REPRESENTATION THEOREM OF INTERVAL-VALUED FUZZY SET

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2006
In this paper, we introduce the concept of interval-valued nested set on the universal set X, propose two representation theorems and equivalent classification theorem of interval-valued fuzzy set. These works can be used in setting up the basic theory of interval-valued fuzzy set.

Note on Interval-Valued Fuzzy Set

International Conference on Fuzzy Systems and Knowledge Discovery, 2005
In this note, we introduce the concept of cut set of interval-valued fuzzy set and discuss some properties of cut set of interval-valued fuzzy set, propose three decomposition theorems of interval-valued fuzzy set and investigate some properties of cut set of interval-valued fuzzy set and mapping H in detail.

A Generalized p-Norm Knowledge-Based Score Function for an Interval-Valued Intuitionistic Fuzzy Set in Decision Making

IEEE transactions on fuzzy systems, 2020
This paper addresses the commonly used methods for solving multiple attribute group decision-making problems under an interval-valued intuitionistic fuzzy environment.

Interval valued intuitionistic fuzzy sets

Fuzzy Sets and Systems, 1989
The intuitionistic fuzzy sets (IFS's) of the first author [Fuzzy Sets Syst. 20, 87--96 (1986; Zbl 0631.03040)] are at each point of a given universe of discourse characterized by a pair of degrees: one for membership and the other for non-membership.

Intuitionistic Interval-Valued Fuzzy Sets

Journal of Korean Institute of Intelligent Systems, 2010
We introduce the notion of intuitionistic interval-valued fuzzy sets as the another generalization of interval-valued fuzzy sets and intuitionistic fuzzy sets and hence fuzzy sets. Also we introduce some operations over intuitionistic interval-valued fuzzy sets.
