Research On Supplier Risk Evaluation Based On The Matter-element And Extension Set Theories

With the growth of the global economic integration, the main form of the market competition has transformed from the competition between traditional enterprises to that between the supply chains to which enterprises belong. Thus the supply chain management has begun to play a greatly significant role. As an important part in the supply chain management, the supplier risk management, especially the supplier risk evaluation, has attracted the attention from both the industry and the theoretical field.Under the environment mentioned above, this thesis tried to make research on the problem of supplier risk evaluation. The main contents are as follows:Based on the analysis of the research background, meaning, and current research fruits from all over the world, after the basic theory about the supplier management, risk management, common-used method for the risk evaluation and the matter-element and extension-set theories were introduced, the thesis proposed the use of the matter-element and extension-set to evaluate the supplier risk. With reference to the previous research and experts opinion, a supplier risk evaluation index system was constructed which contains5second-grade indexes and26third-grade indexes. The system covers three aspects including exterior risk of supplier, inner risk of supplier and cooperative risk; an extension-set model was established to evaluate the supplier risk. Last, the thesis made a demonstrative research with ZY Company, to evaluate the risk of supplier cooperating with ZY, by which the feasibility of the application of matter-element and extension-set theories to the supplier risk evaluation field was testified.
