(a) Define $\alpha$-cut and strong $\alpha$-cut for a fuzzy set. Given fuzzy set $A=\{1 / x 1+0.8 / x 2+0.3 / x 3+0.2 / x 4\}$. Find $A \alpha=0.3$.

Explanation

The $\alpha$-cut of a fuzzy set A is an important concept in fuzzy set theory. It is used to extract the elements of A that have a membership value greater than or equal to $\alpha$. The strong $\alpha$-cut of A is the set of all elements x in A such that the membership value of x in A is equal to 1.
