Abstract: Two new operators over interval-valued intuitionistic fuzzy sets are introduced and their basic properties are studied. The first of them is called shrinking operator and the second one, being an extension of the first one, is called (α,β)-shrinking operator.
Keywords: Interval-valued intuitionistic fuzzy set, Operator.
