Dual Hesitant Fuzzy Sets [PDF]

open access: yesJournal of Applied Mathematics, 2012
In recent decades, several types of sets, such as fuzzy sets, interval-valued fuzzy sets, intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets, type 2 fuzzy sets, type 𝑛 fuzzy sets, and hesitant fuzzy sets, have been introduced and ...

A note on operations of hesitant fuzzy sets [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
In this paper, properties of operations and algebraic structures of hesitant fuzzy sets are investigated. Semilattices of hesitant fuzzy sets with union and intersection are discussed, respectively.

Extended hesitant fuzzy sets

open access: yesTechnological and Economic Development of Economy, 2016
Hesitant fuzzy sets (HFSs) are a useful tool to manage situations in which the decision makers (DMs) hesitate about several possible values for the membership to assess a variable, alternative, etc.

An integrated VIKOR–AHP method for green energy systems based on q-fractional hesitant fuzzy multi-criteria decision-making [PDF]

open access: yesScientific Reports
The q-fractional hesitant fuzzy sets (q-FHFSs) extend the conventional hesitant and intuitionistic fuzzy sets by providing a richer framework for representing uncertainty.

Correlation Measures of Dual Hesitant Fuzzy Sets [PDF]

open access: yesJournal of Applied Mathematics, 2013
The dual hesitant fuzzy sets (DHFSs) were proposed by Zhu et al. (2012), which encompass fuzzy sets, intuitionistic fuzzy sets, hesitant fuzzy sets, and fuzzy multisets as special cases. Correlation measures analysis is an important research topic.

Hesitant Fuzzy Subalgebras, Ideals and Congruences on Autometrized Algebras [version 2; peer review: 2 approved, 1 approved with reservations] [PDF]

open access: yesF1000Research
This paper introduces the study of hesitant fuzzy subalgebras of autometrized algebras, obtains some of their properties, and gives some examples. Next, we introduce the concept of the hesitant fuzzy ideal and examine some of its properties.

Convexity of hesitant fuzzy sets [PDF]

open access: yesJournal of Intelligent & Fuzzy Systems, 2018
We show that a definition of convexity based on the convexity of the score function does not guarantee preservation of convexity under intersections and provide a concept of convexity for hesitant fuzzy sets without this backdraw. We study the relationship between convex hesitant fuzzy sets and convex rough sets as their cuts.
