Abstract
In 1965, Lotfi A. Zadeh (Fuzzy sets. Inf. Control 8, 338–353, 1965) [34] introduced a new type of set called a fuzzy set and a new logic later known as fuzzy logic. Instead of YES or NO, regarding the existence of an element in a set, he used the degree of membership, which allows an element to exist in a set with a partial grade of membership. The applications of fuzzy logic are profound and widespread.
