On Complex Intuitionistic Fuzzy Soft Sets with Distance Measures and Entropies

Journal of Mathematics, 2014
We introduce the concept of complex intuitionistic fuzzy soft sets which is parametric in nature. However, the theory of complex fuzzy sets and complex intuitionistic fuzzy sets are independent of the parametrization tools.

Dual Hesitant Fuzzy Sets

Journal 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 ...

Intuitionistic fuzzy Hv-ideals

International Journal of Mathematics and Mathematical Sciences, 2006
The notion of intuitionistic fuzzy sets was introduced by Atanassov as a generalization of the notion of fuzzy sets. In this paper, we apply the concept of intuitionistic fuzzy sets to Hv-rings. We introduce the notion of an intuitionistic fuzzy Hv-ideal

Interval valued intuitionistic $(S,T)$-fuzzy $H_v$-submodules

, 2006
On the basis of the concept of the interval valued intuitionistic fuzzy sets introduced by K.Atanassov, the notion of interval valued intuitionistic fuzzy $H_v$-submodules of an $H_v$-module with respect to $t$-norm $T$ and $s$-norm $S$ is given and the ...

Centroid Transformations of Intuitionistic Fuzzy Values Based on Aggregation Operators

Mathematics, 2018
Atanassov’s intuitionistic fuzzy sets extend the notion of fuzzy sets. In addition to Zadeh’s membership function, a non-membership function is also considered. Intuitionistic fuzzy values play a crucial role in both theoretical and practical

INTUITIONISTIC FUZZY SETS IN GAMMA-SEMIGROUPS [PDF]

Bulletin of the Korean Mathematical Society, 2007
We consider the intuitionistic fuzzification of the concept of several -ideals in a -semigroup S, and investigate some properties of such -ideals.

Implication functions in interval-valued fuzzy set theory [PDF]

, 2013
Interval-valued fuzzy set theory is an extension of fuzzy set theory in which the real, but unknown, membership degree is approximated by a closed interval of possible membership degrees.

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

Notes 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.

New Entropy, Similarity Measure of Intuitionistic Fuzzy Sets and their Applications in Group Decision Making [PDF]

International Journal of Computational Intelligence Systems, 2013
In this paper, we propose a new entropy measure with geometrical interpretation of intuitionistic fuzzy sets. Compared with the entropy measure provided by Szmidt and Kacprzyk, the new entropy formula in this paper can measure both fuzziness and ...
