Research of Automobile Quality Fault Diagnosis Method Based on CBR

Abstract

CBR (Case-based reasoning) theory is applied to the automobile quality fault diagnosis field. Case description, case retrieve and case reuse are the main factors of CBR. It is realized by the methods of fault tree construction, discrete cases information entropy weight value calculation, discrete and multi-level semantic matching case retrieval and knowledge difference driving case reuse. The process of solving actual cases verify the validity and efficiency of CBR method in the quality fault diagnosis system.
