Methods to create membership functions in fuzzy-rules in knowledge-based systems

Abstract

The paper presents the author's experiences in building complex systems with knowledge bases. The systems were worked out using the author's own method based on concurrent engineering philosophies with elements of fuzzy logic in the net environment. The accepted method ensures the following: ease of creation and verification of membership functions in situations where engineers co-operate with experts; efficiency of creating the rules in concurrent engineering; and reduced number of errors in testing the discussions path in the graphic work environment. The examples of domains and ways of creating the system with the special emphasis on the membership function are presented.
