In Mes Materials Management

MES (Manufacturing Execution System) is information systems that reside on the plant floor between the planning systems in offices and direct industrial controls in the production manufacturing management process , which provides real-time information about the product planning , product tracing and resource allocation for the plant floor managers . As an important kind of manufacturing management, materiel management needs a universal and effective mode of tracking and management in environment of MES. Dynamic information of workshop material is gathered at real time. MES-oriented material management can help enterprise to reduce product lifecycle, increase equipment efficiency, improve product quality, and cut production cost.Traditional materiel management is divided so that related sections become separated islands. Materiel trace is absent so that information is fed back slowly and data is scattered and redundant .To solve above problems, MES-oriented material management is presented.In this paper , Under the background of application in Space Factory and based on research Projects supported by the National Defense Basic Science Research Project research material management . Firstly , based on material management exist for problems in workshop at present. Then , base on the action thing of workshop constitute Material requirement planning (MRP) ; And then study on transferring , process state , dynamic tracking , information releasing , raw management and finished product management of problems to work in process(WIP) solve a series of problem which information lag produce and management. Thirdly , UML modeling method is used to analyze and devise the MES oriented material management , and the relation of material management and other subsystem is narrate . finally , through analyse of function, functional tree is set up , and a precise oriented prototype has been developed .
