Knowledge and Data Representation for Circuit Pack Troubleshooting
01 January 1988
The paper discusses the design and implementation issues of automated d diagnostic and repair stations for circuit boards. It has been shown that an adoption of a control-theoretic point of view of the entire diagnostic process yields several advantages over the traditional approaches. In particular, a natural decomposition of the control system into three cooperating yet independent subsystems is obtained. At this point the techniques of Artificial Intelligence are utilized for efficient implementation of each of the subsystems. Two of the above systems are implemented using the Expert Systems methodology. The third (supervising) system is implemented as a heuristic search procedure. The paper concentrates on the overall software design and implementation issues using the paradigm of object-oriented programming.
