摘要
用面向对象的知识表示方法实现案例表示,用分层组织结构完成案例库组织,采用距离相似度计算方法实现案例间的相似度的计算,提出类选、粗选、精选三步走的案例检索方法。以防空火炮的故障诊断为例,验证了快速检索方法的有效性,提高故障诊断效率。
This paper realized ease representation by the object-oriented knowledge representation approach. The case base is hierarchically organized. The case similarity is calculated by the method based on distance similarity degree. A new case retrieval strategy which consisted of three steps had been explored, and the three steps were sort selection, rough selection and accurate selection. Finally, an example in the antiaircraft artillery fault diagnosis was given, which verify the effectiveness of the rapid retrieval method, and improves the efficiency of fault diagnosis.
