基于模糊贴近度和熵权的航空装备维修安全综合评价

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。

Airline Equipment Maintenance Safety Comprehensive Evaluation Based on Fuzzy Asymmetric Proximity and Entropy

Aviation equipment maintenance safety is an important factor influencing equipment flight safety.In order to improve the safety 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 and entropy.On the basis of building 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.decision 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.
