The Core Enterprise Under Supply Chain Production Planning And Control Research

Production Plan and control is one of the main matters of enterprise management. The traditional MRP/MRPII/ERP, JIT, OPT/TOC all take the single enterprise's material demand as the main core to develop, lacking of the coordination with suppliers and distributors. Therefore, the uncertainty caused by the lacks influences storage and service level greatly, and, it is also very hard for the storage control strategy to be put into play. The research of the core enterprise's production plan and control under the supply chain circumstances to be possible to fill the supply chain management theoretically insufficiency, consummates its theory and the method system, enhances our country enterprise the production management level to have the vital significance under the new market competition environment. Therefore it has the certain theory and the practical significance.Firstly, the writer defines the conception of core enterprise, and sums up the functions of it and qualifications provided with. Then the writer analyses the core enterprise's production system and the business affair flow detailed, and puts forward some possible strategies for those core enterprises, which makes a solid foundation for the research about the production plan and control model of core enterprise under the circumstances of supply chain.Secondly, aiming at the characteristics, keystones and difficulties of the core enterprise production plan, the writer brings out a general model of core enterprise's production plan under the supply chain circumstances. The writer takes a typical manufacturing enterprise which has a multilevel assembling structure under only one certain supply chain circumstance as the background, considers the restriction of the BOM structure and manufacturing ability of suppliers while designing the main production plan of core enterprise, and introduces the element of penalty to those ahead or delayed behaviors to main production plan arrangement, to set up the corresponding mathematical model and uses the genetic algorithms to this model solution.Finally, the writer establishes a kind of hierarchy structure model of the core enterprise's production process supervision under the supply chain circumstance in...
