IFDIS - An Expert System for Diagnosis of Failures in Jet Aircraft Engines
Abstract
IFDIS (Interactive Fault Diagnosis and Isolation System) is being developed to aid in the isolation of faults in the F404 jet engines that are installed in the F/A-18 fighters. Existing documentation supporting troubleshooting for these engines is inflexible in the level of sophistication expected of the user and it does not explicitly use the reasoning with uncertain information which is inherent in human troubleshooting. Data, which is required for troubleshooting the F404, is currently or potentially available for computer processing from a number of sources. IFDIS will assist maintenance personnel by providing on-line access to relevant information and will perform much of the tedious interpretation of the available data. The expert knowledge embodied in some of the existing maintenance manuals has been re-expressed in a format that serves as the basis for the knowledge-base for an expert system. Expert systems techniques have been employed because they offer benefits of perspicuity, they can be developed incrementally and can cope with imprecise data. IFDIS is currently based on EMYCIN but will be reimplemented using a commercial expert system shell in the near future. Keywords: Australia.
