The Study On Application Of Combining MRPⅡwith JIT In Manufacturing Enterprises

The aim of the research is to probing the optimum means of combining MRPâ…¡ with JIT,and to study the advanced Manufacture Management System, which is fit for the condition of our country. For this reason, the writer summarizes and analysis the backdrops to MRP and JIT, the rules of application,the means of administration,the key elements and the modes of control,the parameters of system operation, and so on , base on the tracks of study progress inward and outward. Then the writer analyses the advantages and the defects of the two management fashions, which not only supplies the theory foundation and the essentials for the research, but also clarifies some basics concept of the two kinds of production modes,and which makes us master the two kinds of production modes better,and benefits the business to apply the two kinds of modes of production.Afterwards, the writer studies the algorithm of the bottleneck working procedure base on professor Wang's theory research fruit,gives out the computational method of storage of works in production,which resolves the key issue that MRP and JIT are applied in the business practice. In the 4th chapter, the writer analyses the key elements detailed: manufacturing planning,manufacturing control,purchasing management,inventory management,which is applied in the composite control system of JIT and MRP, and discusses the problem of modifying and setting-up the parameters. In the 5th chapter, the writer sums up and analyses the problem of manufacturing industry in our country and, according to the concrete situation, points out the combining MRPII with JIT is the only way by which our country introducing the well-developed production means base on our country manufacturing industry. And then, the writer discusses the problem of applying MRPII and JIT in our country. Finally, the writer gives the demonstrated research on the backdrop of our country, which expounds the implementation step together with essentials in Manufacture Management System MRPII and JIT.
