The purpose of this paper is to introduce fuzzy set theory which has a number of properties that makes it suitable for formalizing the uncertain information in dealing with systems comprising a very large number of interacting elements or involving aLarge number of variables in their decision trees.

Basically Fuzzy set theory is affecting every aspect of life; social life is one of them. Fuzzy set theory has proved as mile stone in its development. Selection of one of the solutions for social life’s problems and selection of possible way for the development of social life is become possible only due to ranking of fuzzy set theory.
