摘　　要：针对民航飞机维修过程中故障描述对应的多种故障原因和排故方法,无法进行确定性选择问题,采用模糊综合评估理论,在统计已往维修经验数据的基础上,提出一种在各种故障原因和排故方法中进行选择的优先排序算法,进而解决了飞机故障诊断信息应用的关键问题,提高了排故速度。此评估算法已应用到民航的维修实践中。Many different causes and elimination methods for airplane faults may be met during the maintaining process, however a selection can not be made. Aiming at this problem, adopting the fuzzy theory of comprehensive evaluation and based on the statistics of former empirical data of maintenance, a priority sorting algorithm to make selection from various fault causes and elimination methods is presented. Thus, the key problem on the application of the information from airplane fault diagnosis can be solved, and the speed of eliminating fault can be improved. The evaluation algorithm has been put into the practice of airplane maintenance.
