This study surveys the ordered weighted averaging (OWA) operator literature using a
citation network analysis. The main goals are the historical reconstruction of scientific …

The generalized Heronian mean and geometric Heronian mean operators provide two
aggregation operators that consider the interdependent phenomena among the aggregated …

In this paper, we utilize power aggregation operators to develop some Pythagorean fuzzy
power aggregation operators: Pythagorean fuzzy power average operator, Pythagorean …

An interval-valued hesitant fuzzy linguistic set (IVHFLS) can serve as an extension of both a
linguistic term set and an interval-valued hesitant fuzzy set. This new set combines …

Inter-dependency among the decision criteria and difficulty of establishing a common
membership grade are two important issues to be addressed in multi-criteria group decision …

In this paper, we presented another form of eight similarity measures between PFSs based
on the cosine function between PFSs by considering the degree of positive membership …

As a practical approach for handling uncertainty, various fuzzy sets combined with traditional
OR (operations research) methods have found huge applications. However, the fuzzy …

The theory of hesitant fuzzy linguistic term sets (HFLTSs) is a powerful technique used to
describe hesitant situations, which are typically assessed by experts using several possible …

The necessity of dealing with uncertainty in real world problems has been a long-term
research challenge which has originated different methodologies and theories. Recently, the …

Actual existing multi-criteria decision-making (MCDM) methods yield results that may be
questionable and unreliable. These methods very often ignore the issue of uncertainty and …
