Research On Production Management Information System In Engineering Machinery Plant Of Big River Xin Da Vehicle Limited Corporation

In the essay, it mainly makes scientific information system applying researches on production management of Engineering Machinery Plant of Big River Xin Da Vehicle Limited Corporation of Chong Qin. This information system ( called PMIS in abbreviation ) is instructed by principle of MRP ,integrated with business practical management condition. It begins from the analysis of system, using a global issue to plan the system. It inquires into the way how to control inventory, and to arrange production procession plan, and to follow the whole tracks of internal spare parts and components.The article has six chapters, the first chapter elaborates the emergency and the importance for enterprise especially middle and small plant of exploiting MIS, and briefly introduces the developing survey and platform model of MIS. At the same time, it is systematical for business to open up MIS, the choice of method has large influence on system exploiting, so the paper introduces in brief the idea of combining structured system development methodologies with object oriented method. Exploiting PMIS needs supporting of Data Base Management System, the article also introduces the characters of DBMS and Visual FoxPro. It is critical for plant to utilize MRP principle to implement the system of PMIS, the thesis expounds in detail the development and applying as well as prospectof MRP in the first session. The content above as well as the instructing idea of exploiting PMIS and exploiting environment composes the first chapter.The second chapter is investigating stage of exploiting PMIS. It interprets the problem and the improving way for present production management information system, and makes use of structured analysis tool-data dictionary and data flow diagram to know the real situation of the present production management system, putting forward the goal of opening up the PMIS.The third chapter gives detailed introduction for exploiting PMIS relating to key technology. Firstly, it elaborates in detail the critical technology involving MRP principle, calculating method of MRP as well as manufacturing standard of MRP. Secondly, it expounds the merit of building three-story C/S model, and discusses the way how to construct the Intranet of Ethernet in the plant, to manage the production data, with being the front data platform in DBMS of Visual FoxPro6.0, and being the back data platform in SQL Server 7.0. In the meantime, it also introduces the front and back operating system.The fourth chapter expounds the exploiting design of the PMIS. It discusses the principle of system function design according to analysis summary and present production management system of organization, dividing the PMIS into seven subsystems, and expounding everyone's function. The seven subsystems includes three-month rolling production plan management, production controlling management, production procession plan management, semi-manufactured material management, semi-finished product management, plant in-processed product management, basic data management. Meanwhile, this session necessarily interprets database design course, input and outputdesign of PMIS, safety mechanism design and main procedure design.The fifth chapter demonstrates running practical example of PMIS. The example shows the entrance to the windows of system. When the password is input successfully, the main menu of production management information system of Engineering Machinery Plant of Big River Xin Da Vehicle Limited Corporation of Chong Qin emerges. If you want to get the consuming quota table of spare parts and components, you can strike the menu of inquiry.The six chapter summarizes the PMIS. It makes s summary of the applying theory, critical technology as well as the settlement to the production managementThrough this paper, we can see the technology, theory requirement and the step how to construct a management information system. The system will help to bring about popularizing the information of plant, and improving management effect and level, as well as promoting the business...
