9、eaning of the topic1.1 INTRODUCTIONTodays society is an information society, an era of knowledge economy. Since the worlds first computer ENINC (Electronic numerical integrator and calculator) appeared in the United States in 1946 to the present, the rapid development of the computer industry, the t

10、echnical indicators out of the prohibitively high, the rapid expansion of prices and software applications led to the information processing computer as the symbol of the computer revolution, followed by global information network universal and global information sharing as a symbol of the global in

11、formation network revolution is booming. Visible, the world has entered the era of fierce competition in the field of computer information management, computers have become common, no longer ordinary tools, as we can not do without bicycles, cars. We should recognize that those who have more knowled

12、ge, information, information processing speed, large volume, who is efficient, who will be able to remain invincible in various competitions.1.2 overview of management information systemsThe concept of management information systems (MIS) is the 1961 American J. D.GALLAGHER first proposed, is a new

13、set of management science, information science, system science and computer science is a comprehensive discipline, is the study of the whole process of information management activities in the enterprise, for effective management information, provide all kinds of management decision-making informati

14、on, supporting the modernization of enterprise management.Management information system is the information system of an enterprise. It has the functions of data processing, planning, control, prediction and decision support:(1) the use of uniform standards for processing and providing information an

15、d excluding inconsistent and incomplete data.(2) complete and timely provision is required in management and decision-makingData.(3) analyze the data by using the specified data relationView the future.(4) provide different levels of reporting to all levels of management, shortening analysis and int

16、erpreting time.(5) provide the most accurate and reliable information at the lowest possible cost and the shortest possible time so as to enable the decision-maker to select the best implementation plan to improve the economic efficiency of the enterprise.1.3 significance of material information sys

17、tem developmentInformation has become another big resource after labor, land and capital. The more information the people control, the more efficient they use the information resources, and who will have a place in all competitions, who will have more advantages.The material supply department is the

18、 bridge and link between the enterprise and the production unit, and is the material guarantee department for the normal production of the enterprise. It is precisely because the supply sector is the key transfer link, the establishment of a set of materialsManagement information system is very impo

19、rtant for how to effectively supply the production materials needed in time, quality and quantity. From the micro point of view, the establishment of a set of material management information system can speed up the turnover of materials and improve production efficiency, thus strengthening the manag

20、ement of information means, and improve the economic efficiency of the unit. Macroscopically, it conforms to the trend of social informatization and socialization, and shortens the cycle of social production.The second chapter is the study of the present situation at home and abroad2.1 foreign statu

21、s quoThe invention and application of computers are regarded as the third human beingsThe major scientific and technological revolution is a leap. The highest achievement of the past revolution is machine making machines, which is the extension of the hand, while the appearance of computers can cont

22、rol the machine by machine, which is the extension of the brain. The computer is the main tool for increasing production efficiencyAnd ways. In western countries, the development of computer systems has the following four stages:Phase I (1954-1964) electronic data processing phase (EDP). This stage

23、is based on single data processing, such as financial management, material management, payroll management, etc.The second stage (1964-1974) management information system phase (MIS). During this period, due to the high speed processor and memory devices, high speed and high capacity of a breakthroug

24、h, the computer application system from the individual application of EDP to the development of multi-function, multi-level, comprehensive application stage, the MIS has become more mature, control, prediction, and assistant decision-making function.The third stage (1974-1980) decision support syste

25、m phase (DSS). At this stage, the main solutions are high-level management, large-scale decision-making and unstructured information processing.The fourth stage (1980-) function management system phase(IMS). At this stage, the emphasis is on integrated management functions, multidimensional service

26、patterns, man-machine coordination, intelligent, integrated computer aided management functions, etc.According to statistics, at present, the United States occupies 90% in the financial accounting of the work completed by the computer; information processing 80-100% material management in project ma

27、nagement is completed by the computer; 80 - 90%; in the rapid development of computer application in the country, the computer application in the management of the economy accounted for 80%; for technical computing accounted for 8%, used in the production process control accounted for 12%; thus it c

28、an be seen that the economic management is the main field of computer application.2.2 domestic situationFor a variety of reasons, the level of information resources construction in China lags far behind the level of information infrastructure construction. For a long time, the development and manage

29、ment of information resources in our country has not been synchronized with the growth of information resources. China has rich original information resources, butOn this basis, the regeneration of the two information systems and database industry scale and market share, utilization rate is quite lo

30、w, a large number of valuable information can not be further processed into commodities, value-added. The computer applications in our country are behind the western countries for more than ten years. The development and application of management information system started in 1973, and 83 years late

31、r, a great deal of practical research and development work has been started. Therefore,The development and utilization of information resources has been established as the core of national economy, information digitization, network transmission is a shortcut to narrow the gap between developing coun

32、tries and developed countries, the value of world informatization is sweeping the globe with irresistible trend, China should catch up, we must use the existing information infrastructure. The application of major development and popularization in various science and technology economy and cyber sou

33、rce database service system, in order to obtain the huge economic and social benefits.Because the material management occupy an important position in the social production, the computer in developed countries has reached more than 95%, while Chinas popularization and application of computer in manag

34、ement in the country, is at the start of the 80s. Late start, but fast development. Especially the emergence and popularization of micro computers provide a cheap and good means for information processing, and play an important role in promoting the modernization of management information processing

35、 in china. The third chapter is the main problems in material managementTechnical inspection center is established in early 1991 Juzhu two units, safety education, engineering quality, boiler and pressure vessel, measuring equipment, testing instruments and environment in the area of each unit is ma

36、inly responsible for the supervision and inspection work, derrick detection etc. The supply station is responsible for ensuring the smooth progress of the inspection and the normal supply of materials needed. Our unit supply station is directly under the four stations, materials category99 categorie

37、s, the annual throughput of 4 million 500 thousand yuan, turnover speed of 49 days, 300 thousand yuan inventory, more than a year without dynamic backlog of goods 40 thousand yuan. Supply station to report monthly monthly inventories to the supply department and the central authority bureau,Its data

38、 are collected from various books, and then statistics, and finally aggregated, and then submitted. ExistingThe main problem is:1) according to the materials submitted by each of the three units, one by oneInventory control check, carry out library level, that is, the library has its required materi

39、als, then according to the data sheet from the library to receive, and if there is no library, then notify the procurement staff procurement. There are many kinds of materials in the library, so it is very complicated and error prone.2) from the dispatch list according to monthly billing, inventory

40、is manual operation, low efficiency and Calculator Plus abacus, the accuracy is not high.Units equipped with computers are limited to typing, statements, documents can not be opened, the computer should not give full play to its functions.To solve the above problems, the leadership decided through t

41、he establishment of material management information system the material management work more standardized procedures, improve the processing speed and accuracy, but also facilitate the dynamic query, improve the level of decision-making.The fourth chapter is the solution4.1 theoretical support4.1.1

42、system construction method three principlesHuman beings have accumulated rich experience in the construction of complex engineering systems, such as energy, transportation, etc. for the purpose of studying complex systems, such as management information systemsThe scientific guiding methodology is p

43、rovided with the following principles:1) the principle of integrity. The system is a complex of elements that are interrelated and interact with each other. We must examine things from the relation of the whole and each component, from the whole, to the goal, and to the wholeFunction, and correctly

44、deal with the relationship and interaction among the components of the system.2) decomposition coordination principle.The problem is to solve complex problems into simpler ones. If the subsystem is complex, it can be subdivided. But when dealing with various sub problems, we must coordinate the beha

45、vior, function and target of each subsystem according to the whole function and target of the system, so as to ensure the realization of the whole function target.3) objective optimization principle. The principle of objective optimization, for simple systems, is to seek the optimal solution, and fo

46、r complex systems, it is a satisfactory solution. It is important to note that the principle of goal optimization is not simply a matter of seeking optimal solutionsThe most important thing to note here is that the above three principles are the three main principles for dealing with complex system

47、problems in a system approach, not all of them. In dealing with practical problems, these principles are also neededUnder the guidance, according to the characteristics of the problem, determine the specific methods and strategies for solving.4.1.2 system construction life cycle and life cycle metho

48、dAny system has its process of production, development, maturation, extinction, or renewal. This process is called the life cycle. The life cycle is the life cycle of a system is divided into several stages, and the relationship between objectives, activities, work content, working methods of each s

49、tage and each stage work made specific provisions, in order to make the construction work with scientific and rational organization and order. It is a kind of traditional management information system development method, and has been the mainstream method of large-scale system development. Steps are

50、 as follows:(1) system planning(two) system development1 system analysis, including system investigation, system feasibility study,A detailed investigation of the current system, a new system logic scheme is proposed.2 system design includes the structure design of the system, the overall function o

51、f the system design, the overall physical structure of the system design, system detailed design, database design, code design, input and output design, process design.3 system implementation, including program design, system testing and production installation disk.(three) operation and maintenance

52、 of the systemOn the whole, this system uses this life cycle method for system analysis and design.4.2, the necessity and feasibility of material management information system developmentDue to the following problems in material management:(1) according to the dispatch list, the end of the month and

53、 clearing inventories by manual operation, use a calculator or use an abacus, the work efficiency is low.(2) in the usual library, because the three units should be reported by the detailed materials and inventory books on the list of one by one comparison, the efficiency is low, but also very diffi

54、cult to manage. Therefore, it is imperative to establish a set of material management information development system. From an environmental point of view, I stood 3 486 microcomputer, 99 years on the lan. From the personnel point of view, the number of young people who have a good command of compute

55、rs will not be difficult to operate. Therefore, it is feasible to develop material management information system both economically and technically.The fifth chapter is the conception of developing material management information system5.1 system analysisThe so-called system analysis, that is, in the

56、 whole system development project, to solve what to do, the problem to solve what questionsWhat specific information requirements should be satisfied for the users to investigate and analyze clearly,Logically, or from the functional requirements of information processing, a system scheme, i.e., a lo

57、gical model, is proposed to provide the basis for the next phase of physical design and how to solve it. It is an important stage in the information development system and the first step in building the system model. Its core is target analysis and requirement analysis. Finally, the logical scheme o

58、f the system is put forward.Detailed investigation of 5.1.1 material management information systemIn the actual investigation, we mainly through the discussion, inquiry and issuing advice form, etc. to understand their demand for information systems. The main users are:(1) heads of each of the three units(2) the person in charge of each functional department of the material m
