A note to the addition of fuzzy numbers based on a continuous Archimedean t-norm. (English) Zbl 0919.04010

Summary: A simple method of computing the \(T\)-sum of special types of fuzzy numbers is introduced. For the Łukasiewicz 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 \(\oplus_T\)-idempotents are studied for continuous t-norms.
