Abstract: In this paper we investigate the operations "+" and "." defined for intuitionistic fuzzy sets, and, hence, for intuitionstic fuzzy pairs. We provide an alternative point of view regarding its definition which renders some of its properties evident. We also discuss the class of intuitionistic pairs obtainable from a fixed intuitionistic fuzzy pair via the operation "+" or the operation ".".
Keywords: Intuitionistic fuzzy pair, Operations over intuitionistic fuzzy sets.
