DEVELOPMENT OF FUZZY - CLIPS EXPERT SYSTEM

FUZZY LOGIC IS REASONING METHODOLOGY THAT HAS GROWN OUT OF ABRANCH OF FORMAL MATHEMATICS KNOWN AS FUZZY SET THEORY. IT HAS BEEN USED TO HANDLE UNCERTAINTY IN RULE-BASED SOFTWARE SYSTEMS WHERE IT IS PARTICULARLY EFFECTIVE IN CAPTURING QUALITATIVE ASPECTS OF HUMAN REASONING. MANY APPLICATIONS USING FUZZY LOGIC INFERENCE MECHANISM FOR ILL-DEFINED EXPERT SYSTEMS HAVE BEEN SUCCESSFULLY DEMONSTRATED IN JAPAN AND EUROPE. IN SPITE OF THE APPARENT POTENTIAL, THIS UNIQUE HAS NOT EXTENSIVELY USED IN NASA APPLICATIONS. A GENERAL LACK OF CONFIDENCE IN THE USE OF POWERFUL TECHNOLOGY STEMS FROM THE LACK OF ADEQUATE TOOLS TO DEVELOP SYSTEMS. WE PROPOSE TO CONSTRUCT A USER-FRIENDLY, EASY-TO-USE EXPERT SYSTEM SHELLS BY EMBEDDING THIS NEW PARADIGM INTO THE EXISTING EXPERT SYSTEM SHELL, CLIPS.
