An axiomatic definition of cardinality for finite interval-valued hesitant fuzzy sets [PDF]

open access: yes, 2015
IFSA-EUSFLAT'2015: 16th World Congress of the International Fuzzy Systems Association and 9th Conference of the European Society for Fuzzy Logic and Technlogy, July 2015, Gijón, SpainRecently, some extensions of the classical fuzzy sets are studied in ...

Generalized Ideals of BCK/BCI-Algebras Based on MQHF Soft Set with Application in Decision Making

open access: yesJournal of Mathematics, 2023
The purpose of this study is to generalize the concept of Q-hesitant fuzzy sets and soft set theory to Q-hesitant fuzzy soft sets. The Q-hesitant fuzzy set is an admirable hybrid property, specially developed by the new generalized hybrid structure of ...

Aggregation functions for typical hesitant fuzzy elements and the action of automorphisms [PDF]

open access: yes, 2016
This work studies the aggregation operators on the set of all possible membership degrees of typical hesitant fuzzy sets, which we refer to as H, as well as the action of H-automorphisms which are defined over the set of all finite non-empty subsets of ...

Hesitant fuzzy sets

open access: yesInternational Journal of Intelligent Systems, 2010
Several extensions and generalizations of fuzzy sets have been introduced in the literature, for example, Atanassov's intuitionistic fuzzy sets, type 2 fuzzy sets, and fuzzy multisets. In this paper, we propose hesitant fuzzy sets. Although from a formal

Interval Valued q- Rung Orthopair Hesitant Fuzzy Choquet Aggregating Operators in Multi-Criteria Decision Making Problems

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2022
: In this paper, we introduce Interval valued q- Rung Orthopair Hesitant fuzzy sets (IVq-ROHFS) with motivation of Interval valued pythagorean Hesitant fuzzy sets [44] as a new concept.

Decomposition theorems and extension principles for hesitant fuzzy sets [PDF]

open access: yes, 2018
We prove a decomposition theorem for hesitant fuzzy sets, which states that every typical hesitant fuzzy set on a set can be represented by a well-structured family of fuzzy sets on that set.

Fuzzy Reliability Based on Hesitant and Dual Hesitant Fuzzy Set Evaluation

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2020
In this study, we calculate hesitant and dual hesitant fuzzy reliability of linear and circular consecutive 2-out-of-4:G system from reliability function and Weibull distribution. After that, we introduced some basic methods for investigating the fuzzy reliability in the form of upper and lower membership and non- membership function having an ...

A Hesitant Soft Fuzzy Rough Set and its Applications

open access: yesIEEE Access, 2019
The difficulty of establishing a common membership degree is not because there is a margin of error or some possibility distribution values, but because there is a set of possible values.

Hesitant Bipolar-Valued Fuzzy Soft Sets and Their Application in Decision Making

open access: yesComplexity, 2020
As an extension of fuzzy sets, hesitant bipolar-valued fuzzy set is a new mathematical tool for dealing with fuzzy problems, but it still has the problem with the inadequacy of the parametric tools.

Enhancement of dronogram aid to visual interpretation of target objects via intuitionistic fuzzy hesitant sets [PDF]

open access: yes, 2019
In this paper, we address the hesitant information in enhancement task often caused by differences in image contrast. Enhancement approaches generally use certain filters which generate artifacts or are unable to recover all the objects details in images.
