摘　　要：针对S-粗集模型及其现有扩展模型不能有效处理具有动态特性的偏好信息系统这一缺陷,本文提出了一种双向S-变精度优粗集模型,并给出了该模型的一些性质。新模型具有一定的抗数据干扰能力,从而可在动态偏好信息决策系统中获得更加合理的分类;最后给出一个应用实例,验证了新模型的有效性。Aiming at the defect that the S-rough set model and its existing extension model cannot effectively deal with a preference decision-making system with dynamic characteristics, in this paper, two direction S-variable precision dominance-based rough set model is proposed and some properties of the model are given. The new model has a certain ability to resist data interference, which can obtain more reasonable classification in the dynamic preference decision-making system. At last, an application example is given to verify the validity of the new model.
