In this paper, the concept of (λ, μ)-hesitant fuzzy subalgebras is introduced in Boolean algebra. Some properties are discussed. Finally, we proved that intersection and direct product two also

Every real-life optimization problem with uncertainty and hesitation can not be a single objective, consequently, class of multiobjective linear problems (MOLOP) appears in the literature. Further, experts assign values uncertain parameters, expert’s opinions about parameters are conflicting nature. There concerning methods based on fuzzy sets, or their other versions available literature that ...

An expert may experience difficulties in decision making when evaluating alternatives through a single assessment value hesitant environment. A fuzzy linear regression model (FLRM) is used for decision-making purposes, but this entirely unreasonable the presence of information. In order to overcome issue, paper, we define (HFLRM) account multicriteria (MCDM) problems The HFLRM provides an alter...

In this paper, we refine the definition of weighted hesitant fuzzy set (WHFS), the concept that allows the membership of a given element is defined in terms of several possible values together with their importance weight, and then introduce some correlation measures for WHFSs. To illustrate the application of proposed correlation measures for WHFSs, we give a practical example in medical diagn...

Moreover, Zhu et al. [11], developed dual hesitant fuzzy sets (DHFSs) as a new extension of HFSs. The DHFS is a comprehensive set encompassing several existing fuzzy sets with certain conditions, whose membership and nonmembership are represented by a set of possible values respectively. In particular cases, DHFSs can reduce to some existing fuzzy sets, such as FSs, IFSs, HFSs and FMSs. From a ...
