信息系统的组成英语作文标题，The Composition of Information Systems。
Information systems play a crucial role in the modern world, serving as the backbone of countless organizations, businesses, and institutions. Understanding the components of information systems is essential for comprehending their functionality and significance. In this essay, we will delve into the various components of information systems, their functions, and their importance in today's digital age.At its core, an information system comprises hardware, software, data, people, and processes. Each component contributes uniquely to the system's overall functionality and effectiveness.Firstly, hardware refers to the physical components of the information system, including computers, servers, networking devices, and storage devices. These hardwarecomponents provide the infrastructure necessary for processing, storing, and transmitting data and information within the system.Secondly, software encompasses the programs and applications that run on the hardware. This includes operating systems, database management systems, enterprise resource planning (ERP) software, customer relationship management (CRM) software, and various other applications tailored to specific organizational needs. Software enables users to interact with the hardware, manipulate data, and perform tasks efficiently.Thirdly, data is the lifeblood of an information system. It refers to the raw facts, figures, and observations that are collected, stored, processed, and analyzed by the system. Data can take various forms, including text, numbers, images, audio, and video. Effectively managing and utilizing data is critical for decision-making, problem-solving, and achieving organizational objectives.Fourthly, people are an indispensable component ofinformation systems. Users, stakeholders, IT professionals, and other personnel play vital roles in designing, implementing, maintaining, and using information systems effectively. Human resources are responsible for defining requirements, configuring systems, troubleshooting issues, and ensuring security and compliance.Lastly, processes refer to the procedures, workflows, and methodologies employed within the information system to accomplish tasks and achieve goals. Processes encompass everything from data entry and retrieval to system maintenance and security protocols. Efficient processes streamline operations, minimize errors, and enhance productivity within the organization.The integration of these components results in a cohesive and functional information system that supports the operations and objectives of an organization. Information systems facilitate various functions, including data collection, storage, processing, analysis, dissemination, and decision-making.One of the primary functions of information systems is to support decision-making processes at all levels of an organization. Decision support systems (DSS) provide executives, managers, and other stakeholders with timely and relevant information to make informed decisions. These systems analyze data, generate reports, and present insights to facilitate strategic planning, resource allocation, and performance evaluation.Furthermore, information systems enable organizations to streamline their operations and enhance efficiency. Enterprise resource planning (ERP) systems integrate various business processes, such as finance, human resources, supply chain management, and customer relationship management, into a single, unified platform. By automating routine tasks, optimizing workflows, and facilitating communication and collaboration, ERP systems help organizations improve productivity, reduce costs, and maintain competitiveness in the marketplace.Additionally, information systems play a crucial role in facilitating communication and collaboration bothinternally and externally. Collaboration tools, such as email, instant messaging, video conferencing, and collaborative workspaces, enable employees to communicate, share ideas, and collaborate on projects in real-time, regardless of their geographical location. This enhances teamwork, fosters innovation, and accelerates decision-making processes within the organization.Moreover, information systems contribute to the strategic positioning of organizations in the global marketplace. By leveraging technology and data analytics, organizations can gain insights into market trends, consumer behavior, and competitive dynamics. This enables them to identify opportunities, mitigate risks, and develop strategies to gain a competitive edge.In conclusion, information systems are complex and multifaceted constructs that encompass hardware, software, data, people, and processes. These components work together synergistically to support the operations, decision-making processes, and strategic objectives of organizations. In today's digital age, the effective management andutilization of information systems are essential for achieving success and maintaining competitiveness in the global marketplace.。

英⽂⽂件Establishing a management informationsystemInformation is a critical resource in the operation and management of organizations. Timely availability of relevant information is vital for effective performance of managerial functions such as planning, organizing, leading, and control. An information system in an organization is like the nervous system in the human body: it is the link that connects all the organization's components together and provides for better operation and survival in a competitive environment.The term information system usually a computer-based system, one that is designed to support the operations, management, and decision functions of an organization. Information systems in organizations thus provide information support for decision makers. Information systems encompass transaction processing systems, management information systems, decision support systems, and strategic information systems.Information consists of data that have been processed and are meaningful to a user. A system is a set of components that operate together to achieve a common purpose. Thus a management information system collects, transmits, processes, and stores data on an organization's resources, programmes, and accomplishments. The system makes possible the conversion of these data into management information for use by decision makers within the organization. A management information system, therefore, produces information that supports the management functions of an organization (Davis & Olson, 1985; Lucas, 1990; McLeod, 1995).Basic conceptsData versus InformationData refers to raw, unevaluated facts, figures, symbols, objects, events, etc. Data may be a collection of facts lying in storage, like a telephone directory or census records.Information is data that have been put into a meaningful and useful context and communicated to a recipient who uses it to make decisions. Information involves the communication and reception of intelligence or knowledge. It appraises and notifies, surprises and stimulates, reduces uncertainty, reveals additional alternatives or helps eliminate irrelevant or poor ones, and influences individuals and stimulates them to action. An element of data may constitute information in a specific context; for example, when you want to contact your friend, his or her telephone number is a piece of information; otherwise, it is just one element of data in the telephone directory.Characteristics of InformationThe characteristics of good information are relevance, timeliness, accuracy, cost-effectiveness, reliability, usability, exhaustiveness, and aggregation level. Information is relevant if it leads to improved decision making. It might also be relevant if it reaffirms a previous decision. If it does not have anything to do with your problem, it is irrelevant. For example, information about the weather conditions in Paris in January is relevant if you are considering a visit to Paris in January. Otherwise, the information is not relevant.Timeliness refers to the currency of the information presented to the users. Currency of data or information is the time gap between the occurrence of an event in the field until its presentation to the user (decision maker). When this amount of time is very short, we describe the information system as a real-time system.Accuracy is measured by comparing the data to actual events. The importance of accurate data varies with the type of decisions that need to be made. Payroll information must be exact. Approximations simply will not suffice. However, a general estimate of how much staff time was devoted to a particular activity may be all that is needed.Value of InformationInformation has a great impact on decision making, and hence its value is closely tied to the decisions that result from its use. Information does not have an absolute universal value. Its value is related to those who use it, when it is used, and in what situation it is used. In this sense, information is similar to other commodities. For example, the value of a glass of water is different for someone who has lost his way in Arctic glaciers than it is to a wanderer in the Sahara Desert.Economists distinguish value from cost or price of a commodity incurred to produce or procure the commodity. Obviously, the value of a product must be higher than its cost or price for it to be cost-effective.The concept of normative value of information has been developed by economists and statisticians and is derived from decision theory. The basic premise of the theory is that we always have some preliminary knowledge about the occurrence ofevents that are relevant to our decisions. Additional information might modify our view of the occurrence probabilities and consequently change our decision and the expected payoff from the decision. The value of additional information is, hence, the difference in expected payoff obtained by reduced uncertainty about the future event.Information supports decisions, decisions trigger actions, and actions affect the achievements or performance of the organization. If we can measure the differences in performance, we can trace the impact of information, provided that the measurements are carefully performed, the relationships among variables are well defined, and possible effects of irrelevant factors are isolated. The measured difference in performance due to informational factors is called the realistic value or revealed value of information.For most information systems, particularly those supporting middle and top management, the resulting decisions often relate to events that are not strictly defined and involve probabilities that cannot be quantified. The decision-making process often is obscure and the outcomes are scaled by multiple and incomparable dimensions. In such cases, we may either attemptto perform a multiattribute analysis or derive an overall subjective value. The subjective value reflects people's comprehensive impression of information and the amount they are willing to pay for specific information (Ahituv, Neumann, & Riley, 1994).Information as an Aid to Decision MakingSimon (1977) describes the process of decision making as comprising four steps: intelligence, design, choice, and review. The intelligence stage encompasses collection, classification, processing, and presentation of data relating to the organization and its environment. This is necessary to identify situations calling for decision. During the decision stage, the decision maker outlines alternative solutions, each of which involves a set of actions to be taken. The data gathered during the intelligence stage are now used by statistical and other models to forecast possible outcomes for each alternative. Each alternative can also be examined for technological, behavioural, and economic feasibility. In the choice stage, the decision maker must select one of the alternatives that will best contribute to the goals of the organization. Past choices can be subjected to review during implementation and monitoring to enable the manager to learn from mistakes. Information plays an important role in all four stages of the decision process.Classification of Management Information SystemsThere are various types of management information systems. Mason and Swanson (1981) describe four categories of management information systems: (1) databank information system, (2) predictive information system, (3) decision-making information system, and (4) decision-taking information system. The classification is based on the level of support that the information system provides in the process of decision making. Sachdeva (1990) comprehensively presents these four types of systems:Databank Information System.The responsibility of this information system is to observe, classify, and store any item of data which might be potentially useful to the decision maker.Predictive Information System. This system moves beyond pure data collection and the determination of trends over time. Predictive information systems provide for the drawing of inferences and predictions that are relevant to decision making. If data from the above examples were to be used in this way, it is possible to obtain information useful for making predictions or for drawing inferences.Decision-Making Information System. This system goes one step further in the process of decision making and incorporates the value system of the organization or its criteria for choosing among alternatives. An extension organization's values are many and varied. They include concerns for resolving farmer problems, increasing and providing for stability of farmer incomes, and improving the quality of farm life. But they also including and providing for stability of farmer incomes, and improving the quality of farm life. But they also include an intent to provide well for staff members (training, adequate salaries, etc.) and to aid in the process of bringing about rural economic development.Decision-Taking Information System. Examples of decision-taking information systems are not usually found in an extension organization. This is a decisionsystem in which the information system and the decision maker are one and the same. Management is so confident in the assumptions incorporated in the system that it basically relegates its power to initiate action to the system itself. Airplanes carry automatic pilot systems, which are an example of a decision-taking system. Once activated, the system itself keeps the plane on course and at the proper speed and altitude (according to parameters determined by the pilot). Another example of decision-taking information systems is found in modem factory production. In automobile production, continuous inventories of parts are maintained by computer as cars move down an assembly line. Orders are placed automatically by the computer when additional parts are needed. This is done without the intervention of a manager.Role of MIS in the management of agricultural extension programmersNational agricultural extension systems, especially in developing countries, tend to be very large. For example, in India, the national agricultural extension system employs about 125,000 people. Extension managers at various levels need relevant information in order to make effective decisions. In the absence of such information, they act only on the basis of their intuition and past experience. Data that have been processed, stored, and presented properly will aid them in analysing situations and to make effective decisions.As suggested above, at every phase of the management process, managers need information in order to make effective decisions. This we call management information. It does not include purely functional information or technical information, such as packages of practices for rice or wheat cultivation. Management information is the information required by managers as they make their decisions, such as the number of extension personnel employed by category, their training requirements, career development plans, job descriptions, budgets, forecasts, benchmark surveys, reports on socioeconomic conditions of people served, and existing facilities (Ramesh Babu& Singh, 1987).Need for automationAn automated MIS system contains data just as a manual system does. It receives input, processes input, and delivers the processed input as output. Some input devices allow direct human-machine communication, while others require data to be recorded on an input medium such as a magnetizable material (specially coated plastic flexible or floppy disks and magnetic tapes). The keyboard of a workstation connected directly to a computer is an example of a direct input device. Use of automation makes it possible to store immensequantities of information, to avoid many of the errors that find their way into manual records, and to make calculations and comparisons that would be practically impossible in a manual system.Organization of a databaseData are usually generated at the field level throughtransaction-processing systems, but once the data are captured, any echelon along the organizational hierarchy may use them, provided that information requirements have been well defined, appropriate programmers have been implemented, and a means has been arranged for the sharing of the data. This would imply that the same data can be used by different sets of programmers; hence we distinguish between the database (a set of data) and the applications (a set of programmers). In a decision support system (DSS), this set of programmers is the model base (Keen & Morton, 1978).The term database may refer to any collection of data that might serve an organizational unit. A database on a given subject is a collection of data on that subject that observes three criteria: comprehensiveness (completeness), nonredundancy, and appropriate structure. Comprehensiveness means that all the data about the subject are actually present in the database. Nonredundancy means that each individual piece of data exists only once in the database. Appropriate structure means that the data are stored in such a way as to minimize the cost of expected processing and storage(Awad&Gotterer, 1992).The idea of a large corporate database that can be flexibly shared by several applications or model bases has been realized by means of software packages specially devised to perform such tasks. These packages, called database management systems (DBMSs), are available in the market under different trade names such as ORACLE, SYBASE, INGRES, FOXBASE, and dBASE.Database Maintenance (DB Projects)This tab contains links to the administrative modules of five locally created databases.(n3) As with e-journals, records can be added, edited, and deleted, and bulk amounts of data can be imported using delimited files.Bookmarks (Bookmarks on bar beneath the tabs)Since Hobbes displays information based on a librarian's login, we were able to add some tools that provided unique data for a given librarian. For example, each person is able to upload his or her browser bookmarks from the office computer to use at the reference desk or from home. Librarians are also able to upload liaison newsletters into Hobbes, which in turn are displayed on their HDL staff page.THE LOGIC PROGRAMMING OF HobbesLogic programming, which is based on the first-order predicate logic, has been widely used in AI applications, It is a programming style of attractive features. As logic is regarded as a formalism unifying AI, data management and programming, it is the key feature of many new generation projects, especially the FGCS. The principal idea behind logicprogramming is that an algorithm comprises two parts: a logical component and a control component. The users need only to specify in his program what to do (i.e. , the logical component ), whereas it is the responsibility of the system to exercise the control on how to do it.One of the major feature of logic programs is its non-determinisms. Compared with normal programs, logic programs are non-deterministic in two senses:(1)When several clauses match a given procedure call, the search strategy by means of which the alternative clauses are tride is not determined.(2)When several calls need to be executed in a single goal statement, the order of execution is not determined.The non-determinisms of logic programs make them suitable for AI applications (e.g., problem solving ) and potentially rich in parallelism.There is continuous effort in improving the implementation efficiency of Prolog, which is a restriction of logic programming. However, the past effort mainly focuses on interpreter-based software implementation. It is only inrecent years that Prolog oriented computer architectures are developed. The PSI-II in Japan and the PLM at Berkeley are two famous sequential Prolog machines, which are based on the WAM, a high performance compiler-based execution model for Prolog. It is estimated that the highest possible performance of a sequential Prolog machine constructed.In order to meet the demand of gigantic inference speed in AI applications, the inherent parallelisms in logic programs should be exploited. There are many sources of parallelism in logic programs, of which the major ones are the AND-parallelism, the ORparallelism and the stream parallelism. Substantial research has been carried out on parallel computation models utilizing these parallelisms.New logic programming languages suitable for parallel processing have been developed. For example, the Concurrent Prolog, the GHC, the Parlog, the Delta-prolog, etc. special architectures supporting efficient implementation of these languages have been investigated. Besides, multiprocessor systems have been constructed to greatly enhance the performance of parallel processing of logic programs and production systems.THE DATAFLOW COMPUTATION OF HobbesTraditional computers are challenged with application which require tremendously high-speed computation capability, which has led computer scientists to study non vonneumann architectures, of which the most promising one is the dataflow architecture. A dataflow computation is one in which the operations are executed in an order determined by the data interdependencies and the availability of resources. In a dataflow program, the ordering of operations is not specified by the programmer, but is that implied by the data interdependencies.Two varieties of dataflow computation can be distinguished: data-driven computations, and demand-driven computations. In a data-driven computer, an instruction can be executed as soon as the input data it requires are available. After the instruction is executed, its result is made available to the successor instructions. In a demand driven (e.g. , reduction) system, an instruction is triggered when the results produced by it are demanded by other instructions. These demands cause further demands for operands unless the operands are locally available in which case the instruction isexecuted and the results are sent back. In both of these systems, as a result of data (or demand) activated instruction execution, many instructions can become available for execution at once , and it is possible to exploit all of the parallelism in the program. It is expected that these architectures can efficiently exploit concurrency of computation on a very large scale. A number of such systems are being developed around the world. Most notably, the Japanese have chosen dataflow as the underlying architecture for their Fifth Generation Machines. Dataflow and reduction architectures hold great promise, but there are some important problems to be solved before they can be used effectively to provide large scale parallelism. One major problem of dataflow architecture is its heavy overhead. To solve the problem, proposals have been made to combine dataflow with control flow, and to exploit parallelisms at task-level.Illustrative computer-based MISA national agricultural extension system is a nationwide system managed by the national government. In India, agriculture is a state subject under the division of powers between the national and the state levels. Nevertheless, the national government supplements the financial resources of the states and provides coordination at the national level. The state's administrative machinery is divided into districts, districts into subdivisions, subdivisions into blocks. A block is a group of villages and the basic unit for the administration of an agricultural extension programmer. Data collected at the block level need to be integrated at higher administrative levels to provide an integrated view at the district and state levels to support planning, monitoring, and decision making.However, the actual design may vary with the size of the state and other considerations. An integrated database for the entire state may be supportedby a mainframe/minicomputer at the state headquarters. Suitable programmes for the analysis of data may be designed to provide an interactive decision support system at the state level. Each district and subdivision may be provided with amini/micro computer, depending on the volume of data to be handled. The computers in the districts and subdivisions may be networked with the state computer. The local data may be stored and processed in the district/subdivision, and the shared data with appropriate level of aggregation may be transmitted to the state headquarters to update the integrated database. The districts and subdivisions would have direct access to the integrated database with proper authorizations assigned to them through their passwords. The blocks may have only the input-output terminals connected to the subdivision computer to feed data to the subdivision and make on-line inquiries as and when necessary.ReferencesAhituv, N., Neumann, S., & Riley, H.

Explain the problem of the establishment and maintenance of strategic information systems.Orchids Paper Company ----- return to the right directionOrchids Paper Co.Ltd. has been a lower cost paper manufacturer which produces napkin,handkerchief paper, tissues and toilet paper for fifty years. However, in the middle of 1990s, the company lost its developmental way. To take good advantage of the prosperous economic situation in the late twentieth century in the 80's, employers began to squeeze into the ascendant private-label paper market in California (the company headquarters at that time). Unfortunately, Orchids nearly went bankrupt because of the dual pressure from the high cost strategy and the debt from leveraged buyout. At the moment, its raw material and production costs exceeded its profits from customers. Orchids were forced to file for bankruptcy in 1992 and 1995.Orchids' new management organization lead by the general manager, Mike Safe and chief financial officer Jim Swagerty decided to focus on core markets, where had value-seeking customers. They moved the company from California to Pryor, Oklahoma, where the utility costs were low (paper is a resource-intensive industries) and the company's recycled papers were salable. They used a low-cost strategy so that the firm's production capacity will be maximized when companies emphasize timely delivery and allow customers to clearly understand the implementation of their orders. Orchids target market is the span from Oklahoma to Atlanta.Before the reorganization,Orchids is well known for poor service and late delivery. The company did not implement the operating and reporting practices and the financial department can not provide timely and accurate information.Orchids installed a new manufacturing resource planning systems (MRP-Ⅱ) and a financial system. The two software management systems from the Marion Ohio can monitor and coordinate sales, Inventory and financial data. They can also provide the charts based daily operations for the company. Workers and all departments can directly access to the products and order information through a central server linked with the stored data through 25personal computers. Finance Department staff can also use this system to provide timely and accurate information about the operating capacity, transportation and the product usability. They can also answer the customers’ questions. Therefore, finance department staffs make use of the financial capabilities to do more about controlling and customer service. Because employees can easily access to ensure immediate and accurate information needed to order delivery. Orchids Company can keep operating costs low. This system also makes the management of Orchids in the absence of bloated bodies and the sharp reduction in the total number of case workers to run properly. Orchids started to make profit again and its organizational and technological changes made it win a place in the industry which has traditionally been monopolized by large companies.Orchids Paper used the information systems to get the lead in the competitive advantage by providing low-cost high service products. However, compared to the simply the technological leap, it is more important to maintain this competitive edge. Managers need to find ways to maintain this competitive advantage for many years. Specifically, managers need to face the following challenges:1. Comprehensive integration: although in the company different systems are designed to serve different levels and different departments, more and more companies discovery the benefits of integrated systems. Many companies are pursuing enterprise resource planning (ERP). However, the integrated system is difficult and costly for the different organizational levels and functions to exchange of information through the technology. Managers need to determine which level of information system needs to integrate and how much it costs.2. The ability to maintain the competitive advantage: the competitive advantage brought by the strategic information systems cannot sustain long enough to ensure long-term profitability. Competitors can also install the strategic information systems. Competitive advantage is not always maintained as the market is changing rapidly. Business and economic environment is changing also. Internet can make some of the company's competitive advantage disappear soon. Technology and customer expectations are changing as well. Classic strategic information systems, such as American Airlines SABRE computer reservation systems, ATM systems and City Bank Federal Express package tracking system are benefiting users because they are the first in their respective industries. But the competitors apply the corresponding systems later. Relying on information systems solely can not get lasting business advantage. Information system originally used in decision-making often becomes a survival tool (for each company in order to survive in the industry to take some measures), or information system or even inhibit the future success of organizations to make the necessary decisions.ORCHIDS Paper Company's experience shows that information systems are very important in support of the organization's goals and making the company in the leading role in competition. In this chapter, we introduce the functions of various information systems in the organization. Then,we present the issues of the company in the competition and the methods that the Information System provides a competitive advantage in three different commercial levels.2．1 The function of the major Information System in the organizationBecause of the different attention to different targets, different characteristics and different levels in the various departments in an organization, there are different kinds of information systems. Single system cannot provide organizations with all the required information. Figure 2-1 is a description of the methods of all kinds of information systems in the organization. In the chart, the organization is divided into strategic layer, management layer, knowledge layer and business layer. And then it is further translated into the various functions into areas such as sales, marketing, production, finance, accounting and human resources. Information System is set up to meet the requirements of different organizations.2.2.1 Four different information systemsThere are four different information systems which are used for different levels of the organization. They are business layer systems, knowledge-tier system, management system and strategic level system.Business layer supports managers’work through tracking the basic business activities and things of the organization. Basic operations are such as sales progress, cash store, payroll, customer credibility determination and plant logistics. On this level，the main purpose of the system is to answer normal questions, analyze the problem of the logistics and inventory number of the organization. What is Mr. William payment and what is the problem? To answer these questions, the information must be available and the information should be current and accurate. The examples of business layer of the information system: the system using ATM data to record the bank deposit, the system to record daily time that employees work in factories, etc.Knowledge level information systems support the employees who are working for the knowledge and data in the organization. Knowledge level information system is intended to help businesses find new knowledge. New knowledge will be integrated into enterprises and help companies control document things。

说明了对信息内容的处理，就是说信息系统不仅关心 信息设备，而且要关心信息内容。 这个定义也强调了管理信息系统的支持高层决策，中 层控制和基层运作的功能。
企业信息系统描述了企业经理的希望,梦想和现实.
现在，我们又面临了信息系统定义的挑战。许多学者在标新立异。 总想肢解，分裂管理信息系统，从而使他的小枝可以壮大。 例如最早，在70年代末，有人说管理信息系统已经过时，现在应 当提决策支持系统（Decision Support Systems, DSS), 80年代初 MIT 又提议以IT替代MIS, 这些均未能得到普遍的支持。 以后又有人以信息系统来代替管理信息系统。这种替代在美国 得到了普遍的流行。这说明了美国信息系统由于管理方面已是最应用多 的领域。所以管理信息系统就可简化为信息系统。但在中国不行。 也有人用Business Information Systems, 或BIS, 来替代。但把Business 翻译成商业，就是翻译的不合适。 今天，管理信息系统领域又出现了许多新名词，如电子商务（ECommerce)，电子企业（E-Business), 企业资源管理（Enterprises Resources Planning)等。按照管理信息系统的定义，这些都不外是管理信息系统 在新的环境下的新的表现形式。
外文文献—管理信息系统
附录Ⅰ外文资料：Management Information SystemsWriter: Raymond McLeod, Jr·George Schell ，2007Information is one of the main resources available to the manager. Information can be managed just as any other resource, and interest in this topic stem from two influences. First, business has become more complex, and second, the computer has achieved improved capabilities.Computer information is used by managers, non-managers, and persons and organizations within the firm’s environment. Managers are found on all orga nizational levels of the firm and in all business areas. Managers perform functions and play roles; to be successful and they need skill in communication and problem solving. Managers should be computer literate, but, more important, they should be information literate.It is helpful if the manager has an ability to see his or her unit as a system composed of subsystems and existing within a larger super system. The firm is a physical system, but it is managed through a conceptual system. The conceptual system consists of an information processor that transforms data into information and represents the physical resources.The first major computer application was used to process accounting data. That application was followed by four others: management information systems, decision support system, the virtual office, and knowledge-based system. All five of these applications compose the computer-based information system.What are the information resources?The first efforts to engage in information management focused on data. These efforts occurred in conjunction with widespread adoption database management systems during the 1970s and 1980s. Firms reasoned that if they managed their data by implementing computer-based DBMSs, they would, in effect, manage their information.A broader view, however, is that you can manage information by managing the resources that produce the information. In other words, rather than concentrate on the input (the data)and the output (the information), attention should also be given to the information processor that transforms the input into the output. This processor includes the hardware and software, as well an the persons who develop, operate, and use the systems. Also included are the facilities that house the resources.Main Type of Resource sThe manager managers five main type of resources:●Personnel●Material●Machines(including facilities and energy)●Money●Information(including data)The task of the manager is to manage these resources in order to use them in themost effective way. The first four resource types are tangible; they exist physically and can be touched. We use the term physical resource to describe them. The fifth resource type, information, is not valuable form what it represents. That is we use the term conceptual resource to describe information and data. Managers use conceptual resources to manage physical resources.How Information is managedIt is easy to see how a manager managers physical resources, but management applies equally well to conceptual resources. The manager ensures that the necessary raw data is gathered and then processed into usable information. He or she then ensures that appropriate individuals receive the information in the proper form at the proper time so that it can be used. Finally, the manager discard information that has outlived its usefulness and replaces it with information that is current and accurate. All of this activity-acquiring information, using it in the most effective way, and discarding it at the proper time-is called information management.Increasing Complexity of Business ActivityBusiness has always been complex, but it is more so today than ever before. All firms are subject to international economic influences and compete in a worldwide marketplace, the technology of business is becoming more complex, the time frame for taking action is shrinking, and there are social constrains.International economic influences Firms of all size are subject to economic influences that can originate anywhere in the world. Such influence can be seen in the relative values of the currencies of each nation. Buyers make purchases in those countries where their currencies have the greatest value. For example, when Mexico devalued its peso during the late 1980s, tourists decided to take their vacations there, rather than in place like Hawaii.Worldwide competition Firms no longer compete in only their own geographic area. Rather, competition exists on a worldwide scale. The effects of this competition can be seen in the imports from foreign countries. The decision by General Motors in the early 1990s to close many of its plans indicates that even industry giants are not insulated from the effects of competition which can originate anywhere in the world.Increasing complexity technology We see example of technology in business every day-barcode scanners in supermarkets, computer-based airline reservation systems, automated teller technology that we do not see-factory robots and automated merchandise storage-and-handling equipment, for example. Firms invest in this technology to perform necessary operation. Just think what would happen if the L.L.Bean mail-order operation in Maine or Harrods’s department store in London could no longer use their computer!Shrinking time frames All phases of business operations are performed more rapidly than ever before. Sales representatives engage in telemarketing to contact their customers within seconds by telephone, sale orders are transmitted electronically from one computer to another, and manufacturers schedule raw material deliveries to arrive “just in time.”Social constraints Oddly enough, not all pressures favor production; some favor nonproduction. This is true in the case of products and services that society findsundesirable. Business decisions must be based on economic factors, but social costs and payoffs must be considered as well. Plant expansion, new products, new products, new sales outlets, and similar actions must all be weighed in term of their environmental impact.Each of these influences contributes to the complexity of business.Physical systems and conceptual systemsThe business firm is a physical system, composed of physical resources. A conceptual system, on the other hand, is a system that uses conceptual resources-information and data-to represent a physical system. A conceptual system exists, for example, as mental images in the manager’s mind, as figures or lines on a sheet of paper, or in the electronic form of the computer’s storage.The computer is a physical system, but the data and information stored in it can be viewed as a conceptual system. The date and information represent one or more physical system. How the date and information are stored is unimportant. What is important is what the data and information represent. The physical system is important for what it is; the conceptual system is important for its representation of the physical system.What stimulated end-user computing?End-user computing evolved because of four main influences.●An increase in computer literacy During the early 1980s, good computereducation programs at both the college and precollege level began to have an impact. Management ranks, especially on the lower levels, began to fill with computer-literate people.●The information services backing Information specialists have always had morework than they can handle. This situation became critical during the early 1980s, when users began making demands on information services for additional systems support. Information services could not respond quickly enough, and backlogs built up. Some users had to wait two or three year for their jobs to work their way through the backlog.●Low-cost hardware During this period, the market becomes flooded withlow-cost microcomputers. Users could obtain their own hardware by placing an order at the local computer store by telephone and making payment for the petty cash fund.●Prewritten software Both hardware and software firms produced software thatwould perform basic accounting tasks as well as provide information for decision making. This prewritten software offered enhanced support and ease of use, and it enabled firms and individual users with little or no computer expertise to implement computer-based system.The combination of these four influences accounted for the explosion of end-user computing.System ElementsNot all systems have the same combination of elements, but a basic configuration is illustrated in figure 1.5. Input resources are transformed into output resources. The resources flow from the input element, through the transformation element, and to theoutput element. A control mechanism monitors the transformation process to ensure that the system meets its objectives. The control mechanism is connected to the resource flow by means of a feedback loop, which obtains information from the system output and makes it available to the control mechanism. The control mechanism compares the feedback signals to the objectives and directs signals to the input element when it is necessary to change the system operation.When this arrangement of elements is used to explain a heating system, for example, the input represents the fuel, such as natural gas or coal. Combustion is the heating process that transforms the fuel into heat-the output. The control mechanism is the thermostat, the feedback loop is the wiring that connects the thermostat to the heater, and the objective is the temperature that is dialed into the thermostat.When the system elements represent a manufacturing firm, the input resources are the raw materials, which are transformed into finished products or services by the manufacturing process. The control mechanism is the firm’s management, the objectives are the goals that the firm seeks to achieve, and the feedback loop is the flow of information both to and from management.中文译文：管理信息系统作者：Raymond McLeod, Jr·George Schell 信息是管理者可以使用的主要资源之一。

MIS管理信息系统英文全解析
外文原文Management Information SystemsIntroduction To MISWhat is "Management Information Systems (MIS)"? Field Began in Early 80s. MIS bridges the gap between end-users and technical staffs (e.g. programmers). Consider the three key words (management, information, & systems) that have significant implications.Management: Managing resources that include people, machinery (technology and computers), money, and time, etc. You have to consider three managerial factors together in MIS: effectiveness, efficiency and profitability.Effectiveness–how well a firm is pursuing a goal or objective of its business; for instance, providing quality product/service can be a business goal that is usually stated in a firm's mission statement; Management by objective (MBO), etc.Efficiency–best use of resources, a synonym ['sinənim] is productivity = output divided by input. Productivity is measured in general by a ratio of OUTPUT to INPUT. Here, output indicates revenue, market share, etc., while input indicates labor, raw materials, administrative costs, operations costs, and IT related costs.Profitability - The empirical[em'pirikəl] studies（实证研究）in the IS literature have reported that on the contrary to the management's belief, there exists no significant difference in the profitability between before and after the new IS implementation. In other words, the new IS does not make significant profitability increase. In general, the bottom line in any business is the profitability. If it does not enhance the profitability, then what is a point to go through all the trouble to develop/implement a new IS? Using IT is not the perfect solution for every business situation. Whenever a new IT or information systems (IS) are implemented, additional costs incur. They can be costs related to hardware, software, training, maintenance, etc. Therefore, the cost-benefit analysis should be conducted prior to a new systems implementation.Information：Information relates to the computer; refers to knowledge. Data are a source for the information. If the data are processed in a meaningful way, they become "information." Here, IT can contribute. Information can be extracted easily through IT (e.g. computer) if data are properly processed. Therefore, the second word in M.I.S. indicates IT or computer. Of course, information can be obtained by a primitive way such as manual sorting by a clerk. Using IT definitely outperform any other means in history, in terms of processing data.Systems：If a nice system is made, it is self-running which leads to reducing the people necessary to the business process. An approach systematically doing business systems comes from systems theory that stresses the importance of systems approach to problem solving and a structured way to control and adjust automatically. Computer programmers and software engineers/developers realized it was only way to reduce a possibility of encountering errors later in the systems development process. When you construct a new/better system for the current business operations/decision-making process, you don't want to make a computer program based on the current business way. Instead, you develop a new model after serious analysis of the current system, so later can save resource in terms of time and money by avoiding a possible mistake/error. Therefore, business process reengineering (BPR) is unthinkable without a sound understanding of systems theory/concepts.MIS is a field of science that studies on (1) how better we can manage technologies (2) how better we can design information systems, in order to enhance a firm's effectiveness, efficiency and profitability. MIS is a new subject in the last ten to fifteen years. The idea is still being researched since the concept is being evolved. A teacher's bias has a large impact on this type of subject.Classification of Specialties in MIS•Systems Planning; • Systems Development; •Systems Review and Enhancement; • Special Computer Applications Systems Planning - facilities planning, distributed processing systems, systems organization, management and staff development and training, and application of new technologies.Systems Development - feasibility study and cost benefit analysis, detailed specifications of system development, equipment selection and configuration, software procurement / technical supervision of programming, implementation assistance, documentation and user training.Systems Review and Enhancement - reevaluation of information processing requirements, complete information system productivity audits, hard-ware/software performance evaluation and fine tuning, assessment and improvement of application program efficiency, staff productivity, data processing operations, studies of testing procedures, environment, security and reliability.Special Computer Applications - production planning and scheduling, inventory control, resource allocation, transportation and distribution logistics, personnel planning and administration, project management/control, information retrieval and analysis, process control, scientific and engineering applications.Approach to MIS DesignAll modern organizations are characterized by the need for management information. However this need is met, from the simplest verbal reporting system to the most sophisticated computerized system, certain basic principles must beobserved if the information provided is to contribute to effective management. Management information must be timely, accurate and in a format that lends itself to decision making. The cost of obtaining it must not exceed its value in the decision making process.RMC believes that an information system must be designed to take account of the nature of the client's business, the structure of the organization and the managerial styles of the system users. Data to be processed should be captured once only - and preferably by those who originate it and are most familiar with it. This means that the information system must be geared by operators with minimal system training, and must facilitate input error detection and correction. Our goals in information system design are to provide maximum flexibility and growth capacity for the system while minimizing operating costs and implementation disruptions.System Performance AuditOnce established, an information system must be audited periodically to ensure that it is performing all the tasks required of it as efficiently and effectively as possible. Growth of the organization, increased volume of business, changes in the business environment, technological changes and newly conceived information requirements all place increased demands on existing information systems and often cause them to be modified or extended on an ad hoc basis. Our staff has the specialized skills and experience to perform a thorough audit on existing information systems and to recommend changes in design, equipment, software and procedures, to bring them up-to-date and to peak performance. An information system audit should be performed every three years, or when processing capacity appears to be strained and upgrading of facilities is being considered.Stages in the development of Management Information SystemsOrganizations have always had some kinds of management information systems, even if it was not recognized as such. Developments in the use of the new technology have gone through several stages.Stage 1: EDP. When computers were first introduced into organizations, they were used mainly to process data for a few business functions –usually accounting and billing. Computers were located in electronic data processing (EDP) departments, because of the specialized skills needed to operate the extensive and complex system.Stage 2: MIS. The growth of EDP departments spurred managers to focus more on planning their organiz ations’ information systems. As the EDP departments’ function expanded beyond routine processing of masses of standardized data, they began to be called management information system (MIS) departments. MIS uses data created mainly in the EDP departments and it can be developed only when there already exists such department. It does not make any changes in these data. MIS could obtain information from internal and external sources.Stage 3: DDS. Later on, when remote terminals were introduced, more than one department began to use the same system. At this stage the MIS has grown beyond a data processing role and included the provision of a number of decision support systems(DSSs). While the MIS controls routine operations using data processing methods, the DSS is seen as supporting decisions on “less routine issues” and solving “semi-structured” problems.Stage 4: ARTIFICIAL INTELLIGENCE and EXPERT SYSTEMS. One of the fastest growing areas of information technology, artificial intelligence uses the computer to simulate some of the characteristics of human thought. The term artificial intelligence(AI) means the simulation of human thought process in order to select the best mode of behavior, e. g. taking a decision or responding to a situation. Expert systems are a major application of AI. They act like a human “expert” in analysing unstructured situations. Expert systems are also called “knowledge-based” systems since they are built on a framework of known facts and responses to situations. It is believed that we are moving rapidly from industrial-based society to an information-based one. The application of computer technology to management information and decision support systems has certainly had an effect on how managers perform their tasks and on how organizations behave.The changing nature of organizations and workThe development of the IT offers enormous opportunities to improve the way in which organizations work. However, the introduction of a new technology does not lead automatically to improved performance. It might result in greater job insecurity and might cause fear from the process of adapting the workforce to the requirements and pressures of implementation of modern MIS. On the other hand, MIS made it easier to store, process and access information than ever before. Employment might be also affected through the changes in demand for more and broader skills and for fewer unskilled people. More than ever, organizations seamed to be dependent on highly skilled and motivated workforce.To benefit from their investment in new IT and MIS, firms probably need to address not only the technological environment within they operate, but also their relationships with suppliers, customers and other trading partners.As the global economy and online communities collide, more and more organizations have come to depend on collaborative technology to support distributed teamwork. Flexible working arrangements, such as part-time work, working at or from home, self-employment and flexible employment contracts might become increasingly prominent. The implementation of modern MIS might improve the firm’s competitiveness and make them more flexible, more profitable through decreasing the cost and creating possibilities for accessing new markets and customers.。

Case: Frito Lay
Frito-Lay, Inc., a snack food subsidiary of Pepsi-Cola, outfitted its 10,000-person direct store-delivery sales force with handheld terminals used while calling on the 400,000 stores that sell its 100 products. Salespeople use the terminals to enter replenishment orders and record the number of “stales” removed after their 35-day shelf life. Based on this data, a printer in the truck prints an invoice handed to the store manager as part of the day’s deliveries. Salespeople hook the terminals to telephone lines to transfer each day’s data to the company’s mainframe computers in Dallas. The system saves salespeople four or five hours of paperwork per week.

The mainframes in Dallas consolidate the data each night as part of Frito-Lay’s internal replenishment system. Requirements for that system changed drastically in the 1980s, and Frito-Lay’s regional competitors became stronger. Frito-Lay had to be able to respond quickly to a variety of competitive challenges, ranging from price changes to totally new products. Coordination between manufacturing and sales had to be much tighter because the company needed to be able to run local promotions on Thursday for a product that would have to be available on Monday.

Question:
What type(s) of information systems does the case illustrate?
Debate:
The ability of large firms to build information systems like the one in the case gives them unfair advantages over small firms that lack both the staff and money to build such systems.

The system also used a data warehouse to provide comprehensive, up-to-date data for studying sales by any combination of product, store, and time period. In South Texas, the data from this system showed an unexpected drop in sales of Tostitos tortilla chips. Research into the cause of the drop indicated that a small competitor had launched a white corn tortilla chip. Frito-Lay developed a competitive white corn product within three months and regained market share.

The Frito-Lay information system supports a range of communication and decision-making functions typically associated with different types of information systems. It is a transaction processing system because it is used to enter orders from each retailer. It can be considered a management information system or executive information system because it provides information in a readily available form for management’s use. It is a decision support system because it supports decision making by helping route drivers, customers, and managers obtain needed information in a genuinely useful form.
