The Research And Application Of Management And Control Of Enterprise Material Stream Based On Inventory

ERP (Enterprise Resource Planning) is a kind of advanced management thinking and management method applied to the control of production, sell, purchase and inventory. Implementing ERP can bring remarkably economic benefit for enterprise.By the guidance of ERP theory, the dissertation brings forward whole structure of implementing MIS (Management Information System), which includes some subsystems such as production. sell, purchase, inventory etc.. The dissertation discusses that inventory management is one of the key links in the implement of MIS and the base of implement of material stream management in enterprise at the same time. By expanding inventory management system in production plan, purchase plan and sell function module etc., enterprise can finally realize ERP.According to material requirement of Sichuan Electric Set Equipment Plant (for short CDCT), the dissertation has contrived the whole scheme of system, and expatiated how we developed CDCT inventory management system, and presented the integration scheme of inventor management system with other sub-systems. based on analysis of enterprise material stream. For one thing, the system mainly deals with process of the in and out inventory of enterprise material and the trackingquery of performing status of purchase, production, sell etc.. For another thing. due to the good integral relations with sub-systems of purchase, production, sell etc. and function modules of quality inspection etc., the system can help enterprise manage supply chain and material stream more efficiently. The dissertation discusses the system security in detail, besides the security of operation system and database system, the system uses a kind of new mixed encryption arithmetic that unite transposition cipher and DES arithmetic to encrypt the user code and the purview symbols. And it also uses data backup, logs management and errors disposal to protect the system data, so the system has a better security. Furthermore, the development of system adopts advanced three-tier Client/Server Structure, and the interface of programming uses new windows interface of IWI that differs with traditional windows interface of MDI and SDI, which can be conveniently operated and occupy less system resource.
