Extensions of Rough Set Model and Set Pair Analysis in Incomplete Ordered Decision System
不完备序值决策系统中的拓展粗集模型及集对分析

In incomplete ordered decision system,the tolerance dominance relation is too loose while the similarity dominance relation is too strict for classification analysis.By these explanations,this paper proposed the rough set models based on limited tolerance dominance relation.Moreover,we introduced the set pair analysis into incomplete ordered decision system,the rough set models based on connection degree were also presented.An illustrative example was used to show the validity of proposed dominance relation...
