FuzzyCLIPS

The World's Source For Fuzzy Logic Solutions

FuzzyCLIPS offers the following functionality:

• Combines fuzzy reasoning capability with conventional rule based technology
• Retains the flexibility and portability of the CLIPS environment
• Targets development of both stand-alone and embedded systems
• Extends rule syntax and user definitions of membership function types

TIL's FuzzyCLIPS is available in 3 editions to accomodate a wide range of design and development applications:

FuzzyCLIPS Professional Edition

Designed for the advanced application developer, the FuzzyCLIPS Professional Edition provides complete capability to port the development environment and/or run-time application code to most computers with an ANSI C compiler. Developers can customize both the development and run-time delivery versions of FuzzyCLIPS by including features such as the CLIPS COOL object oriented language and adding fuzzification, fuzzy inference, and defuzzificantion functions.

The Professional packet includes the FuzzyCLIPS-Developer packet materials plus complete TIL Fuzzy processing source code for FuzzyCLIPS and a C make file for the development environment version of FuzzyCLIPS.

FuzzyCLIPS Developer Edition

Designed for the experienced application developer, the FuzzyCLIPS Developer Edition provides the capability to prepare specialized, stand-alone applications as turn-key deliverable products for DOS or Windows environments. Developers can link their own C functions into the executable code or embed the FuzzyCLIPS application as a subroutine in a larger program.

The Developer packet includes the FuzzyCLIPS User packet materials plus full CLIPS 5.1 source and executable files, a run-time library of TIL's fuzzy processing code, source code and make files for a FuzzyCLIPS run-time application example, and the source files for TIL's modifications to CLIPS.

FuzzyCLIPS User Edition

Designed for the novice application developer, the FuzzyCLIPS User Edition provides a low cost opportunity to investigate fuzzy logic technology and CLIPS rule-based expert systems. The packet provides hands-on experiences that will enable the developer to build, verify, and demonstrate sophisticated FuzzyCLIPS applications.

The User packet includes interactive executable versions of FuzzyCLIPS for DOS and Windows environments, the TIL FuzzyCLIPS User's Manual, verification and validation files, and sample FuzzyCLIPS examples.

Background

The C Language Integrated Production System (CLIPS) was developed by NASA's Johnson Space Center to specifically address the difficulty of putting state-of-the-art expert systems into practical use. CLIPS was developed in the C language to permit use of general purpose computers and to integrate smoothly with other code used in embedded applications.

FuzzyCLIPS was developed by Togai InfraLogic under a Small Business Innovation Research (SBIR) contract with NASA's Johnso Space Center to add fuzzy reasoning capability to the standard CLIPS product. This is accomplished by providing the following features:

• Three types of inference techniques:
  1. Max-Dot
  2. Max-Min
  3. Max-Av
• Three types of defuzzification techniques:
  1. Centroid
  2. Mean of Maxima
  3. Special Alpha Method (alpha value = number of rules)
• Linear, Arctan, S, Pi, Gausssian, Tsukamoto, and User-defined Membership Functions
• Save and load capability for both ASCII and binary files
• Complete C Interface
• Constructs-to-C Capability
• Portable to other ANSI-C Platforms
• Run-time Manipulation of Membership Functions, Universe of Discourse, and Rules
• Verification and Validation Utility
• Motor Control, Spacecraft Attitude Control, and Financial Analysis examples are included
