Title: New similarity measure for generalized trapezoidal fuzzy numbers:methods and applications
Abstract: Aimed at the similarity measure of fuzzy numbers,a new method to calculate similarity measure for Generalized Trapezoidal Fuzzy Numbers(GTFN)was proposed.This method can ensure the effectiveness of similarity measure,reduce complexity of computation and extend its distinguishability and application scope.Three evaluation indexes were also introduced:distinction property,inefficient rate,unreasonable rate to evaluate different similarity measures.Data showed that this proposed method gave improved performance.The method was then applied to fault diagnosis based on DS evidence theory to illustrate the proposed similarity measure being reasonable and available.
