The 2-tuple linguistic Fermatean fuzzy set is an effective tool that combines the advantages
of the reliable 2-tuple linguistic model with Fermatean fuzzy set. We aim to develop novel …

The current study proposes the concept of 2-tuple linguistic complex q-rung orthopair fuzzy
sets (2TLC q-ROFSs) to address the uncertainty of the multi-attribute group decision making …

Intuitionistic fuzzy information aggregation plays an important part in the intuitionistic fuzzy
set theory, which has emerged to be a new research direction receiving more and more …

With respect to multiple attribute group decision making problems with linguistic information
of attribute values, a group decision analysis is proposed. Some new aggregation operators …

On account of the indeterminacy and subjectivity of decision makers (DMs) in complexity
decision-making environments, the evaluation information over alternatives presented by …

In the practical world, there commonly exist different types of multiple-attribute group
decision making (MAGDM) problems with uncertain information. Symmetry among some …

In this paper, we define some Einstein operations on trapezoidal cubic fuzzy set and
develop three arithmetic averaging operators, that is trapezoidal cubic fuzzy Einstein …

The Maclaurin symmetric mean (MSM) operator is a classical mean type aggregation
operator used in modern information fusion theory, which is suitable to aggregate numerical …

This paper aims to investigate the type of fuzzy multiple attribute group decision making
(MAGDM) where arguments being aggregated are allowed to support each other. In order to …

As a fuzzy set (FS) expansion, the hesitant fuzzy set (HFS) is successfully employed to
demonstrate circumstances where it is admissible to ascertain a few potential membership …
