Abstract: This paper introduces a fault diagnosis expert system for electric control equipment of a weapon system, including its system architecture and implementing method. The expert system adopts Microsoft Access97 as the configuration form of database and DAO as the database access technique in Visual Basic6.0 environment. This paper also discusses knowledge representation method integrating general production rule with fuzzy production rule, reasoning mechanism integrating precise reasoning with fuzzy reasoning, and reasoning strategy integrating rule-based reasoning with case-based reasoning.
