Computational Intelligence Software for Interval Type-2 Fuzzy Logic

摘要

A software tool for interval type-2 fuzzy logic is presented in this article. The software tool includes a graphical user interface for construction, edition, and observation of the fuzzy systems. The Interval Type-2 Fuzzy Logic System Toolbox (IT2FLS) has a user-friendly environment for interval type-2 fuzzy logic inference system development. Tools that cover the different phases of the fuzzy system design process, from the initial description phase, to the final implementation phase, are presented as part of the Toolbox. The Toolbox's best properties are the capacity to develop complex systems and the flexibility that permits the user to extend the availability of functions for working with type-2 fuzzy operators, linguistic variables, interval type-2 membership functions, defuzzification methods, and the evaluation of interval type-2 fuzzy inference systems. The toolbox can be used for educational and research purposes.
