摘要
针对专家系统中知识获取的“瓶颈”问题,应用粗糙集理论建立风机故障诊断专家系统框架,并利用粗糙集的约简方法消去知识库中冗余的属性,实现了知识库的精简,有效地保持和完善了知识库的结构和性能,提高了知识获取的效率。此方法应用在风机故障诊断专家系统中,收到了良好的效果。
Aimed at the bottleneck problem of obtaining knowledge of expert system,a rough-set-based fault diagnosis expert system frame for fan is built,the knowledge base and redundancies are eliminated by using the predigest method of rough set theory.So the knowledge base is simplified.the structure and performance of the knowledge base are effectively maintained and perfected according to the method.the efficiency of obtaining knowledge is improved,This method applied in fault diagnosis expert system for fan,the favorable effect is received.
