This thesis is the continuation of a software project to develop a diagnostic expert system for the MK92 Fire Control System based on the daily system operability test (DSOT). The focus of this work is on the design and implementation of the calibration portion of the expert system using the Adept visual programming expert system shell. The calibration module is designed as a top-down hierarchy of cohesive, loosely coupled procedures. These procedures are linked through two-way links. This modular, structured design resulted in a compact system that is easy to read, modify, maintain, and test. Many of the logical troubleshooting paths are implemented using common procedures with variables, reducing application size and recognizing the expert's use of identical logic to isolate problems in different areas of the MK92 system. The calibration module fulfills the design and functional objectives set by the project team and project sponsor. Preliminary testing shows the module to be successful in MK92 DSOT calibration fault isolation.
