摘要:

基于软区分矩阵,首先提出了不完备软区分矩阵的概念,讨论了不完备软区分矩阵的相关性质;接着提出了基于不完备软区分矩阵的决策算法。该算法可以通过扫描一次不完备软区分矩阵就能得到所有对象的序关系,从而可得最优选择对象和次优对象。最后,通过实例来说明该方法在决策问题中的正确性和有效性。

Abstract:

Based on soft discernibility matrix,we first present the concept of incomplete soft discernibility matrix in soft sets and analyze its related properties.Then,we propose a novel decision making algorithm based on incomplete soft discernibility matrix.It can get an order relation of all the objects easily by scanning the incomplete soft discernibility matrix at one single time,thus finding the optimal choice object and the suboptimal object.Finally, the correctness and effectiveness of the algorithm in decision making are proved by examples.
