Abstract
Some membership functions which are characteristic functions of fuzzy sets are periodic due to the properties of the constituent elements of the fuzzy sets. In this study, some defects in the defuzzification of periodic membership functions on orthogonal coordinates are shown. Also, a solution in which the periodic membership function is transformed into polar coordinates is proposed. Moreover, a new defuzzification method for periodic membership functions on polar coordinates is proposed.
