In the traditional FMEA analysis process,the attribute values of risk factors are given directly by maintenance personnel,and small changes in the attribute values due to subjective factors can affect the final evaluation results.In order to reduce this human error and make full use of experts'expertise and experience,this paper improves the risk factor evaluation method based on the fuzzy comprehensive evalu-ation model,applying the hierarchical analysis method,and the risk priority number(RPN)ranking through the expert questionnaire,which greatly enhances the validity of FMEA analysis results.
