摘　　要：为了用集对分析方法进一步刻画不完备信息系统,文中把新集对分析理论与粗糙集理论结合在一起,提出了一种新的集对粗糙集模型,从而拓宽了集对分析方法的应用;定义了一种不完备信息系统的上、下近似算子,得到了一些相关的性质。最后通过一个简单的例子说明了上述方法的可行性。In order to describe the incomplete information system, the rough set model based on a new idea of set pair analysis is proposed by introducing a new idea of set pair theory into rough sets in this paper, which extends the application of set pair analysis. The upper approximation and the lower approximation operators are defined in incomplete information system. Furthermore, some related properties are discussed. Finally, by an example, it is verified that this method is more feasible.

关 键 词：不完备信息系统 集对分析 粗糙集
