Communications in Computer and Information Science 80, 647-655 (2010). Summary: We study properties of interval-valued fuzzy relations, which were introduced by L. A. Zadeh in 1975. Interval-valued fuzzy set theory is a generalization of fuzzy set theory, which was introduced also by Zadeh in 1965. We examine some properties of interval-valued fuzzy relations in the context of Atanassov’s operators and decomposable operations in interval-valued fuzzy set theory.For the entire collection see [Zbl 1200.68010].
