Survey of Fault Diagnosis Based on Case Reasoning

Fault diagnosis of case-based reasoning (CBR) as a novel intelligent technology can simulate the behavior of human in solving problems to find out the resolution for new ones. This paper outlines the theoretical basis and basic principles of CBR. Further, it surveys recent research for fault diagnosis of CBR from two aspects as working process and integrated framework, the former includes representation, retrieval and reuse of cases, as well as maintenance of case-base, and the latter has CBR with rule-based reasoning, artificial neural network or multi-agent system. Finally, the paper gives the characteristics and applications for six kinds of methods to fault diagnosis, and points the future research fields.
