Diagnostic expert system for the B1B

A description is given of CEPS (CITS Expert Parameter System), one of the first large-scale applications of an expert system to upgrade a major weapon system, the B-1B strategic aircraft. CEPS is a ground-based system that augments the onboard CITS (central integrated test system) as a maintenance aid for both organizational and intermediate level technicians. Phase I of CEPS successfully demonstrated the utilization of expert system techniques for the isolation of fault ambiguities, and analysis and reduction of retest okays. Phase II consists of implementation of a prototype, including a five month period of usage by personnel at Dyess Air Force Base. Phase III will be the actual implementation of CEPS at all B-1B main operating bases.<
