Research On The Evaluation For Supplier Risk Based On Rough Sets And The Fuzzy Comprehensive Evaluation

In today's global economy, more and more enterprises urgently need to find a more effective way to enhance the management level, thus to increasing the productivity. Practice has proved that supply chain management has become an effective way for the enterprises to improve their competitive. It is a more convenient platform for inter-enterprise collaboration.

The first part outlines the background and significance of this study, research status in the world, and introduce the methods and ideas describes in this study; The second part, it elaborated the concepts, content and features of the risk suppliers, describes some common methods to evaluate the risk of suppliers, then introduce details of the theoretical basis of the rough sets and fuzzy comprehensive evaluation method; The third part, describe the meaning and the establishment principles of raw materials supplier risk evaluation index system in production companies. Proposed the evaluation index system of raw materials supplier's risk in production companies. The forth part is case studies, use YJ's raw material suppliers for example, analysis risk problems of raw material suppliers in the company's, evaluate the suppliers risk by use with rough set and fuzzy comprehensive evaluation model, the results obtained to identification and analysis, then put forward proposals to reduce supplier risk; The fifth part, summarizes the contents of the text, pointing out the inadequacies of the article as well as prospects for the future work.
