General Performance And Relationship Assessment Of Supply Chains On Fuzzy Theory

Since 1980's, in the tide of world economic unification and ardent competition for market, products have showed a series of characteristics such as fast increase of new varieties and quantities and shortening of life cycle, as well as customers become more particular at service and quality of products. To satisfy this new trend so as to improve one's market share, reduce operation cost, and in the end achieve favorable benefit, for one enterprise, traditional means such as reduction in material consumption, what is called the first profit resource, and rise in product sell, what is called the second profit resource, have less help for raising profit. So the enterprises lay more hope on fall in logistics cost, what is called the third profit resource, and therefore supply chains management is drawing much attention and become a hot point.However, increment from supply chains cannot be obtained only if all member enterprises forming a network put supply chain management into practice. Accordingly one enterprise is confronted with such a problem that how to make the single benefit of itself and the unitary benefit of the supply chain in accordance. One of the settlements is that the enterprise should transform its managing thinking. But to ensure the effect, external standards and methods should be built up to evaluate the transformation, so that the enterprise can find problem and its solution, and promote the operation of the supply chain. So effective performance assessment of supply chains is the key to supply chain management. Now, the study on general performance assessment and cooperative relation assessment is trailed.Through the analysis of similarities and differences of performance assessment of supply chains, traditional enterprises, and logistics, this file penetrated into general performance assessment and cooperative relation assessment, and put forward corresponding evaluation index and accounting methods, on the base of former evaluation means. After comparing former evaluation means, especially the structure and application of SCOR model, this file introduces multi-objective fuzzy optimal method into the field of performance assessment of supply chains, and set up multi-objective fuzzy optimization model for general performance assessment and cooperative relation assessment of supply chains.
