Representability in Interval-Valued Fuzzy Set Theory [PDF]
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2007 Interval-valued fuzzy set theory is an increasingly popular extension of fuzzy set theory where traditional [0,1]-valued membership degrees are replaced by intervals in [0,1] that approximate the (unknown) membership degrees. To construct suitable graded logical connectives in this extended setting, it is both natural and appropriate to "reuse ...

New Operations on Interval-Valued Picture Fuzzy Set, Interval-Valued Picture Fuzzy Soft Set and Their Applications [PDF]
IEEE Access, 2019 An interval-valued picture fuzzy set (IVPFS) is one of the generalizations of an interval-valued fuzzy set to handle the uncertainties in the data during analysis.

Generalised Interval‐Valued Fuzzy Soft Set [PDF]
Journal of Applied Mathematics, 2012 We introduce the concept of generalised interval‐valued fuzzy soft set and its operations and study some of their properties. We give applications of this theory in solving a decision making problem. We also introduce a similarity measure of two generalised interval‐valued fuzzy soft sets and discuss its application in a medical diagnosis problem ...

On Generalised Interval‐Valued Fuzzy Soft Sets [PDF]
Journal of Applied Mathematics, 2012 Soft set theory, initiated by Molodtsov, can be used as a new mathematical tool for dealing with imprecise, vague, and uncertain problems. In this paper, the concepts of two types of generalised interval‐valued fuzzy soft set are proposed and their basic properties are studied.

INTERVAL-VALUED FUZZY m-SEMIOPEN SETS AND INTERVAL-VALUED FUZZY m-PREOPEN SETS ON INTERVAL-VALUED FUZZY MINIMAL SPACES [PDF]
Honam Mathematical Journal, 2009 We introduce the concepts of IVF m-semiopen sets, IVF m-preopen sets, IVF m-semicontinuous mappings and IVF m-precontinuous mappings on interval-valued fuzzy minimal spaces. We investigate characterizations of IVF m-semicontinuous mappings and IVF m-precontinuous mappings and study properties of IVF m-semiopen sets and IVF m-preopen sets.

Interval-Valued H-Fuzzy Sets [PDF]
International Journal of Fuzzy Logic and Intelligent Systems, 2010 We introduce the category IVSet(H) of interval-valued H-fuzzy sets and show that IVSet(H) satisfies all the conditions of a topological universe except the terminal separator property. And we study some relations among IVSet(H), ISet(H) and Set(H).

On Interval-Valued Hesitant Fuzzy Soft Sets [PDF]
Mathematical Problems in Engineering, 2015 By combining the interval-valued hesitant fuzzy set and soft set models, the purpose of this paper is to introduce the concept of interval-valued hesitant fuzzy soft sets. Further, some operations on the interval-valued hesitant fuzzy soft sets are investigated, such as complement, “AND,” “OR,” ring sum, and ring product operations.

The α-interval valued fuzzy sets defined on α-interval valued set
Thermal Science, 2022 In this study, ?-interval valued set is defined whose elements are closed sub-intervals including ? of unit interval that is I = [0, 1]. With different order relation on this set, the properties of ?-interval valued set are examined. By the help of this order relation, it is shown that ?-interval valued set is complete lattice.

(α,β)-INTERVAL VALUED INTUITIONISTIC FUZZY SETS DEFINED ON (α,β)-INTERVAL VALUED SET
Journal of Universal Mathematics, 2023 In this paper, (α,β)-interval valued set is studied. The order relation on (α,β)-interval valued set is defined. It is shown that (α,β)-interval valued set is complete lattice by giving the definitions of infumum and supremum on these sets. Then, negation function on these sets is introduced.
