ABSTRACT:
The present invention is directed to an expert system for diagnosing faults. The system comprises a knowledge base containing information regarding a conceptual model of the equipment under diagnosis. The system also comprises an inference engine for generating a set of symptom diagnostic rules from the information contained within the knowledge base in conjunction with user-generated inputs.
