Despite the importance of decision-making (DM) techniques for construction of effective
decision models for supplier selection, there is a lack of a systematic literature review for it …

The necessity of dealing with uncertainty in real world problems has been a long‐term
research challenge that has originated different methodologies and theories. Fuzzy sets …

The fourth industrial revolution, also labelled Industry 4.0, was beget with emergent and
disruptive intelligence and information technologies. These new technologies are enabling …

Pythagorean fuzzy sets (PFSs) as a new generalization of fuzzy sets (FSs) can handle
uncertain information more flexibly in the process of decision making. In our real life, we also …

In commemoration of the Anniversary 25th of KnoSys we present a bibliometric analysis of
the scientific content of the journal during the period 1991–2014. This analysis shows the …

Hesitant fuzzy set (HFS), which allows the membership degree of an element to a set
represented by several possible values, is considered as a powerful tool to express …

An interval-valued hesitant fuzzy linguistic set (IVHFLS) can serve as an extension of both a
linguistic term set and an interval-valued hesitant fuzzy set. This new set combines …

In this paper, we presented another form of eight similarity measures between PFSs based
on the cosine function between PFSs by considering the degree of positive membership …

The main purpose of this paper is to investigate the relationship between the entropy, the
similarity measure and the distance measure for hesitant fuzzy sets (HFSs) and interval …

Organisations are having difficulty in determining and integrating Industry 4.0 technologies
(I4. 0T) to improve social dimensions of sustainable performance. We address this issue by …
