Out of several generalizations of fuzzy set theory for various objectives, the notions
introduced by Atanassov (1983) and Atanassov and Gargov (1989) in defining intuitionistic …

Interval-valued intuitionistic fuzzy (IVIF) sets are useful to deal with fuzziness inherent in
decision data and decision-making processes. The aim of this paper is to develop a …
