In recent years, q-rung orthopair fuzzy sets have been appeared to deal with an increase in the value of q > 1, which allows
obtaining membership and nonmembership grades from a larger area. Practically, it covers those membership and non-
membership grades, which are not in the range of intuitionistic fuzzy sets. e hybrid form of q-rung orthopair fuzzy sets with soft
sets have emerged as a useful framework in fuzzy mathematics and decision-makings. In this paper, we presented group
generalized q-rung orthopair fuzzy soft sets (GGq-ROFSSs) by using the combination of q-rung orthopair fuzzy soft sets and
q-rung orthopair fuzzy sets. We investigated some basic operations on GGq-ROFSSs. Notably, we initiated new averaging and
geometric aggregation operators on GGq-ROFSSs and investigated their underlying properties. A multicriteria decision-making
(MCDM) framework is presented and validated through a numerical example. Finally, we showed the interconnection of our
methodology with other existing methods.
1.Introduction
Zadeh originated the fuzzy set (FS) as an enlargement of the
standard sets by the concept of inclusion of vague human
judgements in computing situations [1]. e FS is indicated
by the fuzzy information μ, which gives values from the unit
close interval [0, 1] for each prospector x ∈ X. e idea of
the FS plays an important role in the domain of soft
computing, which manages vagueness, robustness, and
partial truth. In some real-world difficulties where hu-
manoid though attains reliable and unreliable information,
the FS may not be sufficient to deal with underlying
uncertainties.
In 1986, another shape of the FS called intuitionistic
fuzzy sets (IFSs) was authorized by Atanassov, which pro-
vide a reliable grade μ(x) and unreliable grade ](x) for all x
in the universe of discourse X. e IFSs are characterized by
the sum μ(x)+ ](x) ≤ 1 and the degree of indeterminacy
π(x)� 1 − μ(x)− ](x) [2]. Xu and Yager [3, 4] discussed
the intuitionistic fuzzy value (IFV), which is an ordered pair
of reliable and unreliable information for a component in
the IFS on any x. Different rudiments of IFSs have been
established such as aggregation operators [4], similarity and
distance function [5, 6], and multicriteria decision-makings
(MCDM) [7]. e aggregation operators are imperious in
the MCDM process, which attains a shape of the measurable
information by the accumulation of big data [8–10].
e IFSs enhance FSs in a meaningful approach, which is
more capable of overcoming uncertainties, sharpless
boundaries caused by the hesitation, and lack of assurance in
human cognition. Xu and Zhao [11] extended a meaningful
and insightful view on the information synthesis for MCDM
