A Study on Selected Mathematical Theories for Decision-Making Problems
Main Article Content
Abstract
The most appropriate mathematical theory for dealing with uncertainty in decision making problems, the theory of fuzzy set developed by Zedeh in 1965. Later in 1999, Molodstov introduced another one namely, soft set theory for modelling vagueness and uncertainty in decision making problems. In this paper, we study some mathematical tools such as fuzzy set, soft set and fuzzy soft set for solving decision making problems.
