DEFUZZIFICATION THROUGH A NOVEL APPROACH

Fuzzy systems have gained more attention from researchers and practitioners of various fields. In such systems, the output represented by a fuzzy set sometimes needs to be transformed into a scalar value, and this task is known as the defuzzification process. Several analytic methods have been proposed for this problem, but in this paper, we suggest a new approach to the problem of defuzzification using the weighted metric between fuzzy numbers. In this study some preliminary results on properties of such defuzzification will be reported.
