The MK92 Fire Control System (FCS) is the heart of shipboard weapon systems found aboard U. S. Oliver Hazard Perry class FFGs. This system, based on 1970's technology, frequently requires extensive troubleshooting and supplemental shore-base support. A maintenance advisor expert system is being developed to assist shipboard technicians in correctly diagnosing system faults, providing expert advice concerning part replacement or further tests which should be made. Additional information provided by the expert system includes documentation references, alternate location for a part, and part numbers. Storing such information in a relational database that communicates with the expert system would greatly improve its maintainability, modifiability, and accuracy. This thesis addresses the design and implementation of a database to support the MK92 MOD 2 FCS Maintenance Advisor Expert System using Microsoft Access(TM). This database includes such functions as part and replacement information, database maintenance, and expert system support. Research revealed that the currently supported Windows(TM) interprogram communications mechanism of Dynamic Data Exchange (DDE), as supported by the current versions of Access and Softsell Adept(TM), will not adequately support the database to expert system interface requirements. Suggestions for alternative interface solutions are provided in the thesis.
