The Fault Finder expert system

An expert system called the Fault Finder, which was designed to implement fault-isolation decisions for a target system using fuzzy logic and learning techniques, is presented. The Fault Finder expert system implements fault-isolation decisions for any target system or equipment modeled by lowest replaceable units. The system is configurable to any target system´s components and topology. The target system expert enters the topology in the database and enters the fault-isolation rules in the knowledge base. The prototype implementation is designed to be a technician´s helper and stands alone
