a new logistics organizational form established by modern information technology, as well as a kind of complementary and win-win strategic alliance by signing contract with the party being served. Taking 3PLs as the professional and core enterprise in the production and circulation of agricultural products can help to realize resource consolidation of the construction and organization of the whole supply chain of agricultural products. The specialization of raw materials and the service for product distribution have greatly improved the logistics efficiency of traditional enterprise. At the same time, construction of the management information system ofagricultural products supply chain based on 3PLs has made up for the shortage of information in agricultural market, has improved the efficiency of the flow of agricultural products, has connected all the links in the supply chain into an organic whole in an reasonable and effective way,and has enhanced the overall competitive advantage and economic benefits. 3PLs platform has greatly brought down the production and circulation processes of traditional agricultural enterprises, and has reduced the costs in raw material procurement and product distribution, so as to better adapt to the changes in market demand, to realize the rational distribution of resources, and to improve the overall competitiveness of the supply chain of agricultural products.1 .2 Changing the homogeneity management to specialized operation of logistics service by 3PLsDue to the characteristics of agricultural products, market requirement for logistics varies widely. Since traditional enterprises try to obtain the competitive advantage, there is fierce market competition in commodity circulation. Therefore, behavior of logistics market shows the characteristics of homogeneity and the profit is getting lower and lower. In order to seize the customer, some enterprises even take a loss. 3PLs enterprises share business risk with partners and carry out operation according to the items number, time and cost of customer by integration and utilization of resources. As a means of the supply chain integration of agricultural products, specialized operation of 3PLs can help the stakeholders of supply chain to obtain more demand information of agricultural products, and can reduce the circulation cost of agricultural products.1 .3 Alliance of the subjects in supply chain nodes of agricultural products by 3PLs3PLs stresses the relationship of “mutual complementarity, benefit sharing, information sharing” among the stakeholders in different nodes of supply chain. Development of the agricultural producer, supplier and retailer is limited if they rely only on their own resources. 3PLs enters into the outside service market, integrates the resources through the way of strategic alliances, ensures that the subject focuses its attention on core business, reduces the cost by scale effect, enhances the anti-risk strength, and helps to achieve quick response to market demand by information sharing.At the same time, contract-0riented 3PLs enterprises unify the interests of all subjects in supply chain of agricultural products, emphasize the strategic partnership of both parties,and alleviate market competition of related industries in agricultural markets. Subjects in both downstream and upstream of the supply chain share information and establish long-term partnership with 3PLs enterprises as the core.2 Construction of the network management information system of agricultural supply chain based on 3PLs2.1 Construction of structural system3PLs platform is used to offer network communications and system services to the subjects in agricultural supply chain. Fig. 1 illustrates the structural system of network management information system of agricultural supply chain based on 3PLs.Fig.1 Structural system of network management information system of agricultural supplychain based on 3PLsFig. 1 illustrates that the basic hardware of the system is combined by the network transmission media and network equipment, that is the network communication layer. Hardware facilities, corresponding system software, operation system and netmanager software together constitute the software and hardware environment layer.This layer provides necessary software and hardware facilities for 3PLs enterprises during the data storage and management of agricultural products. Database layer is responsible for the management of data source in agricultural information resources and network systems, and offers data integration to the application layer. 3PLs standard system includes the overall standard, network infrastructure standard, application support standard, application standard, information security standard, and management standard. Safety system of 3PLs includes the security management, security infrastructure, and security service.This system is composed of 7 function modules, such as the centralized control module, transportation process management module, material and vehicle scheduling module, customer relationship module, storage management module, customer query module, and financial management module(Fig. 2),the function of which is to ensure the information fluency and system security of 3PLs enterprises during the operation and integration of resources. These modules have improved the service module of different nodes in agricultural supply chain and have reduced the operation risk of system, so that the system becomes more structured, perfect, and rational.2.2 Framework of management systemBased on the existing research result,the business and module of modern logistics management,and the management information systems,Fig.3 reports the management system of internal and external integrated agricultural enterprises according to the circulation of agricultural products from the manufacturer,supplier,and retail terminal to the consumer.Fig.2 Function modules of 3PLs network management information systemFig.3 The management system of internal and external integrated agricultural enterprises Fig.3 shows the framework of network management information system of agricultural supply chain based on 3PLs. The whole system, running under an open 3PLs, is formed by four layers of network communication layer, software and hardware environment layer, database layer and application layer. In the application layer, 3PLs, as the core of management information system of agricultural supply chain, plays the role of information processing center. It mainly manages the plan, inventory, and other subsystems, supervises subsystem through supplier relationship, conducts information interaction with procurement management subsystem and the supplier, and carries out information interaction with the supplier, producer and consumer through customer relationship management subsystem and sales management subsystem. Besides, 3PLs is also responsible for logistics management and control through the distribution management subsystem. Management of 3PLs mainly includes the 7 modules of purchasing management, supplier relationship management, planning management, customer relationship management, sales management, inventory management and distribution management. Through the effectiveintegration and coordination between 3PLs and the business with partner at the downstream and upstream of agricultural supplier chain, management system of internal and external integrated agricultural enterprises is formed using the logistics information system to realize the integration of logistics and information flow.In general,3PLs enterprise is still in the initial stage in China. Management information system of agricultural supply chain is not perfect, which can not meet the current needs of the rapid development and agricultural products circulation in rural China. Thus, there is an urgent need to build a new mode of agricultural logistics, so as to reduce the process of sales turnover, to lower the production cost of 3PLs enterprises, to improve the circulation efficiency of agricultural products, and to expand the sales market of agricultural products.3 ConclusionDeveloping modern 3PLs is an inevitable trend of market development. Design and development of management information system based on 3PLs can bring spillover benefits to the producer, supplier and retailer of agricultural products.Under the current Internet environment, management information system of agricultural supply chain based on 3PLs must be established based on the specific characteristics of operation mode and the actual business situation of 3PLs enterprises, so as to establish a management information system suitable for a given enterprise. From the perspective of overall integration of resources, the network management information system of agricultural supply chain based on 3PLs established has connected the interests of different nodes in agricultural supply chain into an organic whole, has effectively eliminated the barriers to information flow, and has increased the profits of agriculture-related enterprises and farmers. At the same time, according to the characteristics of agricultural enterprises in China, a rational agricultural products logistics mode of internal and external integrated agricultural enterprise is established, which offers a reference for the management of agricultural supply chain in China.基于第三方物流的农产品供应链网络管理信息系统的建设摘要本文对构建网络农业第三方物流供应链管理信息系统的必要性进行了分析,表明第三方物流可以提高农产品供应链的整体竞争优势。
PLM、ERP. APS. MESA种信息系统的数据集成!导读本文就PLM、ERP、APS、MES各自功能和相互之间需要通信的基础数据进行探讨,分析几个系统集成的方法,供企业进行信息化时借鉴。
01前言技术的发展日新月异,企业要增强竞争力,在市场竞争中立于不败之地,采用先进技术武装自己是必由之路。
近30年,对社会影响最大的技术进步当属信息技术,信息技术的进步改变着我们的日常生活,也改变着企业的管理方式。
现在我们在企业内办公,主要的工作都是通过电脑完成的,当然现在智能手机也能完成某些原来需要通过电脑完成的工作,但信息系统的主要功能还是通过电脑端完成的。
电脑只是硬件,具体的功能还必须通过软件来实现,例如Word, Excel等都是常用软件。
稍有规模的企业都是由多个部门组成的,部门之间的信息交流就需要更复杂的信息系统来实现,PLM(产品生命周期管理),ERP(^^SS^0J), APS(高级计划与排匐,MESGH遭执行系统)是不同的信息系统,它们功能不同,但使用数据存在交叉重叠。
如果这些系统之间没有集成,各自的系统所需数据需要多次录入,增加了信息维护工作量和出错机会,每个系统都是一座信息孤岛。
如果是成立多年的企业,他们的信息化路径一般是,从财务系统和CAD画图开始,然后又过渡到进销存,之后进行生产环节的信息化。
除非新成立的企业,信息化工作可以全盘展开考虑。
已经存在的企业,面临的局面都是已经有些信息系统,如果继续提升信息化水平,必须结合当前的状况。
必须考虑未来信息系统与现在信息系统的集成。
〃中国制造2025”加深了中国制造企业对PLM的认知度。
一些企业开始认识到产品创新的重要性。
企业通过PLM对产品的整个生命周期进行管理,可以加速产品的创新迭代,让产品更多增值,PLM技术就是为适应企业的发展的要求而产生的。
凡事预则立,不预则废。
对信息系统规划也是一样,信息规划者既要看当前企业需求,也要考虑未来增加信息系统时,不同信息系统之间的衔卿信息通信。

Management Information SystemIt is the MIS(Management Information System) that we constantly say that the management information system , and is living to emphasize the administration , and emphasizes that it changes into more and more significantly and more and more is universalized in the contemporary community of message . MIS is a fresh branch of learning, and it leaped over several territories, and for instance administers scientific knowledge, system science, operational research, statistic along with calculating machine scientific knowledge. Is living on these the branches of learning base, and takes shape that the message is gathered and the process means, thereby take shape the system that the crossbar mingles.1. The Management Information System Summary20 centuries, in the wake of the flourishing development of whole world economy, numerous economists propose the fresh administration theory one by one. Xi Men propose the administration and was dependent on idea to message and decision of strategic importance in the 50’s 20 centuries. The dimension of simultaneous stage is admitted issuing cybernetics, and he thinks that the administration is a control procedure. In 1958, Ger. write the lid: “ the administration shall obtain without delay with the lower cost and exact message, completes the better control ”. This particular period, the calculating machine starts being used accountancy work. The data handling term has risen.In 1970, Walter T.Kennevan give administration that has raised the only a short while ago information system term to get off a definition: “ either the cover of the book shape with the discount, is living appropriately time to director, staff member along with the outside world personnel staff supplies the past and now and message that internal forecasting the approaching relevant business reaches such environment, in order to assist they make a strategic decision”. Is living in this definition to emphasize, yet does not emphasize using the pattern, and mention the calculating machine application in the way of the message support decision of strategic importance.In 1985, admonishing information system originator, title Buddhist nun Su Da university administration professor Gordon B.Davis give the management information system relatively integrated definition, in immediate future “ administer the information system is one use calculating machine software and hardware resources along with data bank man - the engine system. It be able to supply message support business either organization operation, administration or the decision making function”. Comprehensive directions of this definition management information system target and meritorious service capacity and component, but also make known the management information system to be living the level that attains at that time.1.1 The Developing History of MISThe management information system is living the most primarily phase is counting the system, the substance which researched is the regular pattern on face between the incremental data, it what may separate into the data being mutually related and more not being mutually relatedseries, afterwards act as the data conversion to message.The second stage is the data are replaced the system, and it is that the SABRE that the Amer ican airline company put up to in the 50’s 20 centuries subscribes to book the bank note system that such type stands for. It possess 1008 bank note booking spots, and may access 600000 traveler keep the minutes and 27000 flight segments record. Its operation is comparatively more complex, and is living whatever one “spot ”wholly to check whether to be the free place up some one flight numbers. Yet through approximately attending school up to say, it is only a data and replaces the system, for instance it can not let know you with the bank note the selling velocity now when the bank note shall be sell through, thereby takes remedying the step. As a result it also is administer information system rudimentary phase.The third phase is the status reports system, and it may separate into manufacture state speech and service state and make known and research the systems such as status reports and so on. Its type stands for the production control system that is the IBM corporation to the for instance manufacture state speech system. As is known to all, the calculating machine corporation that the IBM corporation is the largest on the world, in 1964 it given birth to middle-sized calculating machine IBM360 and causes the calculating machine level lift a step, yet form that the manufacture administration work. Yet enormously complicatedly dissolve moreover, the calculating machine overtakes 15000 difference components once more, in addition the plant of IBM extends all over the American various places to every one components once more like works an element, and the order of difference possess difference components and the difference element, and have to point out that what element what plant what installation gives birth to, hence not merely giving birth to complexly, fitting, installation and transportation wholly fully complex. Have to there be a manufacture status reports system that takes the calculating machine in order to guarantee being underway successfully of manufacture along with else segment as the base. Hence the same ages IBM establish the systematic AAS of well-developed administration it be able to carry on 450 professional work operations. In 1968, the corporation establishes the communal once more and manufactures information system CMIS and runs and succeeds very much, the past needs 15 weeks work, that system merely may be completed in the way of 3 weeks. It is the data handling system that the status reports system still possess one kind of shape , and that it is used for handles the everyday professional work to make known with manufacture , and stress rests with by the handwork task automation , and lifts the effectiveness with saves the labor power . The data handling system ordinarily can not supply decision of strategic importance message.Last phase is the support systems make a strategic decision, and it is the information system being used for supplementary making a strategic decision. That system may program and the analysis scheme, and goes over key and the error solve a problem. Its proper better person-machine dialogue means, may with not particularly the personnel staff who have an intimate knowledge of the calculating machine hold conversation. It ordinarily consists of some pattern so as to come into being decision of strategic importance message, yet emphasizecomprehensive administration meritorious service capacity.1.2 The Application of Management Information SystemThe management information system is used to the most base work, like dump report form, calculation pay and occurrences in human tubes and so on, and then developing up business financial affairs administrations and inventory control and so on individual event operational control , this pertains to the electron data handling ( EDP Data Processing ) system . When establish the business data bank, thereby possess the calculating machine electric network to attain data sharing queen , the slave system concept is start off , when the implementation the situation as a whole is made program and the design information system ,attained the administration information system phase . In the wake of calculating machine technique progress and the demand adjust the system of people lift further, people emphasize more furthermore administer the information system phase. Progress and people in the wake of the calculating machine technique lift at the demand adjust the system further, people emphasize more furthermore to administer the information system whether back business higher level to lead makes a strategic decision this meritorious service capacity, still more lay special emphasis on the gathering to the external message of business and integrated data storehouse, model library , means storehouse and else artificial intelligence means whether directly to decision of strategic importance person , this is the support system ( DDS ) mission making a strategic decision.There is the part application that few business start MIS inner place the limit of the world at the early days of being living in the 70’s 20 centuries. Up at the moment, MIS is living, and there be the appropriate popularization rate in every state nation in world, and nearly covered that every profession reaches every department.1.3 The Direction of MIS DevelopmentClose 20 curtains; external grand duke takes charge of having arisen3 kinds of alternations:A. Paying special attention to the administration being emphasized to establishing MIS’s system, and causing the administration technique head for the ageing.B. The message is the decision of strategic importance foundation, and MIS supplies the message service in the interest of director at all times.C. Director causes such management program getting in touch with together with the concrete professional work maneuver by means of MIS. not merely big-and-middle-sized business universally establish MIS some small-size business also not exceptions of self, universally establish the communal data network, like the electronic mail and electron data exchange and so on, MIS supplied the well support environment to the ap plication of Intranet’s technique to speedily developing of INTERNET especially in the past few years in the interest of the business.Through international technique development tendency is see, in the 90’s 20 centuries had arisen some kinds of brand-new administration technique.1. Business Processes Rebuild (BPR)A business should value correctly time and produce quality, manufacturing cost and technicalservice and so on several section administrations, grip at the moment organization and the process compose once more,andcompletes that meritorious service capacity integrationist, operation processization and organization form fluctuation.2. Intelligentization Decision Support System (IDSS)The intelligentization decision of strategic importance support system was sufficiently consider demand and the work distinguishing feature of business higher level personnel staff.3. Lean Production (LP)Application give birth to on time, comprehensive quality control and parallel project that picked amount is given birth to and so on the technique, the utmost product design cutting down and production cycle, raise produce quality and cuts down the reproduced goods to reserve, and is living in the manufacture promote corps essence, in order to meet the demand that client continuously changes.4. Agile Manufacture (AM)One kind of business administration pattern that possess the vision, such distinguishing feature is workers and staff members’ quality is high, and the organization simplifies and the multi-purpose group effectiveness GAO message loading is agile and answers client requires swiftly.2.The Effect To The Business Administration of MIS DevelopmentThe effect to the business administration of the management information system development is administered the change to business and business administration of information system development and come into being and is coming into being the far-reaching effect with. Decision of strategic importance, particularly strategic decision-making may be assisted by the administration information system, and its good or bad directly affects living and the development up the business. The MIS is impeding the orientation development that the administration means one another unites through quality and ration. This express to utilize the administration in the calculation with the different mathematical model the problem in the quantitative analysis business.The past administer that the problem is difficult to test, but MIS may unite the administration necessaries, and supply the sufficient data, and simulates to produce the term in the interest of the administration.In the wake of the development of MIS, much business sit up the decentralized message concentration to establish the information system ministry of directly under director, and the chief of information system ministry is ordinarily in the interest of assistant manager’s grade. After the authority of business is centralized up high-quality administration personnel staff’s hand, as if causing much sections office work decrease, hence someone prophesy, middle layer management shall vanish. In reality, the reappearance phase employed layer management among the information system queen not merely not to decrease, on the contrary there being the increase a bit. This is for, although the middle layer management personnel staff getting off exonerate out through loaded down with trivial details daily routine, yet needs them to analyses researchingwork in the way of even more energy, lift further admonishing the decision of strategic importance level. In the wake of the development of MIS, the business continuously adds to the demand of high technique a talented person, but the scarce thing of capability shall be washed out gradually. This compels people by means of study and cultivating, and continuously lifts individual’s quality. In the wake of the news dispatch and electric network and file transmission system development, business staff member is on duty in many being living incomparably either the home. Having caused that corporation save the expenses enormously, the work efficiency obviously moves upward American Rank Zeros corporation the office system on the net, in the interest of the creativity of raise office personnel staff was produced the advantageous term.At the moment many countries are fermenting one kind of more well-developed manufacturing industry strategy, and become quickly manufacturing the business. It completely on the basis of the user requirement organization design together with manufacture, may carry on the large-scale cooperation in the interest of identical produce by means of the business that the flow was shifted the distinct districts, and by means of the once more programming to the machinery with to the resources and the reorganization of personnel staff , constituted a fresh affrication system, and causes that manufacturing cost together with lot nearly have nothing to do with. Quickly manufacturing the business establishes a whole completely new strategy dependence relation against consumer, and is able to arouse the structure of production once more revolution.The management information system is towards the self-adoption and Self-learning orientation development, the decision procedure of imitation man who is be able to be better. Some entrepreneurs of the west vainly hope that consummate MIS is encircles the magic drug to govern the business all kinds of diseases; Yet also someone says, and what it is too many is dependent on the defeat that MIS be able to cause on the administration. It is adaptable each other to comprehend the effect to the business of MIS, and is favor of us to be living in development and the research work, and causes the business organization and administer the better development against MIS of system and administration means , and establish more valid MIS.管理信息系统管理信息系统就是我们常说的MIS(Management Information System),它立足于强调管理,强调信息社会中信息变得越来越重要。

信息安全
信息的威胁和其减少方法
信息系统存在一些潜在的威胁和它们所持有的数据。复杂的方面中
最大的威胁来自合法用户
信息和开发商。纯粹偶然,一个使用者可能进入不正确的数据或者删除重要信息。一个设计者可
能误解一个重要的功能和一个系统将会产生的错误结果。一个无辜的编程错误可能导致错误的或
销毁数据。对于一个脆弱的系统来说一个小的改变会导致全部系统的一连串失败。
我们能发现和保护一些这样的问题通过仔细的设计,测试,训练,和备份版本。然而,现代的信
息系统是极其复杂的。我们并不能保证它们将工作的一直很好。另外,经受物理威胁不可避免的:
飓风,地震,洪水等等。通常,最好建立我们能做的是建立应急计划,使公司能够尽可能快的恢
复。最重要的方面是一些灾害计划去保持足够的备份。公司能够提供各种的连续的信息系统支持
用详细的计划,组织,和足够的金钱。
第二类问题是由技术变化所带来的,罪犯也如此。今天,只有不顾一切的人才会用枪去抢劫银行。
这样被抓的可能性会很高,和一些数量的钱被偷的可能性低。并不是说我们希望鼓励任何人成为
盗贼,但是计算机为偷盗大量钱财提供了更为容易的途径。
确定计算机安全的潜在威胁是很重要的。一些工具是很容易使用它对于初学者使用互联网来攻击
公司,但是到目前为止最大的问题还是公司的内部人员和病毒。
灾难
幸运的是火灾,洪水,飓风,和其他的自然灾难并不是经常的发生。但是,当灾难袭击公司数据
中心的时候,它可能会毁灭公司。没有有效的准备工作,数据中心丢失数据的将关闭运行。多长
时间已过现代化的公司能不通过事务处理来进行拯救。
如今,这里有些个计划方法和灾难恢复。一个通用的方式与一个灾难恢复服务提供商签约。服务
提供商像SunGard它是使用他的商用恢复设备和提供不同的支持水平的各种费用。一个普通支持
水平被称为热站,他是由一个完全配置的计算机中心组成。特殊电脑设备是已完成安装和随时为
使用者使用。当MIS员工声明了一个灾难,他们安装备份磁带在热站电脑上和使用在线电信去
每日重复的运行。还有另外其他的选择被称为冷站,他将提供完全的电脑空间功能不用电脑设备。
如果一个灾难发生,或者电脑或者灾难恢复服务提供商能提供可能的设备去运输给冷站。然而,
他们可能延迟服务时期在一个新的数据将被运行。因此,一个冷站通常被用来和热站进行连接。
对于电脑运行绝对不可以被中断,一些公司利用一个后台电脑对不断去维持一个完整版的备
份日常运行。全部的数据是在相同的地点保持同步。如果一个设备的问题上升的话,第二个将会
自动的接管。特殊的公司现在提供他的数据反映设备。外部公司是发送所有你的数据的备份来作
为它的生成。公司做复制备份并提供一些及时的实质性的更新服务如果某些干扰你的主电脑的时
候。
雇员和顾问
雇员是任何一个公司的核心。公司功能和成功是通过信任他们的员工。虽然大多数的员工是
诚实和勤劳的,但是他们总是碰巧出现一个员工总是用公司的知识,经验,和信赖去误用资源。
它可能很难确定那些可能引起公司破坏的人员。一些公司现在用物理测试,检查背景,和一
些测试来表明其潜在的问题。更多的公司担心他们的员工停止雇佣关系。当员工离开时遵循企业
具体步骤,特别小心的去移动雇员进入公司的电脑。
一个更加复杂的问题在MIS雇员中提升。程序和分析必须被信任。没有它们,将不会有软
件。然而,它最好是使用者的程序不是程序员。公司强制的去分离一些职责在全体程序员和使用
者之间。考虑当一个银行出纳员职责是出纳员使用电脑程序可能发生的。审计事务处理系统是一
个非常重要的工作对于审计员。
不讲道德的程序员也知道在他们的软件里也包括“定时炸弹”。当软件运行的时候,它能检测隐藏
文件为了加密文字。如果程序员离开公司,这些加密文档将不会改变,当程序没有发现正确的,
它会开始查询文件。在大型项目上,这些炸弹有可能去准确(直到它们离去)。保持好的备份可
能通常会轻视破坏。最为一个相关的注解,一个软件工程推动相关采纳一系列新的法律(UCITA),
如果一个软件公司有争论对于一个商业使用它的软件使其更加的合法化去关闭这个定时炸弹。
另一个危险领域是程序者可能包括一个陷阱关卡或者秘密指令能允许它们去进入软件即使他们
离开公司。有时它们的陷阱门安装简单,使程序员能够迅速的做出正确。重要的一点是能确保他
们移动当系统能永久的安装。
一个有趣的分类来获取数据的威胁来自疏忽而不是故意的行动通过用户。例如,雇员可能偶然删
除数据。或者,移除风险,磁带,或甚至笔记本通过有吸引力的领域有时可能毁坏文件。在这些
事件中,最好的确信有完整的备份能力。更多的复杂问题提升当笔记本丢失或者被盗。根据数据
在设备上的存储,一个文件通常保留全部电脑的密码。一些笔记本提供密码和数据脚本去缩小他
们的问题。其他的一个问题属于这一类是一个警告要小心你如何处理旧磁带,风险,和电脑设备。
商业运行相似的风险当他们发送他们电脑设备去修理。
通常来说,最好的将问题最小化的方法是从员工源于典型的管理技术。雇佣员工谨慎,对待员工
公正,有明确的工作分工,使用团队作业,和保持经常性检查他们的工作。顾问提出一种类似员
工的潜在问题。然而,顾问趋向一种被雇用在短暂时间内,因此一些公司了解他们的程度要少于
正规的员工。顾问通常被用来做特殊的工作,因此他们不可能有一些内部的雇员能完全的监视他
们的工作。
商业伙伴
像电脑在各个商业方面传遍并贯穿,一些公司分享他们的数据。例如,通用汽车要求他们的供应
商提供所有的电子的信息。EDI意思是商业信息被迅速的处理加工和少数的错误。在一些事件中,
这个问题意味着通用给其他的公司考虑去进入通用的电脑和亦然。例如,如果通用考虑去提高产
量,管理者可能想去检查他们的供应商产量表以便去确认供应商能提供需要的份额。去做它的电
子,通用需要进入供应商的电脑。商业合作的今天,你必须信任你的伙伴。然而,你限制了你评
估的能力在所有他们的雇员中。
合作伙伴的问题变得越来越重要了在互联网软件的世界里。逐渐增加,公司提供互联网服务在软
件和你的数据方面都会存有一个服务提供商的站点。NetLedger就是一个很好的例子,它是一个
应用服务提供者(ASP)是建立专业和运行站点因此你不用聘请专家,储存网上的处境意味着它
对于你的员工进入网站很容易去获得。并且你可能开始很小和这种没有争论的可能性将会增加。
病毒
办公软件目前存在重点的缺陷因为为了应用程序出现一种支持大型项目语言工具叫做Visual
Basic.这种语言有强大的特性使管理信息部门和其他的软件达到去做一些自动化的任务—例如
同步日期和多种设备相关联的列表。问题是项目语言有可能被利用去创造项目去盗用或破坏你的
数据。
这些程序可能被隐藏在一个文件内,放映幻灯片,数据库,或者电子邮件信息。一个特别危险的
威胁来自于一些形式的软件程序被叫做病毒。一个电脑病毒是一个小的程序被隐藏在一些附加程
序的内部用电子邮件信息发送。如果你打开一个附件,大型的程序运行和病毒有做两个事情的倾
向:(1)它发送自身给每一个你的电话簿以你的名义,并且(2)他附加它自己给其他的文件在
你的电脑。同样,恶劣的病毒还会删除你的文件,或者发送你的文件给网站服务者。有些作者做
一些个区别并叫这个程序为蠕虫如果他简单的复制它自己但不会出现标志性的错误。
一个病毒可能被拾起通过多种的途径,但是电子邮件附件是非常流行的方式。杀毒软件将会查杀
你的电脑已知的病毒。即使如此,公司仍然会有病毒的问题经历。病毒和蠕虫是最通用的正面攻
击公司在当今。一旦一种病毒被定义了以后杀毒软件能帮助清理文件。但是它被证明不是很有效
去停止攻击—尤其是一些新的病毒在每天都被创造着。在1999年,估计软件病毒成本少量的在
八千万美元之下在单独美国一个来说。
今天,他是很容易去创造一个病毒—很容易发现一个病毒软件装备在网上,做一些改变,并且发
送给某个人。你将需要一点小的技术。当然了,它是一种合法的创造和降低病毒并且具有破坏性
的软件。
阻止病毒最好的方式是避免下载软件设备来自互联网和不要打开一些附件在电子邮件上的脚本
—即使它们出现来自你的朋友。谨慎,因为出现在一些图片上的附件实际上是一种病毒脚本。经
销商开始从事于电子邮件拦截能阻止附件脚本,但是它们趋向于压制和阻止对于有用的文件。
总而言之,对于病毒最重要的步骤是确保你总有最近的备份文件。其次即使一个病毒删除你的文
件,你能恢复数据,下载和杀毒软件包和移除病毒,它将花费你的时间,但是至少你将储存你的
数据。
