摘　　要：为有效地评估电梯运行状态的安全性,提出一种综合了层次分析法、熵权法、劣化度分析法和模糊综合评价法的电梯安全运行状态评估模型。从电梯各个子系统的主要指标出发,建立电梯运行状态评估指标体系。采用层次分析法和熵权法确定指标的权重,针对指标的特性,应用相应的赋权方法,得到客观的指标权重。采用劣化度分析法对指标参数进行归一化,根据隶属度函数得到评估矩阵。以南京市某电梯为例,利用模糊综合评价法,对电梯运行状态进行评估,结果为"一般",与实际情况相符。In order to effectively evaluate the safety operational status of elevator, an evaluation model is proposedbased on the analysis hierarchy process method, entropy method, deterioration analysis and fuzzy comprehensiveevaluation theory. Based on the characteristic of each subsystem in elevator, a comprehensive evaluationindex system is established which includes four aspects, that are door system, traction system, car systemand drag system. The analysis hierarchy process method and entropy method are adopted to acquire indexweight . By applying the method of deterioration analysis, the original data is normalized, and the evaluationmatrix is obtained according to the appropriate membership function. Based on the case study of an elevator inNanjing as a sample, the comprehensive safety level of the elevator is obtained. The evaluation result indicatesthat the operation status is not excellent, and the evaluation result is close to the practical safety operation status.
