Interval-Valued Fuzzy Parameterized Intuitionistic Fuzzy Soft Sets and Their Applications

open access: yesCumhuriyet Science Journal, 2019
In recent years, the fuzzy sets, interval-valued fuzzysets, intuitionistic fuzzy sets and soft sets, which offer differentperspectives for the structures containing the uncertainties, have attractedthe interest of many researchers.

Quaternionic Fuzzy Sets

open access: yesAxioms, 2023
A novel concept of quaternionic fuzzy sets (QFSs) is presented in this paper. QFSs are a generalization of traditional fuzzy sets and complex fuzzy sets based on quaternions.

m-Polar Fuzzy Sets: An Extension of Bipolar Fuzzy Sets

open access: yesThe Scientific World Journal, 2014
Recently, bipolar fuzzy sets have been studied and applied a bit enthusiastically and a bit increasingly. In this paper we prove that bipolar fuzzy sets and 0,12-sets (which have been deeply studied) are actually cryptomorphic mathematical notions. Since

Intuitionistic fuzzy sets and some of their so-called extensions [PDF]

open access: yesNotes on IFS
In the present paper we investigate the relationship between intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets and some proposed extensions of fuzzy sets, intuitionistic fuzzy sets, and sets that have similar structure.

Some geometrical methods for constructing contradiction measures on Atanassov's intuitionistic fuzzy sets [PDF]

open access: yes, 2011
Trillas et al. (1999, Soft computing, 3 (4), 197–199) and Trillas and Cubillo (1999, On non-contradictory input/output couples in Zadeh's CRI proceeding, 28–32) introduced the study of contradiction in the framework of fuzzy logic because of the ...

Gradual Sets: An Approach to Fuzzy Sets

open access: yesAdvances in Fuzzy Systems, 2023
In the fuzzy theory of sets and groups, the use of α-levels is a standard to translate problems from the fuzzy to the crisp framework. Using strong α-levels, it is possible to establish a one to one correspondence which makes possible doubly, a gradual and a functorial treatment of the fuzzy theory.

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.

Fuzzy Sets

open access: yesInformation and Control, 1965
A fuzzy set is a ``set'' of elements with a continuum of ``grades of membership''. The rigorous definition is: let \(X\) be a set of objects (elements); a fuzzy set \(A\) in \(X\) is defined by a ``membership (characteristic) function'' \(f_A\), which associates with each element \(x\in X\) a real number \(f_A(x)\in [0,1]\).

Pseudo fuzzy set

open access: yesANNALS OF FUZZY MATHEMATICS AND INFORMATICS, 2017
Here a novel idea to handle imprecise or vague set viz. Pseudo fuzzy set has been proposed. Pseudo fuzzy set is a triplet of element and its two membership functions. Both the membership functions may or may not be dependent. The hypothesis is that every positive sense has some negative sense. So, one membership function has been considered as positive
