Brief Introduction to Type-3 Fuzzy Rules

This paper suggests a study on the introduction and development in the theory of interval type-3 fuzzy system (IT3FS). It covers a) comprehensive analysis of experiments on the investigation of IT3FS, b) the structure of type-3 fuzzy numbers (T3FN) which are considered as a new generation in fuzzy logic theory, c) brief difference between type-3 fuzzy rules and other well-known approaches such as interval type-1 and type-2 fuzzy rules, d) description and importance of fuzzy rules containing with T3FN, e) some potential areas of future investigation. The theory of IT3FS still possesses unclear and unresolved problems as much as it has a great attraction. On the other hand, its practicality is very scary and requires investigation. Therefore, this article reflects the investigation and analysis of IT3FS. To ensure effectiveness of suggested method type-3-based fuzzy rules are described.
