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 …

Transportation systems are a key part of sustainable development, and they need to be
carefully evaluated to show that they have a strong impact on the target area's social …

The Maclaurin symmetric mean (MSM) and dual Maclaurin symmetric mean (DMSM)
operators are two aggregation operators to aggregate the q-rung orthopair fuzzy numbers (q …

For complex last mile problems, the parcel lockers play an important role in urban areas. So,
selecting a suitable location is very much crucial to provide optimal service and better …

Entropy measure (EM) and similarity measure (SM) are important techniques in the
environment of fuzzy set (FS) theory to resolve the similarity between two objects. The q …

The location of the electric vehicle charging station (EVCS) is the important link in the
construction of the EVCS. The optimal location of the electric vehicle directly affects the …

Supplier selection in medical instrument industries is a classical multiple attribute group
decision making (MAGDM) problem. The Pythagorean 2-tuple linguistic sets (P2TLSs) can …

In this paper, we first introduce the concept of T-spherical hesitant fuzzy set (T-SHFS) on the
basis of the combination of T-spherical fuzzy sets (T-SFSs) and hesitant fuzzy sets (HFSs) …

In intuitionistic fuzzy set and their generalizations such as Pythagorean fuzzy sets and q‐
rung orthopair fuzzy sets, ranking is not easy to define. There are several techniques …

In our current era, a new rapidly spreading pandemic disease called coronavirus disease
