摘　　要：为了解决传统的基于规则推理(RBR)方法存在的不足,将基于案例推理(CBR)方法引入鱼雷制导故障诊断系统中。阐述了案例推理的诊断策略,重点描述了二级案例检索策略及其算法,进而从案例描述、系统结构和工作流程3个方面介绍了基于案例推理的鱼雷制导系统故障诊断方法设计,并在VB6.0平台上开发了故障诊断系统,最后通过具体的故障案例比较了RBR和CBR两种方法。案例分析结果表明,所开发的基于案例推理故障诊断系统能够提高鱼雷制导系统维修的准确性和高效性。To overcome the shortcomings of traditional rule-based reasoning（RBR）,this study introduced case-based reasoning（CBR） into torpedo guidance fault diagnosis system.The diagnosis strategy of CBR was analyzed,and the two-level case retrieval mechanism and the algorithm were explained.The design of the torpedo guidance fault diagnosis system based on CBR was particularly described from three aspects,i.e.,description of case,structure of diagnosis sys-tem,and process of working flow.And this system was developed with VB6.0.Fault case analysis shows that the pro-posed system can enhance the efficiency and correctness of fault diagnosis of torpedo guidance system.
