Title: $Research on Application of Grey-Relational Theory in CBR
Abstract: Because of the defects of rule-based reasoning(RBR) technology,such as knowledge acquisition difficulties and poor self-learning ability,introduces case-based reasoning into fault diagnosis system,and explains the mechanism and process model of the CBR-based fault diagnosis system.It explains case expression,search mechanism,case preservation and case-based maintenance in detail,and then uses grey-relational theory in calculation of similarity degree in CBR.According to the experimental results,know that the method effectively ameliorates the case retrieval algorithm,and greatly improves the accuracy of the matching degree of fault cases and the search efficiency,and also has a good resolution.
