(Caution: sometimes ⊂ is used the way we are using ⊆.) In fuzzy logic, three operations, including fuzzy complement, fuzzy intersection and fuzzy union, are the most commonly used. Subsets A set A is a subset of a set B iff every element of A is also an element of B.Such a relation between sets is denoted by A ⊆ B.If A ⊆ B and A ≠ B we call A a proper subset of B and write A ⊂ B. Set Difference . Example: Consider the family F of half-open intervals of real numbers, [0,r). Let fuzzy sets A and B be described by their membership functions μ A (x) and μ B (x).The three fuzzy set operations are defined below.
