Intuitionistic fuzzy decision making is to find the suitable method for ranking alternatives
based on the provided intuitionistic fuzzy information or some related attributes. To date …

In many real-life decision making (DM) situations, the available information is vague or
imprecise. To adequately solve decision problems with vague or imprecise information …

All the extensions of ordinary fuzzy sets with three-dimensional membership functions such
as intuitionistic fuzzy sets, second type intuitionistic fuzzy sets (or Pythagorean fuzzy sets) …

By combining ideas from three-way decision and Pedrycz shadowed sets, this paper
investigates two possible solutions to the problem of constructing a shadowed set from an …

Interval operations, as currently defined, suffer from the problem of not satisfying the
conditions of global complementarity and consistency of interval fuzzy preference relations …

Hesitant fuzzy preference relation (HFPR) is an effective tool to elicit decision makers'
hesitant preference information over alternatives, and consistency analysis is of great …

Considering the important role played by overlap and grouping functions in several
applications in which associativity is not demanded, in this paper we introduce the notion of …

The hesitant fuzzy preference relation (HFPR) is a useful tool for decision makers to elicit
their preference information over a set of alternatives. In this paper, it is first proposed an …

Overlap functions are aggregation functions that express the overlapping degree between
two values. They have been used both as a conjunction in several practical problems (eg …

In this paper, we investigate a new method to handle multiple attribute group decision
making (MAGDM) problems based on combined ranking value under interval type-2 fuzzy …
