A Comparative Study of Defuzzification Through a Regular Weighted Function

Fuzzy systems have gained more and more attention from researchers and practitioners in various fields. In such systems, the output represented by a fuzzy set often requires transformation into a scalar value, and this task is known as the defuzzification process. In this endeavor a new approach to the problem of defuzzification using the parametric metric between two fuzzy numbers is suggested. Some preliminary results on properties of such defuzzification are divulged herein.. Therefore, this article utilizes the concept of a parametric symmetric triangular fuzzy number, and introduces a new approach to defuzzify a fuzzy quantity. The proposed method obtains the nearest parametric symmetric triangular fuzzy number relating to a fuzzy quantity
