 abstract={The paper deals with sup−∗ composition of intuitionistic fuzzy relations, but its considerable part concerns properties of arbitrary fuzzy relations. At first, auxiliary properties of binary operations ∗ : [0, 1]2 → [0, 1] are completed. Next, properties of composition and dual composition of fuzzy relations are discussed. Then, the existence results for sup−∗ composition of intuitionistic fuzzy relations are presented. Finally, the above results are used for construction of semigroups and semirings of intuitionistic fuzzy relations.},
