Abstract: An survey of the existing interval-valued intuitionistic fuzzy modal operators is given. Eight new operators are introduced that extend the older ones. Some of their basic properties are discussed. Open problems are formulated.
Keywords: Interval-valued intuitionistic fuzzy set, Interval-valued intuitionistic fuzzy operator.
