Multi parameter fuzzy soft set approach to decision making problem

In this paper, a new approach for decision making problem is introduced by extending the definition of fuzzy soft set for multiple parameter sets and is called extended fuzzy soft set. Also, few operations such as “AND” and “ ” are defined on extended fuzzy soft sets and illustrated with examples. Further an algorithm for decision making using the concept of extended fuzzy soft set is presented. The decision making process includes construction of comparison matrix and ranking strategy is based on the row sum of comparison matrix. Finally an application of proposed algorithm for decision making is presented. Key words: Fuzzy soft set, decision making, comparison matrix, ranking.
