Research And Implementation Of Production Management Information System In Discrete Manufacturing Enterprise

With the development of the manufacturing industry,market competition is increasingly vigorous for manufacturing companies.It needs not only advanced manufacturing technique and equipments but also advanced production management theories and ideas to raise the enterprise competition ability in domestic and international market.To face a gradually vigorous market competition,the means of choosing information-based is important to reply fierce competition.And the development and use of PMIS is in accordance with the information-based development trend of enterprise,also contributes to raising the enterprise management level.This is exactly the reason that we want to develop the PMIS.Considering the producing and operation characteristics of discrete manufacturing,a production management information system solution of automotive parts industry based on Material Requirement Planning and computer technology is proposed,which aims at the needs of customers in time and reducing overstock.The system is designed and developed,and the management of whole operation line from planning,purchasing,producing to inventory is implemented.The system mainly resolves a series of problems of part and component in the process of closed loop transfer.The contradictions of high-efficiency and low flexibility in the process of mass production,agility and low efficiency for large varieties and few quantity productions are resolved.In the paper,the situation of development about PMIS in China and abroad is summarized;the theories of MRP and system development are introduced.The system analysis according to the selfish condition is proposed.It includes problems analysis,data-flow analysis and solution.Based on the result,the functions and implements of planning management,production management,material management, inventory management and assisted management are described in detail.A brief introduction is given to the main points of database design.At the end of the paper, some run-time instants and key algorithms of allocation of quota are given.Based on the C/S structure,the system mix together the new technique of database,calculator network communication,sketch customer interface,the fourth generation search language,calculator assistance tool and portable systems etc. According to modern manufacturing technique theories and relied on the software engineering theories,it combines with "waterfall algorithm" and "spiral model". Finally,the system development of PMIS inside the enterprise is realized.This system has been put into practice and actual economic result has been obtained.
