Study On Planning And Control Scheme For A Kind Of Medium & Small Scale Enterprise

Along with the gradual establishment and perfection of the market economic system, especially China's entering WTO, the competition among enterprises is so fierce that the enterprise informatization has become the popular demand by diverse enterprises. The conventional application of MRP II /ERP in China mainly concentrates on large scale of enterprises. As advanced management systems, they are also much needed by a lot of medium & small scale enterprises. The operation styles and managing patterns of enterprises will vary with their scales, and different manners of enterprise management systems will also be required to fit with these variations. What's more, the design and implement of planning control scheme are the kernel and key problems of MRP , MRP II and ERP. Based on one kind of medium & small scale of equipment enterprises, all of the studies of the paper about the design of planning control system are developed.The backgrounds of this paper are firstly introduced. Nowadays main resources management systems and their planning control technique, the pervasions and integration of planning control technique, current domestic studies about the schemes of enterprises management as well as some problems confronted with the domestic studies of MRP II are pointed out. The characteristics of the management about one kind of medium & small enterprises are listed. Accordingly, the main purpose and significance are summed up. Then different schemes of planning control methods are introduced and compared, the shortcomings about using MRP or JIT exclusively are analyzed, so one strategy about the combination of MRP and JIT is raised.The levels of planning model of standard MRP II are listed , the algorithms and related conceptions are described. Then, based on the opened MRP model, the concrete structure and the way of realization of ChaoLi planning control model are presented. At last, the limitation of standard MRP II to this kind of enterprise is analyzed.Finally, by analyzing the characteristics of one kind of medium & small scale equipment enterprises and summarizing the current planning control model of ChaoLi, some solutions are presented, which including how to decide the EOQ of purchasing and hybrid Push/Pull strategic model and so on, furthermore, the algorithms in detail about these solutions are described.
