FUZZY SETS AND ITS APPLICATION IN DECISION MAKING PROBLEMS BY COMPARING THREE METHODS

Abstract

Fuzzy sets are beneficial tool to detailed concept of uncertainty in decision making process. Making decisions is one of the most important activities of human beings. The field of decision making are the most effective and interesting area of application of fuzzy set theory. In this paper, we consider the theory of fuzzy sets to solve a real-world decision-making problem. The selection of the best one by defining linguistic value, Normalization and Weighted Normalized Decision matrix by using a Weighted sum method, Weighted Product method and Analytic Hierarchy Process. Comparing all and get a best one.
