Abstract: By introducing level soft sets into fuzzy soft sets, the soft discernibility matrix can be used to deal with decision making problems. First, by using level soft sets in fuzzy soft sets, the fuzzy soft sets can be transformed into crisp soft sets. Then, the concept of soft discernibility matrix is used in soft sets. An algorithm based on soft discernibility matrix is proposed to solve the problems of decision making. Finally, an example is given to show the feasibility of the method.

摘要： 通过在模糊软集中引入水平软集，用软区分矩阵来处理决策问题。首先，利用模糊软集的水平软集，将模糊软集转化为经典软集。其次，在软集中引入软区分矩阵的概念，提出了一种基于软区分矩阵解决模糊软集的新算法来处理决策问题。最后，通过实例说明了该算法的可行性。
