(EIA) and Hao–Mendel Approach (HMA)] for estimating (synthesizing) an interval type-2 …

Lotfi Zadeh, the father of fuzzy sets and fuzzy logic, introduced many of their important
concepts, two of which are discussed in this article namely, type-2 fuzzy sets and computing …

This paper focuses on an approach, called the HM Approach (HMA), to determine (for the
first time) a normal interval type-2 fuzzy set model for a word that uses interval data about a …

Similarity measures are among the most common methods of comparing type-2 fuzzy sets

In this paper, we extend the concept of Dempster-Shafer Belief Structures to the case of
Linguistic Belief Structures, whose focal elements and probability mass assignments are …

This article provides a high-level retrospective of type-2 fuzzy sets and fuzzy logic systems. It
explains how type-2 fuzzy sets can be used to model membership function uncertainties …

For over four decades decision support systems have been emerging to facilitate decision
making under uncertain conditions and in a rapidly changing unstructured environment …

Classical automata, fuzzy automata, and rough automata with input alphabets as numbers
or symbols are formal computing models with values. Fuzzy automata and rough automata …

Present-day handheld battery-enabled devices such as smartphones and tablets attract rich
