Abstract: A general inference engine for fault diagnsis is presented. Imprecise inference computationisperformed by modifying the EMYCIN method. The inference logic based on FTA andFMEA is founded, It has strong infer ence capability, well dynamics and flexibility. An instance ofthe model application is stated.

Key words: fault diagnosis inference engine, imprecise inference computation
