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.
