On Generalized Intuitionistic Fuzzy Divergence (Relative Information) and Their Properties

Atanassov (1986) defined the notion of intuitionistic fuzzy sets, which is a generalization of the concept of fuzzy sets, introduced by the Zadeh (1965). In this paper we introduce divergence (relative information) measure, a kind of a discrimination measure, in the setting of intuitionistic fuzzy set theory. This measure is a generalized version of intuitionistic fuzzy divergence proposed by Wei and Ye (2010), having a flexibility parameter. Some properties of this measure and its applications bringing out the crucial role of the parameter in decision making problems under multicriteria are demonstrated. © 2012 World Academic Press, UK.
