Study On Equipment Management Decision Support System Of Online Based On B/S Mode

As the improvement of science technology and the extent of modernization, the investment cost and maintenance cost for equipments got more and more biger proportion in fixed assets and circulation funds. The importance of equipments became evident in enterprise, so equipment management was put forward to high demands, which directly affected the production and management of enterprise. As the development of enterprise information constuction, equipment management informatization became more and more important. As the main pake for agricultural implements working, Farm was also in charge of the agricultural implements management and distribution. In order to improve the use ratio of agricultural implements and management level, it was meaningful to realize modernization management of agricultural machinery equipment.Aimed at two problems in existing eqipment management system: one was not online, many were still single-machine based systems and couldn't share Internet resource, it was inconvenient to manage in different palces and the management level was quite low. Another was lack of function of assistance management, couldn't support managers with the decision making and forecasting. Therefore, it was significant and meaningful to research and develop an eqipment management system of online and with function of dicision making support. Furthermore, the system was an all-purpose one. It can not only be used in farm or agriculture machine management department, but also used in other enterprise.Based on the modern management theory, using system engineering theory, database technique and network technique, realized the function of commonality and dicision making support in this dissertation. Certainly, the system could save, organize and analyze all kinds of information about the equipment management, and some good results were obtained.The main contributions were as follows:(1) Investigated the present situation and its existing problems of the eqipment management system at home and abroad, and probed to the objective and significance of research and development of the system, finally advanced the main task of this dissertation was to develop an eqipment management system on online and with function of dicision making support.(2) Adopted Windows 2000 operation system, Internet Informatin Server 5.0, SQL Server 2000 database and C# programming language of ASP.NET to build the platform of equipment management system. Based on general analysis, made sure shree-layer structure of B/S mode as the structure of system, and analyzed function of each module detaily. Put forward to difine different type of equipments by subclass which customized by managers,and it helped to fulfill the function of commonality.(3) Based on the feature of equipment management, chose some mathiematics models to build up assistant dicision support system, such as Customer satisfaction model (using Delphi method to calculate the weight of main index), equipment type-choosing analysis module based on multi-attribute utility theory, second-hand equipment identification and assessment module. They were used to resolve some actual problem.(4) According the principle of designing module independently, the system was developed and the function of user register, login, information input, modify, query, reports formation and print, equipment rejection, perchase application, dicision making management and subclass definition was realized, and the interface of the system was also described. Successfully reach the goal of dynamic database updateing, decision-making an all-purpose management, resource sharing and so on.(5) Study of several critical technologys using in the development of system, such as three-layer structure based on B/S mode, XML technique and user authority dispensation. Finally outlooked that the system was suit for usage of most enterprise, although it need to futher improvement to accommodate advanced equipment management.
