Fuzzy expert system shells

Abstract

For developing fuzzy control systems and fuzzy expert systems, we have several shells. We describe two shells for expert systems, FPS (Fuzzy Production System) developed by the authors and FINEST (Fuzzy Inference Environment Software with Tuning) being developed in LIFE (Laboratory for International Fuzzy Engineering Research). FPS facilitates both forward and backward fuzzy reasoning. FINEST is a GUI-based shell using an extended fuzzy reasoning method with a tuning facility and all knowledge is represented by units.<>
