The aim of this paper is to define the productoperation on a family of interval valued events and the notion ofjoint interval valued observable. We show the connection betweenproduct operations for interval valued events and intuitionisticfuzzy events, too. We display the relation between joint intervalvalued observable and joint intuitionistic fuzzy observable. We...

The focus of this paper is to establish a new concept b-hybrid fuzzy contraction regarding the study fixed-point theorems in setting b-metric spaces. This idea harmonizes and refines several well-known results direction point-valued, multivalued, fuzzy-set-valued maps comparable literature. To attract researchers field, some important are shown be corollaries. Moreover, result presented suffici...

Blockchain technology is emerging and has high potential to improve transform the agricultural supply chain. This study investigates critical barriers blockchain adoption in Vietnamese chain using a novel interval-valued hesitant fuzzy Decision-Making Trial Evaluation Laboratory (IVHF-DEMATEL) approach. The IVHF-DEMATEL technique applied identify cause-and-effect relationships draw influence-re...

The main goal of this contribution is to introduce the concept of higher order hesitant fuzzy soft set as an extension of fuzzy soft set that encompasses most of the existing extensions of fuzzy soft set as special cases. Furthermore, this new concept provides us with a method for dealing with multicriteria fuzzy decision making problems which are difficult to explain in other existing extensio...

In this paper, we introduce  the notions of   interval-valued and $(in,ivq)$-interval-valued fuzzy ($p$-,$q$- and $a$-) ideals    of   BCI algebras   and investigate some of their properties.   We then derive characterization theorems for these generalized interval-valued fuzzy ideals  and discuss their relationship.

Abstract Although a single-valued neutrosophic multi-valued set (SVNMVS) can reasonably and perfectly express group evaluation information make up for the flaw of multi-valued/hesitant sets in decision-making problems, its expression methods still lack ability to process single- interval-valued hybrid information. To overcome drawbacks, this study needs propose (SIVHNMVSs), correlation coeffici...
