直觉模糊S-粗决策模型及应用

Intuitionistic Fuzzy S-rough Decision Models and Application

基于直觉模糊S-粗集理论,提出双向直觉模糊S-粗决策模型。首先给出指标值的量化方法,将目标矩阵进行标准化处理。其次,建立直觉模糊S-粗决策的上-决策和下-决策优化模型,并给出直觉模糊S-粗决策算法及详细步骤。最后,以空袭目标为例,详细研究了目标威胁程度评估过程。结果表明,直觉模糊S-粗决策模型能够综合处理决策因素的定性与定量因素,得到的决策结果综合性能最优。所得的排序结果真实、准确地反映了实际情况。

Based on the theory of intuitionistic fuzzy S-rough sets, the two direction intuitionistic fuzzy S-rough decision model was proposed. First, approaches to measures for evaluating goals and normalization of goals matrix values were described. Then, the models of above-decision and under-decision of intuitionistic fuzzy S-rough decision were founded; the arithmetic and detailed processes of intuitionistic fuzzy S-rough decision were given. Finally, the threat evaluating instances were detailed in the course of air attack goals. The results show that the intuitionistic fuzzy S-rough model can treat decision ingredients with all-around and the result reflects the truth well and truly.
