Revisiting fuzzy set operations: A rational approach for designing set operators for type-2 fuzzy sets and type-2 like fuzzy sets

Expert Systems with Applications, 2018
Abstract Created by Zadeh in 1965, Fuzzy Set Theory (FST) has been continuously developed in the past five decades and has established itself one of the preeminent approximate reasoning methodologies. In the literature, there exists multitudes of differing approaches for specifying FST's foundational building blocks (such as the various versions of ...

Properties of type-2 fuzzy sets

2017 International Conference on Fuzzy Theory and Its Applications (iFUZZY), 2017
In the paper, new definition of type-2 fuzzy sets (T2 FSs) are introduced, and then some basic concepts such as unit fuzzy set, embedded unit fuzzy sets, closure of support (CoS), restriction of type-2 fuzzy set at a point, etc. and partition of CoS is given to represent general type-2 fuzzy sets, finally, the connections among the restriction of T2 ...

Non-stationary type-2 fuzzy sets

Proceedings of the 10th World Congress on Intelligent Control and Automation, 2012
In this paper, we introduce non-stationary type-2 fuzzy set (NST2FS), which is the important extension of its type-1 counterpart. NST2FS has distinct characteristics with uncertain membership function and alteration over time. According to different mathematical formalizations of its instantaneous T2FS (IT2FS), NST2FS can be divided into two categories,

Three-way decisions based on type-2 fuzzy sets and interval-valued type-2 fuzzy sets

Journal of Intelligent & Fuzzy Systems, 2016
This paper investigates three-way decisions of type-2 fuzzy sets and interval-valued type-2 fuzzy sets based on partially ordered sets. First, the partially ordered sets, constituted by fuzzy truth values and interval-valued fuzzy truth values, are established, respectively. They serve as the basic structures of three-way decision spaces.

Working with Type-2 Fuzzy Sets

2017
This chapter explains how to work with type-2 fuzzy sets (T2 FSs). Most of its topics are needed in the rest of this book. Coverage includes: set-theoretic operations (union, intersection, and complement) for general type-2 fuzzy sets (GT2 FSs) computed using the Extension Principle, set-theoretic operations for interval type-2 fuzzy sets (IT2 FSs ...

Interval Type-2 Fuzzy Rough Sets and Interval Type-2 Fuzzy Closure Spaces

2015
The purpose of the present work is to establish a one-to-one cor- respondence between the family of interval type-2 fuzzy reexive/toleranc e approximation spaces and the family of interval type-2 fuzzy closure spaces.

Type-2 Fuzzy Sets and Beyond

2013
This chapter explains why I started working on type-2 fuzzy sets and systems and the contributions made by my students, colleagues and myself to this field. It also predicts a very rosy outlook for this field.
