Today, Knowledge based systems are used for complex problem solving and are having number of successful applications. Fault diagnosis methodology is based on failure behavior and hardware of the unit under test. This methodology is considered for the present work. Fault diagnosis in a microprocessor based electronic circuit boards needs lot of empirical knowledge and expertise and is a true artificial intelligence problem. Present research work relates to artificial intelligence systems and more particularly to a fault diagnostic knowledge based system that infers a cause of failure in electronics circuit board. The basic components of systems are knowledge base, inference engine and user interface. The knowledge is represented using object-rule structures and inference mechanism is implemented using classes. Performance of object oriented approach and rule based approach is compared and diagnosed faults were validated by industrial experts.
