| 摘 要： | 在直觉模糊信息系统的背景下提出了基于容差关系的直觉模糊粗糙集模型，从乐观悲观两个角度出发对目标集进行刻画，是对目标集的一种新的逼近方法，同时，可以发现乐观与悲观上下近似的关系.通过求解近似精度可以发现乐观直觉模糊粗糙集模型的近似精度更高.最后给出实证分析，进一步验证结论的有效性.

| Abstract: | This paper proposes the intuitionistic fuzzy rough set models based on tolerance relation in intuitionistic fuzzy information system,in which the target concept is described from two aspects of optimistic and pessimistic,which is a new approximation method for target concept.In addition,some relationship is found between optimistic and pessimistic approximations.The approximate accuracy of optimistic intuitionistic fuzzy tolerance rough set is higher than that that of the pessimistic one according to the definition of approximation accuracy.Finally,the empirical analysis is provided,which verifies the effectiveness of the presented method. |
