| 摘 要： | 本文简述了案例推理和故障树诊断两种方法,提出将它们进行融合诊断的思想。一方面,将案例推理得到的、但在故障树中却不存在的底事件加入到故障树,完善了故障覆盖面;另一方面,由案例库统计得到的故障树最小割集重要度,使故障定位更精确,由故障树分析法完成的成功的诊断实例,再添加到案例库中。

| Abstract: | Two methods, Case-Based Reason (CBR) and Fault Tree Analysis (FTA) are explained and integrated in this paper for aircraft fault diagnosis. Basic events, obtaining from CBR are inserted into FTA, which was not in FTA , thus fault field is expanded; On the other hand, degree of importance for minimum cut sets is getting from case library, which can find fault more accurately, the successful diagnosis case, which is obtained by FTA, is added in case library as a case. |
