摘　　要：航空装备维修安全是确保装备飞行安全的重要因素,为提高航空装备飞行的安全性,需要对航空装备维修安全进行准确评价。根据航空装备维修安全评价涉及的不确定性问题,采用模糊数学和熵理论,提出一种基于模糊贴近度和熵权的航空装备维修安全综合评价方法。在建立航空装备维修安全评价指标体系的基础上,采用熵确定各指标的权重值、加权平均算子确定综合评价集,利用非对称贴近度进行决策分析。通过对某型飞机调查数据的算例分析,确定航空装备维修安全的主要影响因素,得出该型飞机维修安全水平的评价值。Aviation equipment maintenance safety is an important factor influencing equipment flight safety. In order to improve the sat^ty of aviation equipment flight, a comprehensive evaluation of aviation equipment maintenance safety is necessary. For the fuzzy uncertainty in the process of aviation equipment maintance safety evaluation, by combining fuzzy set and theory of entropy, a comprehensive evaluation method was established based on the asymmetric proximity in fuzzy set emd entropy. On the basis of build- ing an aviation equipment maintenance safety index system, the weighing coefficients of each index were determined based on the entropy, the synthetical extimation subclass on weighted average operator, deci- sion analysis was made based on asymmetric proximity. The main factors influencing aviation equipment maintenance safety were identified by way of the data analysis of a certain aircraft.
