Intuitionistic Fuzzy Sets (IFS) are defined as pairs of mutually orthogonal fuzzy sets. We discuss this approach from an algebraic point of view. As a result we characterize two ...
Fuzzy relations on the same domain are classified according to the equality of families of cut sets. This equality of fuzzy relations is completely characterized, not only for un...
In this paper, we introduce four kinds of rough approximations for a given intuitionistic fuzzy set. Keywords Fuzzy set, Intuitionistic Fuzzy Set, Rough Approximations
