Abstract

Zadeh introduced the theory of fuzzy sets as a generalization of ordinary (exact) sets. These sets are used to model ambiguous concepts that abound in real-world problems. This theory paved the way for other theories to claim more or less the same. Each of these theories can be considered a generalization of fuzzy set theory. Some of the most important include value interval sets, intuitive fuzzy sets, type ف fuzzy sets, multiple fuzzy sets, hesitant fuzzy sets, and neutrosophic sets.
