The intuitionistic fuzzy (IF) set characterized by two functions was a generalization of the
fuzzy set. In this paper, we investigate multiattribute decision making (MADM) problems with …

We consider a relation between bipolar fuzzy relations (originally called intuitionistic fuzzy
relations). This relation turns out to be an equivalence in the family of all bipolar fuzzy …

The aim of this paper is to develop a new methodology for solving group decision making
problems in which preference comparisons between alternatives are expressed with …

In this paper we study properties of interval-valued fuzzy relations which were introduced by
LA Zadeh in 1975. Fuzzy set theory turned out to be a useful tool to describe situations in …

In this paper we are using intuitionistic fuzzy approach to minimize search domain in an
accidental case where the data collected for investigation is intuitionistic fuzzy in nature. To …

This paper introduces some concepts of interval-valued fuzzy relations and some of their
properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The …

Metaset is a new concept of set with partial membership relation. Although based on the
classical set theory, the metaset theory is directed towards computer implementations and …

In this paper, we extend the fuzzy relation equations to intuitionistic fuzzy relation equations.
The definition of intuitionistic fuzzy relation equations is proposed on the basis of theory of …

The paper deals with the problem of clustering based on intuitionistic fuzzy relations. A
heuristic method of possibilistic clustering is extended for of intuitionistic fuzzy tolerances …
