Abstract Pythagorean fuzzy sets (briefly, PFSs) were created as an upgrade to intuitionistic IFSs) which helped address some problems that IFSs couldn’t solve. The definition of q-rung orthopair q-ROFS) is then declared generalize and solve PFS IFS failures. Using the concept PF $$\beta $$ β -neighborhood, Zh...

The purpose of this study is to identify the most significant issues handle brain drains provide sustainability in emerging economies. In framework, a new model has been created that consists two different stages for situation. Firstly, necessary criteria are identified based on key items balanced scorecard approach. These factors weighted by using bipolar q-rung orthopair fuzzy multi stepwise ...

With respect to multi-attribute group decision making (MAGDM) problems in which the attribute values take form of Pythagorean fuzzy numbers, a new Pythagorean fuzzy aggregation operator called Pythagorean fuzzy induced generalized ordered weighted averaging (PFIGOWA) operator is proposed. Some desirable properties and families of the proposed operator are discussed. Furthermore, based on the pr...

As general concepts of sup-hesitant fuzzy right (resp., left, interior, two-sided) ideals semigroups, the sup+α-hesitant and sup-β-hesitant are introduced their properties investigated. Then, established by sets, Łukasiewicz anti-fuzzy Pythagorean hesitant hybrid interval-valued sets cubic sets. Finally, we characterize which is intra-regular, completely regular, simple semigroups or another ty...

In recent years, q-rung orthopair fuzzy sets (q-ROFSs), a novel and rigorous generalization of the set (FS) coined by Yager in 2017, have been used to manage inexplicit indefinite information daily life with high precision greater accuracy than intuitionistic (IFSs) Pythagorean (PFSs). The characterization measure similarity between q-ROFSs is important, as they applications different areas, in...

Fermatean fuzzy sets are more powerful than sets, intuitionistic and Pythagorean in handling various problems involving uncertainty. The distance measures the non-standard frameworks have got their applicability areas such as pattern analysis, clustering, medical diagnosis, etc. Also, knowledge played a vital role computing criteria weights multicriteria decision-making problems. As there is no...
