基于案例推理的故障诊断系统关联度计算

Case-based reasoning for the calculation of the relational degree in a faulty diagnosis system

将基于案例的推理方法应用于智能故障诊断系统中,讨论了故障案例库和结果库的建立,并将其用关系数据库的格式进行存储.应用了灰色关联理论和模糊集给出了关联度的定义和计算方法,从而可以准确地检索到相似的故障案例,对检测故障给出了定性或者定量的分析.

Casebased reasoning is applied to a faulty diagnose system. The method of building the faulty cases base and result base is discussed, and these bases are restored according to database. A method for the definition and calculation of the relational degree based on the greyrelational theory and fuzzyset theory is put forword so that similar cases can be found out accurately. A fundation is laid for future research.
