摘　　要：为识别民用航空器的安全状态,提出一种基于使用困难报告(SDR)数据的民用航空器安全性状态评价方法。分析A320机型的SDR数据,按照民用航空器系统/部件通用代码分类标准建立航空器安全性状态评价指标体系,并利用指标相关性赋权(CRITIC)法得到各指标权重;应用指标模糊分割模型和全乘比例分析多目标优化方法(MULTIMOORA)构建航空器安全性状态评价模型,并将该模型运用于实例分析。研究结果表明:SDR的发生次数大体上服从正态分布,可确定安全性状态划分标准;优势理论可对比率模型、参照点法、全乘模型的结果综合排序;最终得到的A320机型的安全性状态整体处于中等水平,这一结果与实际情况基本吻合。To identify safety status of civil aircraft,a safety status evaluation method based on SDR data was proposed.Firstly,SDR data of A320 models were analyzed,and an evaluation index system was constructed according to civil aircraft system/component code classification standards.Then,index weights were obtained by using criteria importance through intercriteria correlation(CRITIC)method.Finally,an evaluation model was constructed on the basis of index fuzzy segmentation and MULTIMOORA,and a case study was conducted by utilizing this model.The results show that the occurrence frequency of SDR generally obeys normal distribution,and classification standards of safety status can be determined.Moreover,advantage theory can comprehensively rank the results of ratio system,reference point method and full multiplicative form.Most of the safety status of A320 aircraft type are in the middle level,which is basically consistent with actual situation.
