附录五中英文资料Multi-channel data collection and analysisof the design and applicationAbstract:The Paper mainly introduces a multichannel data acquisition and analysis system composed of one PC and one measuring instrument. The system can test eight products parallelly. It reduces the test cost and improves work efficiency. The paper also gives the hardware structure and software flow diagr am of the system. The application in the gyro test is also introduced briefly.Key words:communication prot;data acquisition; gyro; testWith the development of computer technology and the digital measuring instrument, usually by computer and measuring instruments to communicate with each other in real-time data collection and use of computer powerful computing capability to conduct the analysis of the data processing. Particularly in the large volume of data, measuring the length of time occasions, such as the Gyro-tilt test, using computer for automatic control of measuring instruments, automatic data acquisition and analysis it is particularly important, can save a lot of manpower and material resources to improve work efficiency, reduce costs , The conventional method of testing is usually a measuring instrument at the same time can only test a product, namely a computer and a measuring instrument test system can only be composed of serial testing. To test multiple products at the same time, they need multiple systems, testing products in large volume, low efficiency, such as the composition of several sets of test system, an increase of cost. First on a machine with a PC and a measuring instrument consisting of 8-way data collection and analysissystem, which can carry out multiple sets of product testing, at no additional cost on the basis of a computer give full play to the advantages of automatic test, Improve work efficiency.1 PrincipleThe system hardware and software system. A PC through a RS232 port and a measuring instrument connected, PC-parallel port (LPT) and an 8-way channel selector attached to a 8-way connector will channel selector were connected with a number of test products.The working principle as shown in Figure 1. The course of testing, computer through the parallel port 8-way control channel selection, were open different channels, each channel for data transmission by choosing to measuring instruments, measuring instruments through the RS232 port to the computer data sent to save, A complete cycle of all channels of data collection, and this has also tested a number of product features.Figure 1 system block diagram of workThroughout the course of testing, all the control operations have completed the software automatically, without human intervention.2 hardware designThe system is mainly to use the computer onboard RS232 communication ports and digital measuring instrument of communication port connecting communications, re-use LPT parallel port on a 8-way channel selector for access control. 8-way channel of choice for an 8-elected one of analog switches and related circuit, the control signals from the computer's parallel port to provide and meet shown in table 1.Table1 The relation between channel selection and port output8-way channel selector industry can use the SCM, subject to additional controls, select RS232 serial port as data transmission, because the RS232 port is the computer and measuring instruments on the standard configuration, communicate with each other without additional hardware , Easy to use. In addition, a serial communication-only a bit, with only a standard data-voltage potential, hence more difficult in data errors. In a parallel port to transfer data 8-bit, data transmission speed, but the data vulnerable to interference. Transmission distance in a shorter amount of data transmission larger circumstances, may be parallel port (such as GPIB, LPT, etc.) to communicate. In addition, since LPT parallel port may signal transmission, channel selection is suitable for the control port.System in the course of work, good access control modules and data acquisition module synchronization is particularly important because different channels of datastorage needs of the corresponding data buffer pool, which is controlled by software.3 software designThe whole system software design is the most important part. Software system from the bottom of the communication protocol can be divided into functional three-tier module and user interface. Software design in the use of multi-threaded Windows technology, the technology for data collection procedures can effectively accelerate the reaction time and increase the efficiency of implementation. The procedures used in a separate thread for data collection, so the guaranteed maximum energy collection of real-time; using another thread at the same time data processing, such procedures to avoid a single-threaded the same time only the implementation of a functional deficiencies. Especially when the amount of data collection, data processing task, using multi-threaded technology will greatly improve the efficiency of the system as a whole.3.1 Data Acquisition ModuleData acquisition modules to eight channels of data in a cycle of all the acquisition to the computer, and save the channel, and the corresponding data in the buffer. Its procedures diagram shown in Figure 2.Fig 2 Flow diagram of data acquisitionAt the beginning of procedures, with the choice of control and store data buffer at the same time to switch to the same channel, 8-way data collection cycle and command judgement, in the end not received orders, has recycling collection to do.Multi-channel data acquisition process the data vulnerable to interference, especially in the fast-channel switching, the data vulnerable to fluctuations, as shown in Figure 3. At this time if the data collection, will be collecting the wrong data, the need to add some software algorithms to prevent this from happening. If we develop the automated data tracking algorithm to automatically track each channel data to determine whether the channel in a stable state, and only the stability of dataacquisition, the volatility of other data. In addition, the software can also add some filtering algorithm (such as limiting filter, etc.) to filter out man-made interference or other factors caused by the mutation data. Limiting filter for(1)Figure 3 channel switching, the data volatilityWhen the new collected data and the data before a difference to the absolute value of more than one set of values that the data is invalid, and the previous data from the current data.3.2 Data Analysis ModuleIn the data analysis module can be added if the algorithm analysis, graphics display and print output, and other useful features, such as gyroscopes and stability in the standard deviation algorithm can function in the course of testing real-time calculation of zero stability, and through chart shows. Zero stability calculation formula as follows:(2)According to first-(2) to prepare an algorithm function, and then call in the analysis module. Analysis module diagram of the procedure shown in Figure 4.Figure 4 data analysis process flow chartBecause the system uses multi-threaded technology, in the cycle of operation and will not affect the acquisition module's operation. The module also in its algorithm in the function of any expansion, forming a algorithm to adapt to different procedures for data analysis.In addition, software design, a friendly user interface is necessary in the process of the functions from the package, through a unified interface to users, to reduce operating difficulties and enhance efficiency.4 system test resultsFigure 5 to 8 in the analysis of data acquisition systems, at the same time two three-axis gyro and a single axis gyroscope total of seven road test data of thesituation. Its precise data collection, data analysis can be conducted at the same time, and through real-time charts, user-friendly, easy to operate.Figure 5 8 Data Collection and Analysis System5 ConclusionMulti-channel data acquisition and analysis system for the hardware requirements simple, easy to set up, can be applied to various tests occasions, it can also test multiple products, thereby reducing the cost and enhance efficiency. As a result of a multi-threaded technology, the speed of data acquisition systems and hardware only (instrument) and the response speed of the speed of Communication. With the collection and analysis software algorithm has nothing to do.PAD programming tools can be used to develop a data collection, data analysis, graphics display and print output, and other powerful features and friendly user interface of our software. Software modular design and easy to carry out expansion, according to different algorithm for data analysis at the request of upgrades, and hardware can remain the same. The system give full play to the use of computers and measuring instruments of mutual communication, automation and test advantage.多路数据采集与分析系统的设计及应用摘要:介绍了用一台PC机和一台测量仪表组成的8路数据采集与分析系统。

Rather than prescribing a "correct" decision, the AHP helps people to determine one that suits their needs and wants. Based on mathematics and psychology, it was developed by Thomas L. Saaty in the 1970s and has been extensively studied and refined since then. The AHP provides a comprehensive and rational framework for structuring a problem, for representing and quantifying its elements, for relating those elements to overall goals, and for evaluating alternative solutions. It is used throughout the world in a wide variety of decision situations, in fields such as government, business, industry, healthcare, and education.Several firms supply computer software to assist in using the process.Users of the AHP first decompose their decision problem into a hierarchy of more easily comprehended sub-problems, each of which can be analyzed independently. The elements of the hierarchy can relate to anyaspect of the decision problem—tangible or intangible, carefully measured or roughly estimated, well- or poorly-understood—anything at all that applies to the decision at hand.Once the hierarchy is built, the decision makers systematically evaluate its various elements, comparing them to one another in pairs. In making the comparisons, the decision makers can use concrete data about the elements, or they can use their judgments about the elements' relative meaning and importance. It is the essence of the AHP that human judgments, and not just the underlying information, can be used in performing the evaluations.The AHP converts these evaluations to numerical values that can be processed and compared over the entire range of the problem. A numerical weight or priority is derived for each element of the hierarchy, allowing diverse and often incommensurable elements to be compared to one another in a rational and consistent way. This capability distinguishes the AHP from other decision making techniques.In the final step of the process, numerical priorities are derivedfor each of the decision alternatives. Since these numbers represent the alternatives' relative ability to achieve the decision goal, they allow a straightforward consideration of the various courses of action.Uses and applicationsWhile it can be used by individuals working on straightforward decisions, Analytic Hierarchy Process (AHP) is most useful where teamsof people are working on complex problems, especially those with high stakes, involving human perceptionsand judgments, whose resolutions have long-term repercussions. Ithas unique advantages where important elements of the decision are difficult to quantify or compare, or where communication among team members is impeded by their different specializations, terminologies, or perspectives.Decision situations to which the AHP can be applied include:, Choice - The selection of one alternative from a given set of alternatives,usually where there are multiple decision criteria involved., Ranking - Putting a set of alternatives in order from most toleastdesirable Prioritization - Determining the relative merit of a setofalternatives, as opposed to selecting a single one or merely ranking them, Resource allocation - Apportioning resources among a set of alternatives, Benchmarking - Comparing the processes in one's own organization withthose of other best-of-breed organizations, Qualitymanagement - Dealing with the multidimensional aspects of quality and quality improvementThe applications of AHP to complex decision situations have numbered in the thousands, and have produced extensive results in problems involving planning, Resource allocation, priority setting, and selection among alternatives. Other areas have included forecasting, toreotal quality management, business process re-engineering ,quality function deployment, and the Balanced Scorecard.ManyAHP applications are never reported to the world at large, because they take place at high levels of large organizations where security and privacy considerations prohibit their disclosure. But some uses of AHP are discussed in the literature. Recently thesehave included:, Deciding how best to reduce the impact of global climate change (Fondazione Eni Enrico Mattei), Quantifying the overall quality of software system(Microsoftcorporation), Selecting university faculty(Bloomsburg University of Pennsy), Deciding where to locate offshore manufacturing plants(University ofCambridge), Assessing risk in operating cross-country prtroleumpipelines(AmericanSociety of Civil Engineers), Deciding how best to manage U.S. watersheds(U.S. Department of Agriculture)AHP is sometimes used in designing highly specific procedures for particular situations, such as the rating of buildings by historic significance. It was recently applied to a project that uses video footage to assess the condition of highways inVirginia. Highway engineers first used it to determine the optimum scope of the project, then to justify its budget to lawmakers.AHP is widely used in countries around the world. At a recent international conference on AHP, over 90 papers were presented from 19 countries, including the U.S., Germany, Japan, Chile , Malaysia, andNepal. Topics covered ranged from Establishing Payment Standards for Surgical Specialists, to Strategic TechnologyRoadmapping, to Infrastructure Reconstruction in Devastated Countries. AHP wasintroduced in China in 1982, and its use in that country has expanded greatly since then—its methods are highly compatible with the traditional Chinese decision making framework, and it has been used for many decisions in the fieldsofeconomics,energy,management,environment,traffic,agriculture, industry, and the military.Though using AHP requires no specialized academic trainning, the subject is widely taught at the university level—one AHP software provider lists over a hundredcolleges and universities among its clients. AHP is considered an important subject in many institutions of higher learning, includingschools of engineering and Graduate school of Business . AHP is also an important subject in the quality field, and is taught in many specialized courses including Six Sigma, Lean Six Sigma, and QFD.In China, nearly a hundred schools offer courses in AHP, and many doctoral students choose AHP as the subject of their research and dissertations. Over 900 papers have been published on the subject inthat country, and there is at least one Chinese scholarly journal devoted exclusively to AHP.ImplementationAs can be seen in the examples that follow, using the AHP involves the mathematical synthesis of numerous judgments about the decision problem at hand. It is not uncommon for these judgments to number in the dozens or even the hundreds. While the math can be done by hand or with a calculator, it is far more common to use one of several computerized methods for entering and synthesizing the judgments. The simplest of these involve standard spreadsheet software, while the most complex use custom software, often augmented by special devices for acquiring the judgmentsof decision makers gathered in a meeting room.Steps in using the processThe procedure for using the AHP can be summarized as:1. Model the problem as a hierarchy containing the decision goal,the alternativesfor reaching it, and the criteria for evaluating the alternatives.2. Establish priorities among the elements of the hierarchy bymaking a series ofjudgments based on pairwise comparisons of the elements. For example, whencomparing potential real-estate purchases, the investors might say they preferlocation over price and price over timing.3. Synthesize these judgments to yield a set of overall prioritiesfor the hierarchy.This would combine the investors' judgments about location, priceand timingfor properties A, B, C, and D into overall priorities for each property.4. Check the consistency of the judgments.5. Come to a final decision based on the results of this process.CriticismsThe AHP is now included in most operations research and management science textbooks, and is taught in numerous universities; it is used extensively in organizations that have carefully investigated its theoretical underpinnings. While the general consensus is that it isboth technically valid and practically useful, the method does have its critics.In the early 1990s a series of debates between critics andproponents of AHP was published in Management Science and The Journal of the Operational ResearchSociety. These debates seem to have been settled in favor of AHP.Occasional criticisms still appear. A 1997 paper examined possible flaws in the verbal (vs. numerical) scale often used in AHP pairwise comparisons. Another from the same year claimed that innocuous changesto the AHP model can introduce order where no order exists. A 2006 paper found that the addition of criteria for which all alternatives perform equally can alter the priorities of alternatives. An in-depth paper discussing the academic criticisms of AHP was published in Operations Research in2001.Most of the criticisms involve a phenomenon called rank reversal, discussed inthe following section.Rank reversalMany people hear about rank reversal and assume that there is some sort of proven principle about it that needs to be upheld in making decisions. That assumption has led to much misunderstanding of AHP and other decision making techniques. In actuality, rank reversal is a complex matter about which there are many conflicting ideas and opinions. This section offers a simplified explanation of the situation.Decision making involves ranking alternatives in terms of criteriaor attributes of those alternatives. It is an axiom of some decision theories that when new alternatives are added to a decision problem, the ranking of the old alternatives must not change. But in the real world, adding new alternatives can change the rank of the old ones. These rank reversals do not occur often, but the possibility of their occurrencehassubstantial logical implications about the methodology used to make decisions, the underlying assumptions of various decision theories, etc.A simple example will demonstrate the phenomenon of rank reversal: Consider a pretty girl in a small town. She's having a party next week, and she wants to buy a dress that will impress her guests. She visitsthe town's only dress store and goes to the rack of party dresses. There are five such dresses, and after long consideration she ranks them by desirability as follows:Rank Style Color Price1 Style A Blue $1092 Style A Green $1093 Style B Red $1194 Style C Yellow $995 Style D Off-White $149Now imagine that she enters the back room and sees the store'sentire inventory of dresses. The dresses she has looked at in Styles B, C, and D are the only ones of their kind, but there are four more StyleA dresses in green and eight more Style A dresses in blue. In the language of decision science, these dresses are copies of the existing alternatives. In our one-store small town scenario, there's a reasonable chance that one or more party guests would buy and wear one of the copies.When made aware of these new alternatives, our fashion-consciousgirl might rank her choices in a different order. Considering her great embarrassment if a guest were to wear the same dress that she did, she might rank her choices like this:OldRank Style Color PriceRank1 3 Style B Red $1192 4 Style C Yellow $993 5 Style D Off-White $1494 2 Style A Green $1095 1 Style A Blue $109Notice that the rankings of the two Style A dresses have reversed (since there are more copies of the blue dress than of the green one). Not only that, but Style A has gone from the most preferred style to the least preferred. Rank reversal has occurred. Axioms of decision theories have been violated. Scholars and researchers can cry"foul," or impugn the method by which the girl has made her choice, but there is no denying that in the world of our example, ranks havebeen reversed. There is no doubt that the reversal is due to the introduction of additional alternatives that are no different from the existing ones.The above is but one example of rank reversal. Rank reversal canalso occur when additional alternatives are added/removed that are not copies of the original alternatives (e.g., red and yellow dresses in completely different styles). Another example of rank reversal occurred in the 2000 U.S. presidential election. Ralph Nader was an 'irrelevant' alternative, in that he was dominated by both the Democrat and Republican candidates. However, since he attracted more votes from those who would have voted Democrat rather than Republican, his presence caused the ranks to reverse. Put another way, if Nader were not in the race, it is widely accepted that Al Gore would have won.There are two schools of thought about rank reversal. One maintains that new alternatives that introduce no additional attributes should not cause rank reversal under any circumstances. The other maintains that there are both situations in which rank reversal is not reasonable as well as situations where they are to be expected. The current version of the AHP can accommodate both these schools — its Ideal Mode preserves rank, while its Distributive Mode allows the ranks to change. Either mode is selected according to the problem at hand.层次分析法层次分析法(AHP)是一种帮助人们处理复杂决策的结构化技术,比起一种指定的“正确”的方法,层次分析法能帮助人们决定哪一种是更适合他们的需求。

例如,提高产品价格会增加单位利润,但可能会减少销量ù会产生较高还是较低的总利润?或者,联邦贴现率的下降会如何影响房地产贷款的收益?为了帮助分析人员根据历史趋势做出有根据的预测,Microsoft 在SQL Server 2000 中提供了分析服务,在SQL Server 7.0 中提供了OLAP 服务。

这些服务都提供OLAP 功能,能够将存储在SQL Server(或任何其他OLE DB 兼容的数据源)上的数据处理成多维数据结构,称为多维数据集。

多维数据集简化了趋势分析和建立实体间交互方式联系的过程。

例如,房地产投资者采用现金流模型来区分一组具有共同特征(如:地产类型、地理位置和利率范围)的贷款,并预测各种事件的影响。

如果贷款提前偿还或者借款人违约,后果将会如何?此类不可预测的事件会如何影响贷款所担保的债券的收益。

从包含几百笔贷款的清单中选择并区分具有分析特征的贷款是需要相当技巧的。

分析服务和OLAP 服务有助于在各组贷款间建立联系,以便分析人员能够建立贷款假设模型。

为了帮助客户的房地产分析人员预测商业抵押证券的业绩,我们的开发小组需要设计一个以各种方式(如:利率、到期期限或地产位置)来简化贷款分类的系统。

信息系统外文文献翻译---系统的分析与设计

信息系统外文文献翻译---系统的分析与设计

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。

附录二Information Systems Analysis and DesignThis class reconstructs the classical computer science topics of "systems analysis and design" -- mapping information flows and data modeling -- within a framework derived from industrial design. Compared with the traditional approach, our focus of attention will shift from systems to services, mainframes to networks, the desktop to the street, organizational workplaces to institutionally organized relationships, cognition to physical activity, and individual users to communities of practice. The class will be organized around presentations by interdisciplinary teams, with minimal lecturing and written work. We will attend closely to the design process, and the teams' own experiences will become raw material for their projects.Two books are required: David G. Messerschmitt, Networked Applications: A Guide to the New Computing Infrastructure, Morgan Kaufman, 1999. This is an outstanding plain-language introduction to the structure of modern information systems.Donald A. Norman, The Invisible Computer, MIT Press, 1999. This is a polemic against the personal computer and in favor of a new generation of diverse and specialized computing devices.Another book is recommended:Jeffrey L. Whitten and Lonnie D. Bentley, Systems Analysis and Design Methods, fourth edition, Irwin McGraw-Hill, 1998. This is a thorough introduction to the conventional practice of systems analysis and design. If you are going to work with people who have the conventional training then it will be useful reference book. But as I say, I regard this material as out-of-date.Here are summaries of the group projects from week to week: Assignment for week 2: Team-Building Exercise.Everyone writes down their skill set and gets copies of everyone else's. Class members then form themselves into teams. Each team's members discuss their past and future, and how they complement one another. They draw a diagram that gives clear form to the conclusions they have reached, and they design a presentation around it.Assignment for week 3: Seeing information happen. Each team gets a distinct assignment, all of which involve going out in the world and watching information happen. Bring back what you've observed and show us. If you use what you've learned in other classes about information seeking then that's great. But we really want you to be observant and name things, and learn how to show what you've seen in a way that changes how other people see the world.Assignment for week 4: Growth of the technology.Each team again gets a distinct assignment, this time involving library work on the state of information technology ten years from now. Because of Moore's Law and related phenomena, we can predict reasonably well the quantitative properties of computing. Processors, for example, will be 100 times faster. What about mass storage, memory chips, wireline and wireless bandwidths, penetration rates of the technologies both domestically and globally, and so on? What important standards will be widely deployed by then? Show us what you've found.Assignment for week 5: Layering.Building on last week, we will do an exercise about the concept of a platform: a service upon which a diversity of other services can be built. The hard part is figuring out what belongs in the generic service, and what the interface should look like between the platform and the services that are built on it. This is going to be a central concept for design in the future. By this time we will have discussed several examples of platforms.Assignment for week 6: Show us your collaboration patterns.All the while you've been documenting your team's work process. This might mean keeping notes,taking pictures, drawing diagrams, videotaping, saving your work, etc. You have probably also settled into something of a routine. Show us how you work together. Along the way we will offer several ideas about what to look for. For example, where is the borderline between "routine" and "improvised"? This will be important in the coming weeks as we mess with the traditional concepts of systems analysis. This is the first week of a six-week iterative design exercise.Assignment for week 7: Ontology of collaborative work. Data modeling is the only idea from traditional systems analysis that is intellectually hard, so we will spend some extra time in class working an example of it. Then your assignment will be to model the data that will be required to implement one or more of your prospective services. Whereas earlier assignments have called on you to invent your own representation schemes, for this assignment we'll have you use a conventional notation scheme for data models. Having done so, sketch an information service that you might like to design to support collaborative work activities.Assignment for week 8: Service design. Now it is time to spell out the details of a potential information service for collaborative work. To prepare for this, think about your service from several angles. What institutional roles are people playing as they use the service? Where are they located? What actions do they need to take? Who gets access to what information? Who creates the data that goes in the databases? Which parts of the data should be structured, and what should the structure be? What existing services does your service exchange data with? And so on. Having explored all of these questions, draw a dataflow diagram for the service you are designing, decomposing the design into enough component processes and databases to get a clear idea of its properties.Assignment for week 9: Information ing cardboard, crayons, glue, and other materials found in kindergarten classrooms, build a mockup of one or more of your services. Show what your service will look like in practice, and tell us how it is comprehensible. We will have discussed some examples of information design, including several that have nothing to do with computers. We wantcomputers to be more like the diagrams in Edward Tufte's books. We also want them to be more like the information appliances that Norman argues for.Assignment for week 10: Service architecture. Having sketched first the insides and then the outsides of your service, it will be time to return to the inside, applying serious architectural concepts this time. How are the processes and databases that comprise your service divided among the various networked devices that they run on? You will have been reading Messerschmidt throughout the quarter, and this is where you will apply everything in that book.Assignment for finals week.We don't imagine that anyone will be around during finals week to see your work, and so instead we will have each group videotape a final presentation that we can put on the Web. This will include your service mockup, its information design and internal architecture, how it works cognitively, how the information flows, and generally how it works as a service in the full sense.MIS Application Server: Easy back-end adminstrationAccurate information is the first step to better planning, reporting and analysis. In many companies, however, this information is stored in several formats across multiple locations. MIS Application Server brings this information together in a single analytic platform.Test thousands of scenariosHow much revenue will our new product generate? Should we split our sales cost center into direct and indirect sales? What if I only invested, 10% of my marketing budget into advertising?Managers test these and thousands of other scenarios during each and every budget planning. Let MIS Application Server support you throughout the process. Its unique “splashing” technology automatically allocates your budget into different projects –down to any desired level of detail. Once you are satisfied with your results, just write back your finalized budget into the database, where you can later access it for comparing budget-actual variances.When changes arise in your budget structure, you can update these quickly from a familiar Excel environment. This unparalleled planning flexibility is powered by the multidimensional real-time OLAP database, MIS Alea.信息系统分析和设计这种重建“系统分析和设计”的古典计算机科学题目 -- 绘图资料流动和数据模型 -- 从工业设计图得到的一种框架。

文献翻译技巧

文献翻译技巧

先确保你真的把原文读懂了,不仅仅是字面上的,而是完全理解它在说什么,表达怎样的观点。

然后结合国内相关领域的表达方式来组织语言。

注意不要依主观取向随意添加原文没有明确传达的内容或删改,更不要遇到似懂非懂的句子不经严谨查证就随意混过去。

也不建议大幅跳脱原文行文,除非你有绝对的自信不会造成错译、漏译、过译、曲译的问题。

谨记,你的职责是「为原作者忠实传话」而不是「消化吸收后再论述」。

措辞方面,鉴于英文学术文献往往采用复杂的句式结构,注意避免翻译腔。

除了特定术语表达外,建议选词以精准为前提,兼顾平实易懂,尽可能简洁。

初译完成后,抛开原文,以初读者的心态重新通读译文全文,看看是否能读懂自己译文的每一句话都在讲什么,论述是否符合基本的相关常识,与原文传达主旨是否一致,句子、段落之间的逻辑关系是否成立、统一,等等。

这个步骤也可请对该领域有了解的朋友代劳。

如果你发现自己能读懂,翻译起来却难以下笔,那么问题很可能出在你的中文表达能力不足。

这种情况下,建议是多阅读一些相关领域内的原创中文文本(而非翻译过来的文本),从中把握语感,然后再应用到自己的翻译文本中。

需要的主要能力在于,1充分利用搜索引擎;2强大的学习能力。

可用的技巧包括,拆分句子结构;将翻译结果,返回搜索引擎进行验证;学习行业知识。

另外,自己在翻译的过程中,不能把翻译当成目的,而是要把学习当成目的。

在大学里,有很多老师曾是外交部、国内外高官的翻译,从他们身上得到最重要的经验之一就是:对于任何不懂的行业,优秀的翻译都能靠自学,将自己变成一个初通行业门道的人甚至专家。

1.拆分句子结构,拆成术语+非术语:因为翻译中,第一个技术难点在于术语,第二个技术难点才是行业知识。

因为有时候整句话的术语翻译完后,虽然整个句子的意思你还是看不懂,但是从翻译角度来讲,已经翻译无误了,这个技巧很类似于机器翻译。

我们仅仅翻译知道的部分,先留下术语不翻译。

只需要填进去术语,然后你就翻对了。

文献资料翻译怎么才能做好?知行翻译认为这4点值得参考

文献资料翻译怎么才能做好?知行翻译认为这4点值得参考

随着国民经济的不断发展,中国传统文化正在走出国门,面向世界,并且有很多外国人对中国传统文化有着浓厚的兴趣,他们了解中国传统文化的重要途径就是翻看一些记载传统文化的文献资料,所谓文献资料,就是通过一定的方法和手段,运用一定的意义和记录体系在一定载体的有历史价值和研究价值的知识,文献资料是记录,积累,传播和继承知识的最有效手段,是人类社会活动中获取情报的最基本,最主要的来源,也是交流传播情报的最基本手段。

因此文献资料的翻译更加需要严谨,今天知行翻译就和大家分享一下如何做好文献资料翻译。

首先,我们需要明白文献资料对于记录一个民族的历史,文化,科技,知识等多个方面具有重要作用,因此文献资料本身带有浓厚的民族气息,而且文献资料的年代都比较久远,语言文字的转化较为复杂,如果在翻译过程中使用同化翻译,难免会使文献资料失去原本的文化历史价值,因此,知行翻译觉得在翻译文献资料时,优先采用直译的方式,这样可以最大化地保证文献资料的原貌不被改动。

其次,在文献资料翻译过程中,尽量保证原文原意,前面提到文献资料的年代不定,致使文献资料所使用的的语言和现代使用的语言存在一些差距,比如我国春秋战国时期的文献资料,现代人去翻看这些文献时,也是有很大的困难,更不用说把那些复杂的句式,词汇翻译成外语了。

因此知行翻译认为在翻译文献资料时,一定要贴合愿意,如果实在无法保证,也要做好标注和解释。

再者,在文献翻译过程中,因为历史悠久,语言变化较大的原因,译员难免遇到不懂的地方,这个时候千万不能夜郎自大,刚愎自用,一定要向专业人士进行请教,然后在专业人士的指导下进行翻译,以保证文献资料的翻译质量,这一点尤为重要,因为它直接影响到文献资料的传播度。

最后,作为在翻译领域精耕细作15年的老牌翻译公司,知行翻译认为,文献资料的翻译对于一个民族,一个国家,都是具有重大意义,是向别人展示国家文化的重要途径,因此这就要求翻译人员必须对文献资料中所涉及的文化历史有一定的认知和独到的见解,只有这样才能把文献资料完整的翻译出来。

文献分析法——精选推荐

文献分析法——精选推荐

文献分析法文献分析法主要指搜集、鉴别、整理文献,并通过对文献的研究,形成对事实科学认识的方法。

文献分析法是一项经济且有效的信息收集方法,它通过对与工作相关的现有文献进行系统性的分析来获取工作信息。

一般用于收集工作的原始信息,编制任务清单初稿。

总体介绍文献分析是要弄清被分析文献“究竟讲什么”,以便给予检索标识。

一般分两步:(1)先找出文献论述的对象,再进一步查明是论述该对象哪个方面的具体问题;(2)先找出文献中涉及的各种概念,再进一步查明它们之间的关系,从而形成若干完整的主题。

从一篇文献分析出的主题数量可以是多个。

由于文献分析法和内容分析法有共同的对象,都不与文献中记载的人与事直接接触,因此,都称为非接触性研究方法。

内容分析法则通过对文献的定量分析,统计描述来实现对事实的科学认识。

二者的区别是分析的重点与分析的手段上有所不同。

2操作流程主要包括以下两个阶段::确定来源通过浏览文献的篇名、目次、摘要、引言、结论以至正文,对文献内容作调查;信息来源包括内部信息和外部信息。

(1)内部信息包括《员工手册》、《公司管理制度》、《职位职责说明》、《绩效评价》、《会议记录》、《作业流程说明》、《ISO质量文件》、《分权手册》、《工作环境描述》、《员工生产记录》、《工作计划》、《设备材料使用与管理制度》、《作业指导书》等。

(2)外部信息主要指其他企业工作分析的结果,这些资料可以为本企业的工作分析提供参照。

为了保证所收集到的信息有较强的适用性,在收集信息的时候应该注意两点:第一,目标企业应该与本企业在性质上或者行业上具有较高的相似性;第二,目标职位应该与本企业典型职位有较高的相似性。

文献分析法

文献分析法

文献分析法文献分析法是一种研究和分析学术文献的方法。

通过收集、整理和解读相关文献,研究者可以深入了解特定领域的研究状况、研究现状、研究方法和结果。

本文将介绍文献分析法的步骤和应用,以及其优缺点。

文献分析法的步骤通常包括选择研究主题、检索文献、筛选文献、整理和解读文献内容。

在选择研究主题时,研究者应该明确自己的研究目的和问题,以便更好地确定需要分析和阅读的文献类型。

然后,研究者可以通过各种途径(如数据库、图书馆等)检索相关的学术文献。

在筛选文献阶段,研究者需要仔细评估每篇文献的质量和适用性,以决定是否选择使用。

然后,研究者需要整理文献内容,将其按照主题或研究问题进行分类和组织。

最后,研究者需要仔细阅读和解读每篇文献,以了解其研究方法、实验设计和结果,并进行综合分析和总结。

文献分析法的应用广泛。

首先,它可以用于文献综述和文献调研。

研究者可以通过文献分析法了解特定领域的研究进展,为自己的研究提供理论依据和研究背景。

其次,文献分析法也可以用于比较研究。

研究者可以分析不同文献中的研究对象、研究方法和研究结果,找出异同点并进行比较。

此外,文献分析法还可以用于潜在问题的发现和研究设计的优化。

研究者可以通过分析文献中的研究方法和结果,发现研究中可能存在的问题,并提出改进方法。

最后,文献分析法也可以用于理论构建和假设生成。

研究者可以通过分析文献内容,发现新的关联和理论模型,并基于此生成新的假设。

然而,文献分析法也存在一些局限性。

首先,文献分析法依赖于现有的学术文献。

如果研究领域相对较新或研究文献有限,那么文献分析法可能无法提供足够的支持和信息。

其次,文献分析法容易受到选择性偏差的影响。

研究者可能倾向于选择支持自己观点的文献,而忽视其他可能存在的观点和研究结果。

此外,文献分析法需要研究者具备深入的文献阅读和分析能力,以正确理解和解释文献内容。

综上所述,文献分析法是一种重要的研究方法,可以通过收集、整理和解读相关文献,深入了解特定领域的研究和研究成果。

外文资料翻译The Methodology of Systems AnalysisFor a system analysis to be undertaken,someone must think there is a problem-or at least recognize the possibility that a problem exists.That is,he must be dissatisfied with the current or anticipated state of affairs and want help in discovering how to bring about a change for the better.Systems analysis can almost always provide help,even if it does no more than turn up relevant information or indicate that certain actions offer little hope of bringing about improvement.In most circumstances,the analysis may even discover a course of action that will bring about the desired change,a course that can be recognized as the advantageous and implemented by those with authority to act.Systems analysis can also be used to present factual arguments and reliable information to help win acceptance for a proposed couse of action.In addition,it can help to prevent the chosen course from being rendered ineffective by adverse interests,misinterpretations,or unanticipated problems.Although a system analysis may be carried out without a specific user or set of users in mind,such work is not likely to have much influence other than to inform public debate.Decisionmaker is assumed to be an individual who wants to make decisions as rationally as possible by taking into consideration the probable consequences of each available course of action-selecting the "best"action by balancing its cost against the extent to which it helps to achieve his objectives and possible other benefits.The analyst's basic procedure is to determine what the decisionmaker wants,search out his feasible alternatives,work out the consequences that would follow the decision to adopt each of the alternatives,and then,either rank the alternatives in terms of their consequences according to criteria specified by the decisionmaker,or present the alternatives with their consequences to the decisionmaker for ranking and choice.In reality,the decisionmaking situation is rarely so uncomplicated.Theperson for whom a study is done is ususlly but one of many participants in a decisionmaking process,and he must use the results of the analysis as evidence and argument to bring the others to his point of view before acting.In some cases the decisions cannot be separated from the managerial,organizational,and political situation in which they are made,and the model we are assuming for the decisionmaker(called the rational actor model,or model I by Allison)must be supplemented or modified by bringing in organizational and political considerations.Nevertheless,as Allison remarks,"For solving problems.a model I-style analysis provides the best first cut. Indeed,for analyzing alternatives and distinguishing the preferred proposal,there is no clear alternative to this basic framework."This is the basic,unsophisticated view of the decisionmaking situation.As an example to illustrate the basic procedure,assuming that a legislative committee wants to propose legislation to increase highway safety,it is willing to consider three alternatives:a requirement for devices to make the use of seat belts automatic,lowering the maximum speed limit and enforcing it more strictly,and establishing higher standards for issuing driver's licenses.They ask the legislative analyst to carry out a systems analysis.It is useful to consider aproblem of thes type in terms of these elements: Objectives——what the decisionmaker desires to achieve.In the example,the objective is the problem,the alternatives may be policies,strategies,designs,actions,or whatever it appears might attain the objective.In the example,although the alternatives are limited to three types, within each type there are many possibilities to consider.Consequences——the results that would ensure were the alternatives to be adopted and put into effect.In the highway safety example,if the alternative of a lower maximum speed limit with stricter enforcement were implemented,a positive consequence(abenefit)would be a lower rate of fatal highway accidents;a negative consequence(a cost)would be the need for more police officers to be hired or taken from other tasks.Criteria——rules or standards that specify in terms of consequences(orsome subset of them)how the alternatives are to be ranked in order of desirability.For example,a possible criterion might be to rank the alternatives in decreasing order of the ratio of the reduction in the annual number of fatalities from implementing the alternative to the expenditure of public funds required.Model——an abstraction,a set of assumptions about some aspect of the world,either real or imaginary,intended to clarify our view of an object,process,or problem by retaining only characteristics essential to the purpose we have in mind.It is a simplified conceptual or physical image that may be used to investigate the behavior of a system or the result of an action without altering the system or taking the action.A model is made up of factors relevant to the problem and the relations among them essential to the purpose in mind.A model may take many forms.some common types are a set of tables,a series of mathematical equations,a computer program,or merely a mental image of the situation held by someone contemplating an action.In most systems analyses explicit models are normally used for predicting both the context and environment in which the alternatives are to be implemented and their associated consequences.This is necesary because the factors are usually so numerous and their interrelations so complex that intuition and mental models are not adequate to handle the large number of factors and their intricate relations.Predicting consequences is not the only,or even the first,use of models in a system analysis.It is however,the most prominent use,for such models are likely to be elaborate and programmed for a computer,whereas many other models may be no more than well-thought through concept.In our example many different models are needed to estimate the results for the alternatives,and their consequences are of different types.In our example an early problem for the analysis is to fend a way to turn the vague goal of increased highway safety into something of a more operational character——in other words,to settle on a way to measure it .Onemeasure might be the reduction in annual number of fatalities;another might be the reduction in the annual(monetary)cost of highway accidents to the victims.Another task for the analyst is to check the alternatives for feasibility.It might turn out the alternative of automated seat belts is not feasible owing to public unacceptability.If this alternative were far superior to all the others i n increasing safety,the decisionmaker would probably want to investigate the cost and effectiveness of a campaign to change public opinion.The analyst will also want to search for and examine alternatives not on the original list——such things as better emergency ambulance service,eliminating unguarded railroad crossings,and changed car design——for these alternatives may promise increased highway safety at less cost than those on the original list,and,when presented with supporting calculations,may lead the decisionmakers to expand the list of possibilities they are welling to consider.Indeed,the discovery,invention,or design of new and better alternatives is often the real payoff from systems analysis.In predicting the results associated with the various alternatives,the analyst may have to use radically differing models or methods.A model to show the effect of improved driving skills on the number of fatalities can differ considerably from a model to predict the way a lower speed limit affects fatalities.On the other hand ,predictions for both cases may be obtained statistically from experiences in other jurisdictions with similar driving conditions.In comparing alternatives various future contexts may also have to be considered,with predictions or conjectures made about the effects of,for instance,a petroleum shortage on automobile traffic and other exogenous factors beyond the decisionmakers' control.One run-through of the set of procedures is seldom enough.Several cycles or iterations are almost always necessary to refine the first models and assumptions,and thus increase one's confidence in the outcomes.系统分析的方法进行系统分析时,人们一定认为存在某个问题,或至少应该认识到存在某个问题的可能性。
