FMS故障诊断专家系统知识获取子系统的开发

知识获取一直是专家系统建造中的瓶颈问题,本文主要研究了专家系统的知识获取技术,提出了基于例子学习和指导学习相结合的机器学习方法,并将其应用到FMS故障诊断专家系统中,使得该专家系统在运行的过程中能够根据现场的情况不断更新和优化知识库中的知识,进一步拓宽了专家系统的应用前景.

Development of the technique of knowledge acquirement of the expert system of fault diagnosis for FMS

Knowledge acquirement is the bottleneck problem in the course of expert system founding. In this paper the technique of knowledge acquirement was studied. A method for knowledge acquirement integrating instance learning and instruction learning was proposed, and was applied to an expert system of fault diagnosis for FMS. Therefore, the rules in knowledge base can be updated and optimized while the FMS fault diagnosis expert system is running, promoting the applying foreground of the expert system of fault diagnosis for the FMS.
