基于分解的算法开发出来并与增强策略结合起来解决大规模优化实例.该算法的效率已被测试,实验结果也已经发表。

本文的理论贡献在于文中提出的模型和基于分解的精确算法的开发.另外，基于我们的算法设计出的基于不确定性整合的生产线的产出率会更高，因此也更具有实际意义。

此外,这是一个在装配线平衡问题上的开创性工作,并应该作为一个决策支持系统的基础。

关键字：装配线平衡；不确定性; 鲁棒优化；组合优化；精确算法1.简介装配线就是包括一系列在车间中进行连续操作的生产系统。

零部件依次向下移动直到完工。

它们通常被使用在高效地生产大量地标准件的工业行业之中。

在这方面，建模和解决生产线平衡问题也鉴于工业对于效率的追求变得日益重要。

生产线平衡处理的是分配作业到工作站来优化一些预定义的目标函数。

那些定义操作顺序的优先关系都是要被考虑的,同时也要对能力或基于成本的目标函数进行优化。

就生产（绍尔，1999）产品型号的数量来说，装配线可分为三类：单一模型（SALBP）,混合模型(MALBP）和多模式（MMALBP）。

上个世纪60年代，韩国电影迅速崛起，然而很快便陷入停滞状态,直到90年代以后，韩国电影又重新进入繁盛时期。

在这个时期，韩国电影在数量上并没有大幅的增长，但多部电影的观影人数达到了上千万人次。

1996年，韩国本土电影的市场占有量只有23.1%。

但是到了1998年，市场占有量增长到35。

8%，到2001年更是达到了50%。

虽然从1996年开始，韩国电影一直处在不断上升的过程中，但是直到1999年姜帝圭导演的《生死谍变》的成功才诞生了韩国电影的又一个高峰。

虽然《生死谍变》创造了韩国电影史上的最高电影票房纪录，但是1999年以后最高票房纪录几乎每年都会被刷新。

当人们都在津津乐道所谓的“韩国大片”时，2000年朴赞郁导演的《共同警备区JSA》和2001年郭暻泽导演的《朋友》均成功刷新了韩国电影最高票房纪录.2003年康佑硕导演的《实尾岛》和2004年姜帝圭导演的又一部力作《太极旗飘扬》开创了观影人数上千万人次的时代。

姜帝圭和康佑硕导演在韩国电影票房史上扮演了十分重要的角色。

从1993年的《特警冤家》到2003年的《实尾岛》，康佑硕导演了多部成功的电影。

译文交通拥堵和城市交通系统的可持续发展摘要:城市化和机动化的快速增长,通常有助于城市交通系统的发展，是经济性，环境性和社会可持续性的体现,但其结果是交通量无情增加，导致交通拥挤。

道路拥挤定价已经提出了很多次，作为一个经济措施缓解城市交通拥挤，但还没有见过在实践中广泛使用，因为道路收费的一些潜在的影响仍然不明。

本文首先回顾可持续运输系统的概念,它应该满足集体经济发展,环境保护和社会正义的目标.然后,根据可持续交通系统的特点，使拥挤收费能够促进经济增长，环境保护和社会正义。

研究结果表明,交通拥堵收费是一个切实有效的方式，可以促进城市交通系统的可持续发展。

一、介绍城市交通是一个在世界各地的大城市迫切关注的话题。

随着中国的城市化和机动化的快速发展,交通拥堵已成为一个越来越严重的问题,造成较大的时间延迟,增加能源消耗和空气污染，减少了道路网络的可靠性．在许多城市,交通挤塞情况被看作是经济发展的障碍.我们可以使用多种方法来解决交通挤塞,包括新的基础设施建设，改善基础设施的维护和操作,并利用现有的基础设施,通过需求管理策略,包括定价机制,更有效地减少运输密度.交通拥堵收费在很久以前就已提出，作为一种有效的措施,来缓解的交通挤塞情况。

交通拥堵收费的原则与目标是通过对选择在高峰拥挤时段的设施的使用实施附加收费,以纾缓拥堵情况．转移非高峰期一些出行路线,远离拥挤的设施或高占用车辆，或完全阻止一些出行,交通拥堵收费计划将在节省时间和降低经营成本的基础上,改善空气中的质量，减少能源消耗和改善过境生产力。

此计划在世界很多国家和地方都有成功的应用。

继在2０世纪70年代初和8０年代中期挪威与新加坡实行收费环,在20０３年2月伦敦金融城推出了面积收费；直至现在,它都是已经开始实施拥挤收费的大都市圈中一个最知名的例子。

然而,交通拥堵收费由于理论和政治的原因未能在实践中广泛使用。

道路收费的一些潜在的影响尚不清楚,和城市发展的拥塞定价可持续性,需要进一步研究。

It should ensure that the car has a variety of driving conditions necessary for traction, speed, and to ensure coordination between the traction and speed changes and other features that make the car has good power and fuel economy; also ensure the car can reverse, and left and right drive wheels can adapt to the requirements of the differential，And power transmission can be smoothly bonded or completely, the rapid separation as required. Driveline including clutch, transmission, drive shaft, main gear, differential and axle and other parts of the drive train in different ways according to the energy transfer is divided into mechanical transmission, hydraulic transmission, hydraulic, electric transmission and so on. First, the composition of the transmission systemClutch function: 1, the clutch can gradually combined to ensure a smooth start car engines and automotive drivetrain. 2, the clutch can temporarily cut off the engine and drive train, easy engine starting and transmission shift, in order to guarantee smooth drivetrain shift work. 3, the clutch can limit the transmitted torque, to prevent overloading the driveline.Composition: active part, the driven part, the pressing means, separating means and control mechanism.Universal transmission function:in the car any angle and relative position between a pair of shafts to transmit power between changes often occur shaft.The universal drive axleDrive axle gearing (or transmission)power came through deceleration by twisting, changing the direction of power transmission power by deceleration by twisting, (when the engine is longitudinal) after changing the direction of power transmission, assigned to the left and right wheels, making the car running, and allows the drive wheels to the left and right at different speeds. Drive axle assembly is the last of its drivetrain from the main reducer, differential, axle and axle components.Transmission functions: (1)change the transmission ratio: expanding the scope of variation of torque and speed of the drive wheel to adapt to frequent changes in driving conditions, such as start, acceleration, uphill, so that the engine work in favorable conditions. (2) in the direction of rota0 tion of the engine under the same premise, so the car can travel backwards. (3) the use of neutral, interrupt the power transmission, to allow the engine to start, idling, and to facilitate the transmission shift or power output.Second, the transmission consists of：the speed change transmission mechanism and operating mechanism Most ordinary transmission gear and some planetary gear drive. Ordinary gear shift mechanism for general use gears and clutch slip. How associated gear slip displacement gear and gear points. With triple sliding gear shift, a large axial dimension; with displacement sliding gear transmission, compact structure, but smaller than the gear change. There mesh type clutch and friction points. When using the clutch is engaged, the transmission speed difference should stop or very hour, with a friction clutch for shifting in operation at any speed difference, but small carrying capacity, and can not guarantee strict two-axis synchronization. To overcome this drawback, the engagement clutch friction plate tops to, when the first gear wheel driven by the friction plates to the synchronous speed and then joined. Planetary gear transmission brake control gear available.Third, the structural characteristics of the transmission Automatic transmission automatically selects the gear .and has the following salient features: 1.Good driving performance.2.manipulate simple.3.high traffic safety.4. to reduce emissions. 5. You can extend engine and driveline life. 6.increase productivity. but the automatic transmission drawback is:Its structure is more complicated, but also more difficult to repair. Another automatic transmission transmission efficiency is not high enough, of course, by matching engine optimization, lockup, and other measures to increase the number of gears, thetransmission efficiency can be close to the efficiency of the automatic transmission manual transmission level.Fourth, the transmission Category:1), according to the gear ratio change the way: a stepped, stepless and comprehensive formula①stepped: a step-most widely used transmission, which uses a gear drive, with a number of valuation ratios.a gear train used by different: there is a fixed axis (ordinary gear transmission) and the axis of the rotary transmission (planetary gear transmission) two.b. At present, the transmission drive cars and light and medium trucks than the usual 3 to 5 forward gears and one reverse gear.c. In the heavy-duty vehicles using a modular transmission, the use of more stalls, usually made of a combination of two transmissions.②stepless: stepless transmission ratio within a certain range can be varied by an infinite number of levels.a. Are common type and a hydraulic power (dynamic liquid) two.b. Electricity formula also used in the driveline trend widely used, its variable transmission member for DC series wound motor.c. A hydraulic drive unit is a hydraulic torque converter.③comprehensive type: integrated gearbox is defined by the torque converter and gear-type stepped transmission consisting of hydraulic mechanical transmission. Transmission ratio can be made infinitely variable within a few discontinuities between the maximum and minimum range, the current is widely used.2), by manipulating points: Forced manipulation, automatic and semi-automatic actuated actuated①. Forced actuated transmission shift lever operated directly by the driver, used for most cars.②. Robotic gearbox gear ratio selection (shift) is automatic. The driver simply manipulating the accelerator pedal, you can control the speed.③. Semi-automatic gearbox, there are two forms of manipulationa.Kind of common robotic several stalls, the rest of the stalls operated by the driver;b.The other is a preselected type, i.e., the driver in advance with the button selected gear, when the clutch pedal or the accelerator pedal is released, turned an electromagnetic device or hydraulic device to shift.3), by using the method points: manual transmission (MT), the automatic transmission (AT), manual transmission, continuously variable transmission (CVT), double-clutch gearbox and EMT, AMT sequence transmission, etc.Fifth, the transmission worksCar needs transmission, which is by the physical characteristics determined by an automobile engine. First, any engine has a speed limit, speed exceeds this maximum, the engine will explode. Secondly, if read horsepower and its application, you will know when have reached the maximum horsepower and torque, low speed range of the engine. For example, the engine may at 5,500 r / time to produce maximum horsepower. In the vehicle acceleration or deceleration, so that the presence of the transmission gear ratio between the engine and the drive wheels can be changed. By changing the gear ratio, the engine speed can be maintained below the speed limit, and the engine rotation speed zone close to optimum performance. Ideally, the range of the transmission gear ratio change is very large, and thus the engine always operates in the best performance of a single speed. This is a continuously variable transmission (CVT) of the CVT gear ratio range of the concept is virtually no limit. Past, CVT will not work with a four-speed and five-speed transmission contend in cost, size and reliability, so they are not visible in production cars. Currently, the improvement of the design of CVT has been so popular. Toyota Prius is a hybrid car using CVT.A transmission connected to the engine through a clutch. Thus, the same transmission input shaft speed and the engine.Six, synchronizerSince the transmission input shaft and the output shaft to the respective speed of rotation, there will be a "synchronous" change gear problems. Two rotation speed is not the same gear meshing force is bound to happen impact collision damage gear. Therefore, the transmission shift to adopt the old "feet clutch" approach, upshift stay a while in the neutral position, the downshift to refuel door in the neutral position, in order to reduce the speed differential gear. However, this operation is more complex and difficult to grasp accurate. So the designers to create a "synchronizer", by synchronizing allows gear to be engaging to a consistent speed and smooth engagement. There are pressure-type synchronizer, inertial and other types of self-energizing type. Currently on all synchronous transmission inertia synchronizer is used, which is mainly composed of clutch, synchronization lock ring and other components, it is characterized by relying on friction to achieve synchronization. Clutches, synchronized to be joined on the lock ring and ring gears are chamfered (locking angle), the inner cone synchronization lock ring and outer ring gear to be engaged in contact friction cone. Locking cone angle have been made in the design of appropriate choice, conical friction makes meshing gear sets to be quickly synchronized with the ring, but will produce a locking action to prevent the gear meshing before synchronization. When the inner cone synchronization lock ring and outside the ring gear to be engaged cone contact, the role of friction torque gear speed quickly reduce (or increase) to synchronous speed lock ring is equal to both synchronous rotation, gear relative to the genlock loop speed is zero, and thus the moment of inertia also disappeared, then under the force of the push, the clutch unimpeded synchronization lock ring engagement ring, and further engagement with the ring gear to be engaged and to complete shifting process. Transmission and synchronizers implementations from different manufacturers in different ways, but the basic principle is the same. Acting synchronizer is in contact with the canines before, so that the collar and the gear friction contact occurs. Thus, before the canine bonding, you can make the collar and the gear speed to achieve synchronization, as shown: blue cone axis gear engagement ring cone friction between the cone and the collar of the shaft ring and gear synchronization. Slide along the outer collar, so that theengagement gear canines. Automatic transmission fluid coupling function why no increase in torque effect: fluid coupling, only the pump and turbine, turbine oil without changing the flow direction of the guide wheel. When working pump oil to pass turbine wheel, and then through the turbine wheel return pump, oil pump through the turbine wheel return changed the direction of rotation, the flow direction and the opposite direction of rotation of the pump impeller. Engine crankshaft while being rotated, the need to overcome the resistance from the reverse of the turbine oil. Engine power has been weakened. Therefore, only the coupling fluid coupling condition, and never have increased torque conditions.When the car started and low speed high torque is required, and fluid couplings can not meet this need. So early production car with hydraulic coupling has started slow, slow-speed zone speed obvious shortcomings.In order to meet the needs of the car started and needs more torque at low speeds, and Hyundai have all switched to the torque converter. When the torque converter pump wheel fast moving, turbine load and driving resistance by the slower speed limit, between the pump and turbine produces a speed difference. This speed difference exists in the entire variable torque area. This speed difference on the formation of residual energy. That is, since the number of pump rotation is faster than the number of revolutions of the turbine, so that the oil pump to the turbine in turn drives the turbine in addition to, but also the remaining part of the energy, which is the residual energy. The difference between the number of revolutions of the pump impeller and the turbine, the greater the greater the residual energy. This residual fluid coupling in energy become an obstacle to the resistance of crankshaft rotation, and finally converted to heat, wasted. Torque converter is different, the speed difference between the pump and turbine is larger, the better residual energy only when the pump is higher than the number of vortex rotation revolutions to produce residual energy in order to increase the torque. Turbine braking (when the stall point and the starting point) of its maximum torque ratio. Fluid from the pump to turn a turbine, and then by changing the direction of the guide wheel and then return to the pump wheel, between the pump and turbine oil circulation formation. Only the presence of oil in circulation,in order to produce the torque conditions. With the increase in the number of revolutions of the turbine, the torque of the linear decline. After a critical point, the same number of turbines and rotary pumps, oil pump drive rotation of the turbine wheel in addition to, but has no residual energy, oil flow angle is changed to a minimum point, turbine oil returned toward the guide wheel on the back. Because of the one-way clutch is only responsible for the lock, turn left, turn right and not lock, so when the oil shocks on the back of the guide wheel is fixed on the one-way clutches, guide wheels began to rotate, the guide wheel starts spinning the moment is called the critical point . Prior to the critical point after coupling conditions for variable torque conditions, the critical point. Torque converter torque ratio increases with the turbo speed decreases, and decreases the number of revolutions of the turbine increases. I.e., with the running resistance torque increases, according to the running resistance of the automatic stepless variable torque in the low speed region. Torque converter transmission efficiency is increased with the number of revolutions of the turbine increases: only when the pump and turbine speed is close, will have a coupling conditions. Coupling conditions only in the car at high speed only, no coupling conditions at low speeds. As a guide wheel torque-device remains stationary while the torque conditions, the coupling conditions began to rotate. If the guide wheel rotating at the moment when they condition, it shows that the occurrence of a one-way clutch slip faults. When the guide wheel coupling conditions must be rotated, so when you do not spin, there is a one-way clutch catching fault occurred. The automatic transmission has been able to achieve automatic shift work because the driver depresses the throttle position or engine intake manifold vacuum and the traveling speed of the car can command the automatic shift system working, automatic shifting system, the control valves different working conditions will control the transmission gear mechanism and the brake is separated and combined with the release of the brake clutch, and changing the power transmission path of the transmission gear mechanism, transmission gear to achieve transformation.A conventional hydraulic automatic transmission according to changes in traveling speed of the car and the throttle opening degree, the automatic transmissiongear. Its shift control is mechanically converted vehicle speed and the throttle opening signal to control the oil pressure and the oil pressure is applied to both ends of the shift valve, to control the position of the shift valve, thereby changing the shifting actuator elements (clutches and brakes) of the oil. Thus, the work of hydraulic oil into the corresponding actuator, the clutch combination or separation, or release the brake, the control of the planetary gear transmission upshift or downshift to achieve automatic transmission.Electronically controlled hydraulic automatic transmission is added an electronic control system based on Automatic Transmission formed. It does this by monitoring the operating state sensor and switch and automobile engine, the driver's instructions to accept, and the obtained information into an electric signal is input to the electronic control unit. Electronic control unit based on these signals, the shift control valve via the solenoid valve of the hydraulic control apparatus to open or close access shift clutch and brake oil passage, thereby controlling the gear shift timing and transformation, in order to achieve automatic transmission .Torque converter utilizing flow of the liquid, the torque from the engine is transmitted to the rear planetary gear mechanism is increased, at the same time, the hydraulic control apparatus according to the travel required (throttle opening, vehicle speed) to manipulate the planetary gear system to obtain the corresponding The gear ratio and rotational direction, to achieve upshifts, downshifts, forward or backward. The above process, the torque is increased, the throttle opening degree and the vehicle speed signal to the hydraulic control means to manipulate, and change the direction of rotation than the planetary gear transmission mechanism, are performed automatically inside the transmission, the driver does not need to operate, namely, automatic shift (shift). Electronically controlled automatic transmission system: Many modern vehicles equipped with electronically controlled automatic shifting device, can more effectively control the transmission shift, to enhance driving performance, fuel consumption saving effect.专业万文翻译材料译文汽车发动机与驱动轮之间的动力传递装置称为汽车的传动系。

附录C：外文翻译资料Article Source：Business & Commercial Aviation, Nov 20, 2000. 5-87-88 Interactive Electronic Technical Manuals Electronic publications can increase the efficiency of your digital aircraft and analogtechnicians.Benoff, DaveComputerized technical manuals are silently revolutionizing the aircraft maintenance industry by helping the technician isolate problems quickly, and in the process reduce downtime and costs by more than 10 percent.These electronic publications can reduce the numerous volumes of maintenance manuals, microfiche and work cards that are used to maintain engines, airframes, avionics and their associated components."As compared with the paper manuals, electronic publications give us greater detail and reduced research times," said Chuck Fredrickson, general manager of Mercury Air Center in Fort Wayne, Ind.With all the advances in computer hardware and software technologies, such as high quality digital multimedia, hypertext and the capability to store and transmit digital multimedia via CD-ROMs/ networks, technical publication companies have found an effective, cost-efficient method to disseminate data to technicians.The solution for many operators and OEMs is to take advantage of today's technology in the form of Electronic Technical Manuals (ETM) or Interactive Technical Manuals (IETM). An ETM is any technical manual prepared in digital format that has the ability to be displayed using any electronic hardware media. The difference between the types of ETM/IETMs is the embedded functionality and implementation of the data."The only drawback we had to using ETMs was getting enough computers to meet our technicians' demand," said Walter Berchtold, vice president of maintenance at Jet Aviation's West Palm Beach, Fla., facility.A growing concern is the cost to print paper publications. In an effort to reduce costs, some aircraft manufacturers are offering incentives for owners to switch from paper to electronic publications. With an average printing cost of around 10 cents per page, a typical volume of a paper technical manual can cost the manufacturer over $800 for each copy. When producing a publication electronically, average production costs for a complete set of aircraft manuals are approximately $20 per copy. It is not hard to see the cost advantages of electronic publications.Another advantage of ETMs is the ease of updating information. With a paper copy, the manufacturer has to reprint the revised pages and mail copies to all the owners. When updates are necessary for an electronic manual, changes can either be e-mailed to theowners or downloaded from the manufacturer's Web site.So why haven't more flight departments converted their publications to ETM/IETMs? The answer lies in convincing technicians that electronic publications can increase their efficiency."We had an initial learning curve when the technicians switched over, but now that they are familiar with the software they never want to go back to paper," said Fredrickson.A large majority of corporate technicians also said that while they like the concept of having a tool that aids the troubleshooting process, they are fearful to give up all of their marked-up paper manuals.In 1987, a human factors study was conducted by the U.S. government to compare technician troubleshooting effectiveness, between paper and electronic methodology, and included expert troubleshooting procedures with guidance through the events. Results of the project indicated that technicians using electronic media took less than half the time to complete their tasks than those using the paper method, and technicians using the electronic method accomplished 65 percent more in that reduced time.The report also noted that new technicians using the electronic technical manuals were 12-percent more efficient than the older, more experienced technicians. (Novices using paper took 15 percent longer than the experts.)It is interesting that 90 percent of the technicians who used the electronic manuals said they preferred them to the paper versions. This proved to the industry that with proper training, the older technicians could easily transition from paper to electronic media.Electronic publications are not a new concept, although how they are applied today is. "Research over the last 20 years has provided a solid foundation for today's IETM implementation," said Joseph Fuller of the U.S. Naval Surface Warfare Center. "IETMs such as those for the Apache, Comanche, F-22, JSTAR and V-22 have progressed from concept to military and commercial implementation."In the late 1970s, the U.S. military investigated the feasibility of converting existing paper and microfilm. The Navy Technical Information Presentation System (NTIPS) and the Air Force Computer- based Maintenance Aid System (CMAS) were implemented with significant cost savings.The report stated that transition to electronic publications resulted in reductions in corrective maintenance time, fewer false removals of good components, more accurate and complete maintenance data collection reports, reduction in training requirements and reduced system downtime.The problem that the military encountered was ETMs were created in multiple levels of complexity with little to no standardization. Options for publications range from simple page-turning programs to full-functioning automated databases.This resulted in the classification of ETMs so that the best type of electronic publication could be selected for the proper application.Choosing a LevelWith all of the OEM and second- and third-party electronic publications that are available it is important that you choose the application level that is appropriate for your operation.John J. Miller, BAE Systems' manager of electronic publications, told B/CAthat "When choosing the level of an ETM/IETM, things like complexity of the aircraft and its systems, ease of use, currency of data and commonality of data should be the deciding factors; and, of course, price. If operational and support costs are reduced when you purchase a full-functioning IETM, then you should purchase the better system."Miller is an expert on the production, sustainment and emerging technologies associated with electronic publications, and was the manager of publications for Boeing in Philadelphia.Electronic publications are classified in one of five categories. A Class 1 publication is a basic electronic "page turner" that allows you to view the maintenance manual as it was printed. With a Class 2 publication all the original text of the manual is viewed as one continuous page with no page breaks. In Class 3, 4 and 5 publications the maintenance manual is viewed on a computer in a frame-based environment with increasing options as the class changes. (See sidebar.)Choosing the appropriate ETM for your operation is typically limited to whatever is being offered on the market, but since 1991 human factors reports state the demand has increased and, therefore, options are expected to follow.ETM/IETM ProvidersCompanies that create ETM/IETMs are classified as either OEM or second party provider. Class 1, 3 and 4 ETM/IETMs are the most commonly used electronic publications for business and commercial operators and costs can range anywhere from $100 to $3,000 for each ETM/ IETM. The following are just a few examples ofETM/IETMs that are available on the market.Dassault Falcon Jet offers operatorsof the Falcon 50/50EX, 900/900EX and 2000 a Class 4 IETM called the Falcon Integrated Electronic Library by Dassault (FIELD). Produced in conjunction with Sogitec Industries in Suresnes Cedex, France, the electronic publication contains service documentation, basic wiring, recommended maintenance and TBO schedules, maintenance manual, tools manual, service bulletins, maintenance and repair manual, and avionics manual.The FIELD software allows the user to view the procedures and hot- link directly to the Illustrated parts catalog. The software also enables the user to generate discrepancy forms, quotation sheets, annotations in the manual and specific preferences for each user.BAE's Miller said most of the IETM presentation systems have features called "Technical Notes." If a user of the electronic publication notices a discrepancy or needs to annotate the manual for future troubleshooting, the user can add a Tech Note (an electronic mark-up) to the step or procedure and save it to the base document. The next time that or another user is in the procedure, clicking on the tech note icon launches a pop-up screen displaying the previous technician's comments. The same electronic transfer of tech notes can be sent to other devices by using either a docking station or through a network server. In addition, systems also can use "personal notes" similar to technical notes that are assigned ID codes that only the authoring technician can access.Requirements for the FIELD software include the minimum of a 16X CD-ROM drive,Pentium II 200 MHz computer, Windows 95, Internet Explorer 4 SP 1 and Database Access V3.5 or higher.Raytheon offers owners of Beech and Hawker aircraft a Class 4 IETM called Raytheon Electronic Publication Systems (REPS). The REPS software links the frame-based procedures with the parts catalog using a single CD-ROM.Raytheon Aircraft Technical Publications said other in- production Raytheon aircraft manual sets will be converted to the REPS format, with the goal of having all of them available by 2001. In addition Raytheon offers select Component Maintenance Manuals (CMM). The Class 1 ETM is a stand-alone "page-turner" electronic manual that utilizes the PDF format of Adobe Acrobat.Other manufacturers including Bombardier, Cessna and Gulfstream offer operators similar online and PDF documentation using a customer- accessed Web account.Boeing is one manufacturer that has developed an onboard Class 5 IETM. Called the Computerized Fault Reporting System (CFRS), it has replaced the F-15 U.S. Air Force Fault Reporting Manuals. Technologies that are currently being applied to Boeing's military system are expected to eventually become a part of the corporate environment.The CFRS system determines re-portable faults by analyzing information entered during a comprehensive aircrew debrief along with electronically recovered maintenance data from the Data Transfer Module (DTM). After debrief the technicians can review aircraft faults and schedule maintenance work to be performed. The maintenance task is assigned a Job Control Number (JCN) and is forwarded electronically to the correct work center or shop. Appropriate information is provided to the Air Force's Core Automated Maintenance System (CAMS).When a fault is reported by pilot debrief, certain aircraft systems have the fault isolation procedural data on a Portable Maintenance Aid (PMA). The JCN is selected on a hardened laptop with a wireless Local Area Network (LAN) connection to the CFRS LAN infrastructure. The Digital Wiring Data System (DWDS) displays aircraft wiring diagrams to the maintenance technician for wiring fault isolation. On completion of maintenance, the data collected is provided to the Air Force, Boeing and vendors for system analysis.Third party IETM developers such as BAE Systems and Dayton T. Brown offer OEMs the ability to subcontract out the development of Class 1 through 5 ETM/IETMs. For example, Advantext, Inc. offers PDF and IPDF Class 1 ETMs for manufacturers such as Piper and Bell Helicopters. Technical publications that are available include maintenance manuals, parts catalogs, service bulletins, wiring diagrams, service letters and interactive parts ordering forms.The difference between the PDF and IPDF version is that the IPDF version has the ability to search for text and include hyperlinks. A Class 1 ETM, when printed, is an exact reproduction of the OEM manuals, including any misspellings or errors. Minimum requirements for the Advantext technical publications is a 486 processor, 16 MB RAM with 14 MB of free hard disk space and a 4X CD-ROM or better.Aircraft Technical Publishers (ATP) offers Class 1, 2 and 3 ETM/ IETMsfor the Beechjet 400/400A; King Air 300/ 350, 200 and 90; Learjet 23/24/25/28/29/35/36/55; Socata TB9/10/20/21 and TBM 700A; Sabreliner 265-65, -70 and -80; andBeech 1900. The libraries can include maintenance manuals, Illustrated parts bulletins, wiring manuals, Airworthiness Directives, Service Bulletins, component maintenance manuals and structural maintenance manuals. System minimum requirements are Pentium 133 MHz, Windows 95 with 16 MB RAM, 25 MB free hard disk space and a 4X CD-ROM or better.Additional providers such as Galaxy Scientific are providing ETM/ IETMs to the FAA. This Class 2, 3 and 4 publication browser is used to store, display and edit documentation for the Human Factors Section of the administration."Clearly IETMs have moved from research to reality," said Fuller, and the future looks to hold more promise.The Future of Tech PubsThe use of ETM/IETMs on laptop and desktop computers has led research and development corporations to investigate the human interface options to the computer. Elements that affect how a technician can interface with a computer are the work environment, economics and ease of use. Organizations such as the Office of Naval Research have focused their efforts on the following needs of technicians: -- Adaptability to the environment.-- Ease of use.-- Improved presentation of complex system relationship.-- Maximum reuse and distribution of engineering data.-- Intelligent data access.With these factors in mind, exploratory development has begun in the areas of computer vision, augmented reality display and speech recognition.Computer vision can be created using visual feedback from a head- mounted camera. The camera identifies the relative position and orientation of an object in an observed scene, and the object is used to correlate the object with a three-dimensional model. In order for a computer vision scenario to work, engineering data has to be provided through visually compatible software.When systems such as Sogitech's View Tech electronic publication browser and Dassault Systemes SA's Enovia are combined, a virtual 3D model is generated.The digital mockup allows the engineering information to directly update the technical publication information. If a system such as CATIA could be integrated into a Video Reference System (VRS), then it could be possible that a technician would point the camera to the aircraft component, the digital model identifies the component and the IETM automatically displays the appropriate information.This example of artificial intelligence is already under development at companies like Boeing and Dassault. An augmented reality display is a concept where visual cues are presented to users on a head-mounted, see-through display system.The cues are presented to the technician based on the identification of components on a 3D model and correlation with the observed screen. The cues are then presented as stereoscopic images projected onto the object in the observed scene.In addition a "Private Eye" system could provide a miniature display of the maintenance procedure that is provided from a palm- size computer. Limited success hascurrently been seen in similar systems for the disabled. The user of a Private Eye system can look at the object selected and navigate without ever having to touch the computer. Drawbacks from this type of system are mental and eye fatigue, and spatial disorientation.Out of all the technologies, speech recognition has developed into an almost usable and effective system. The progression through maintenance procedures is driven by speaker-independent recognition. A state engine controls navigation, and launches audio responses and visual cues to the user. Voice recognition software is available, although set up and use has not been extremely successful.Looking at other industries, industrial manufacturing has already started using "Palm Pilot" personal digital assistants (PDAs) to aid technicians in troubleshooting. These devices allow the technician to have the complete publication beside them when they are in tight spaces. "It would be nice to take the electronic publications into the aircraft, so we are not constantly going back to the work station to print out additional information," said Jet Aviation's Berchtold.With all the advantages that a ETM/ IETM offers it should be noted that electronic publications are not the right solution all of the time, just as CBT is not the right solution for training in every situation. Only you can determine if electronic publications meet your needs, and most technical publication providers offer demo copies for your review.
