Pythagorean fuzzy set (PFS), proposed by Yager (2013), is a generalization of the notion of
Atanassov's intuitionistic fuzzy set, which has received more and more attention. In this …

Abstract q-rung picture fuzzy sets can handle complex fuzzy and impression information by
changing a parameter q based on the different hesitation degree, and Yager operator is a …

Spherical fuzzy sets (SFSs), recently proposed by Ashraf, is one of the most important
concept to describe the fuzzy information in the process of decision making. In SFSs the sum …

There are many aggregation operators have been defined up to date, but in this work, we
define the interval valued Pythagorean fuzzy weighted geometric (IPFWG) operator, the …

Yager's q-rung orthopair fuzzy sets (q-ROFSs), which extend Zadeh's fuzzy sets, use the
membership and nonmembership functions to describe things' vague characteristics, and …

The term “q-Rung orthopair fuzzy sets (qr OFSs)” refers to the collection of the most
differentiated ideas for expressing fuzzy data in decision-making rules. The qr OFSs can …

With respect to multiple attribute group decision making (MADM) problems in which attribute
values take the form of intuitionistic linguistic numbers, some new group decision making …

The low-carbon supply chain management is big a challenge for the researchers due to the
rapid increase in global warming and environmental concerns. With the advancement of the …

In decision making problems, complex q-rung orthopair fuzzy set is regarded as a more
practical tool than complex intuitionistic fuzzy set and q-rung orthopair fuzzy set. This paper …

In this manuscript, the technique of the generalized MULTIMOORA method is investigated
by using the concept of a T‐spherical fuzzy set (T‐SFS), which is the modified idea of a …
