Intuitionistic Fuzzy S-rough Decision Models and Application
直觉模糊S-粗决策模型及应用

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 abovcdecision and under-decision of intuitionistic fuzzy trough 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 trough model can treat decision ingredients with all-around and the result reflects the truth well and truly.
