A simple new method of computing T-sum of fuzzy intervals having the same results as the sum of fuzzy intervals based on the weakest t-norm T W is introduced. This work extends that of Mesiar [Fuzzy Sets and Systems 91 (1997) 231-237] and Markova [Fuzzy Sets and Systems 91 (1997) 253-258].
A simple method of computing the T-sum of special types of fuzzy numbers is introduced. For the Lukasiewicz t-norm T L the proposed method can be applied to the addition of fuzzy numbers with convex membership functions. The classes of fuzzy numbers leading to CHARACTERS OMITTED-idempotents are studied for continuous t-norms.
