Abstract: Starting with various design and implementation issues of a rule-based expert system, this paper discusses the use of Petri nets as effective and efficient tools for shell based development of expert systems. The Petri net approach provides high level interaction with domain expert for automating the construction and maintenance of expert systems. The proposed approach is simple and provides user-friendly environment for query processing and knowledge manipulation.
