Abstract：Aiming at the limitation of the RPN ( risk priority number ) of the failure mode&effect analysis in the quality improvement activities , a new ranking method is proposed .Firstly, by fuzzy set theory and entropy weight method , fuzzy value and subjective and objective weights of decision factors are computed . Secondly, using the improved TOPSIS method and RSR ( method) for the prioritization and classification . Then, the key terms of FMEA including improvement theme , degree of difficulty , the occurrence and po-tential for improvement are put forward and defined , with the new method verified by enterprise examples . Finally, an enterprise example verifies the availability and stability of the new ranking method .
