The q-rung orthopair fuzzy set (q-ROFS), initiated by Yager, is a novel tool to dispose of
indeterminacy that considers the membership μ μ and non-membership ν ν, which satisfy the …

The COVID-19 outbreak, which emerged in China and continues to spread rapidly all over
the world, has brought with it increasing numbers of cases and deaths. Governments have …

The current study is mainly devoted to explore and extend the measurement and ranking of
alternatives according to the compromise solution under the background of 2-tuple linguistic …

Complex spherical fuzzy set, an extended version of spherical fuzzy set, is a very powerful
tool to capture fourfold information (typically yes, no, abstain and refusal), in which the range …

As a powerful generalization to intuitionistic fuzzy set (IFS), q-rung orthopair fuzzy set (q-
ROFS) is proposed by Yager, which can effectively mitigate the weakness of IFS and provide …

This research article aims at establishing the foundations of generalized hybrid frameworks
for dealing with uncertainties in knowledge-based systems. First, by combining the notions …

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

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 yield a flexible …

As a customer-driven quality improvement tool, quality function deployment (QFD) can
convert customer requirements (CRs) into appropriate engineering characteristics (ECs) in …

The q-rung orthopair fuzzy sets (q-ROFSs), originated by Yager, are good tools to describe
fuzziness in human cognitive processes. The basic elements of q-ROFSs are q-rung …
