As a link between classical soft sets and hesitant fuzzy sets, the notion of hesitant fuzzy soft sets is introduced and applied to a decision making problem in the papers by Babitha and John (2013) and Wang et al. (2014). The aim of this paper is to apply hesitant fuzzy soft set for dealing with several kinds of theories in BCK/BCI-algebras. The notions of hesitant fuzzy soft subalgebras and (c...

In order to be able make a good decision, we need evaluate the uncertainty information of multiple attributes different alternatives that obey normal distribution, and interrelationship among should considered in process evaluating. This paper aims propose new attribute decision-making (MADM) method, which uses aggregation operator distribution comprehensively. We firstly extended Schweizer-Skl...

Industry 4.0 has the potential of growing industrialization and, on other hand, disrupting sustainability prevailing manufacturing supply chains through inducing great challenges such as higher resource consumption that, in turn, results global warming and climate change. As a result, researchers working area sustainable chain need to make deep evaluations arising for contemplating improvement ...

Hesitant fuzzy sets are very useful to deal with group decision making problems when experts have a hesitation among several possible memberships for an element to a set. During the evaluating process in practice, however, these possible memberships may be not only crisp values in [0,1], but also interval values. In this study, we extend hesitant fuzzy sets by intuitionistic fuzzy sets and refe...

Q-rung orthopair uncertain linguistic sets (q-ROULSs) are a powerful tool for describing ambiguity and uncertainty of information. In this study, considering that in most multi-attribute group decision making (MAGDM) problems, not only the quantitative evaluation information makers but also qualitative opinions should be considered. Therefore, we develop novel MAGDM method with unknown attribut...

E-scooters globally have proven an increasingly popular form of dockless micro-mobility, while also contributing to sustainable urban transportation forms. However, some safety issues arise with e-scooter use in the cities. This study aims propose a decision-making model based on q-rung orthopair fuzzy sets for prioritizing safe operation alternative. The proposed consists two stages: weighting...

In many decision-making situations, we are not restricted to two kinds of aspects, such as membership degree or nonmembership degree, and sometimes need include the abstinence (AD). However, fuzzy set theories fail cover issues, an intuitionistic soft set, Pythagorean q-rung orthopair set. All above notions can only consider a in their structures. The spherical compensates for these drawbacks i...
