Use of Rule Induction to Assist in the Diagnosis of Avionic Circuit Board Defects

摘要

An expert system to assist in the diagnosis of avionic circuit board faults was developed using the rule induction package Intelligence-1. The initial attempt at building an expert system failed but when the level of detail of attributes was altered an expert system was successfully built. The method was proved by building an expert system for a second circuit board using the same approach and by reproducing the same rules for the first board using a different rule induction package, IRIS. The expert system built for the first board was evaluated for accuracy by interrogation using data from additional historical examples and for worth by monitored trials. The former show that the expert system is accurate but not complete and the latter is inconclusive.
