摘要
鉴于测试序列生成专家系统知识获取困难以及知识库维护不易等问题,本文提出从案例推理技术的新角度研究CTCS-3级列控系统测试序列的生成。设计了测试序列案例推理流程;提取了现场测试序列特征属性并构建了案例的框架表示结构;为实现案例检索,设计了属性相似度计算方法、确定案例属性权重的层次分析法、案例间相似度计算方法和案例检索过程;给出一个测试序列生成的具体流程。基于案例推理的研究方法为CTCS-3级列控系统测试序列的生成提供了一个新的思路。
New case-based reasoning method was used to generate test sequence for the reason that it was difficulty to test sequence generation expert system in acquiring knowledge and maintaining the knowledge base. The paper designed the process of case based reasoning for test sequence generation, extracted the features of test sequence and constructed the framework for cases. To implement the case retrieval, it was designed the method of attribute similarity measurement, the analytic hierarchy process which was used to determine the attribute weight, method of case similarity measurement and the process of case retrieval. All example to show detailed process of test sequence generation was provided. Case-based reasoning opened up a new way to generate the test sequence.
