A Combined Use of Soft Sets and Grey Numbers in Decision Making

Abstract

Decision making is the process of evaluating multiple alternatives to choose the one satisfying in the best way the required goals. The classical methods for decision making cannot always be applied due to the various forms of existing uncertainty in the corresponding problems. As a result, various methods for decision making under fuzzy conditions have been proposed. In this work, a new parametric decision-making method is introduced using a combination of soft sets and grey numbers as tools, which modifies a method with soft sets proposed by Maji, Roy, and Biswas. The importance of this modification is illustrated by an application concerning the decision for the purchase of a car satisfying in the best possible way the goals put by the candidate buyer.
