ABSTRACT
Fuzzy set theory has been applied to complex systems that are difficult to define precisely. It is suitable in defining the ambiguous relationship between the system inputs and the desired system outputs. A fuzzy model is composed of fuzzy implications and its output is inferred by a fuzzy reasoning algorithm. According to the form of consequence in fuzzy implication, fuzzy reasoning is classified in three types: Tsukamoto fuzzy model, Mamdani fuzzy model and Sugeno fuzzy model. In this paper, we use Mamdani fuzzy model[l].
