The Jit Environment, Procurement And Supply Chain Collaboration And Optimization Study

As information, communication and manufactory technology are promoted, customers'demand becomes more and more personalized, so company have to make the management efficient and flexible. At the same time, company have to focus on supply chain management, as only the supply chain's coordination and integration become more efficient. Focusing on the supply chain, perhaps company can adapt to environment change and response to customer's demand easily. However, procurement is just the first step of enterprise performance, only the coordination, integration and control'efficiency of the supply chain works, the whole supply system can run in line. As suppliers are not certain in the supply system, the related problems have solved in theory in this paper. How to analyze cooperation problem in supply chain? How to optimize procurement supply chain under the delivery uncertain condition? Under the supplier uncertain condition, this paper will expatiate on the suppliers matching arithmetic and simulation analysis.Firstly, this paper analyzes procurement management and then provides a new procurement classification: amount-based purchasing and time-based purchasing. It provides a theoretical basis for the model of fourth chapter, also analysis the characteristics of time-based purchase and the cost of JIT Purchasing Supply Chain.Secondly, for the problem of diagnosis and find Purchasing Supply Chain issues, established diagnosis mode for JIT Purchasing Supply Chain. Provide an effective tool to evaluate Purchasing Supply Chain for enterprise, more valuable is providing an effective method for companies to find gaps and shortcomings of themselves in the industry. This model can help companies to get continue improve power through internal, industry benchmarking and income three aspects.Thirdly, based on the SCOR Model and automotive industry background establish a JIT Purchasing Supply Chain model. Through the model analysis, gives manufacturer independent decision optimize model and order policy; supplier independent optimize model and delivery strategies; from the integrative decision perspective given Purchasing Supply Chain optimize model and order policy. Simulate the data of CAMS Company further confirmed the validity, feasibility and practicality of the model. Model can effectively reduce the total cost of purchasing supply chain14.1%, manufacturers 10% cost reduction, supplier costs down 19.8%.Finally, under procurement sources uncertain of purchasing SCM, based on two–step spell algorithm to solve the set of supplier problem. Obtained by simulation of this algorithm can efficiently solve the source uncertain problem and dramatically improve purchasing supply chain competitive advantage.For time and capability are limited, this paper only done some valuable works in so many cooperation and optimal methods. Supply chain cooperation problem based on SCOR model will be discussed in the paper. Furthermore, through purchasing order distribution supply chain would be optimized even if delivery and suppliers are uncertain.
