Abstract：In order to effectively evaluate the safety operational status of elevator,an evaluation model is proposed based on the analysis hierarchy process method,entropy method,deterioration analysis and fuzzy comprehensive evaluation theory. Based on the characteristic of each subsystem in elevator,a comprehensive evaluation index system is established which includes four aspects,that are door system,traction system,car system and drag system. The analysis hierarchy process method and entropy method are adopted to acquire index weight. By applying the method of deterioration analysis,the original data is normalized,and the evaluation matrix is obtained according to the appropriate membership function. Based on the case study of an elevator in Nanjing as a sample,the comprehensive safety level of the elevator is obtained. The evaluation result indicates that the operation status is not excellent,and the evaluation result is close to the practical safety operation status.
