Fuzzy Extension to the CLIPS Expert System Shell (FuzzyCLIPS)

FuzzyCLIPS is an extension of the CLIPS (C Language Integrated Production System) expert system shell from NASA. Developed by the Integrated Reasoning Group at the NRC Institute for Information Technology, the extension has been widely distributed for a number of years.

The extension enhances CLIPS by providing a fuzzy reasoning capability that is fully integrated with CLIPS facts and inference engine, allowing the representation and manipulation of fuzzy facts and rules.

FuzzyCLIPS can deal with exact, fuzzy (or inexact), and combined reasoning, allowing fuzzy and normal terms to be freely mixed in the rules and facts of an expert system. The system uses two basic inexact concepts: fuzziness and uncertainty. It provides a useful environment for developing fuzzy applications, but it requires significant effort to update and maintain as new versions of CLIPS are released.

This technology is available without cost as a non-commercial download. Make sure to download the FuzzyCLIPS technology and try it for yourself!
