摘　　要：利用单向S-粗集,给出单向S-粗决策规律生成方法;给出上决策规律,下决策规律,单向S-粗决策规律核,单向S-粗决策规律带,单向S-粗决策规律壳的概念;利用这些概念,提出下决策规律传递定理,上决策规律传递定理,F-分离的属性定理,粗决策规律挖掘定理,与粗决策规律挖掘准则。One direction S-rough sets have one direction dynamic characteristics. By using one direction S- rough sets, a method of one direction S-rough decision law generation is presented and the concepts of upper decision law, lower decision law, one direction S-rough decision law kernel, one direction S-rough decision law band and one direction S rough decision law hull are proposed. And then by using these concepts, the theorem of lower decision law transfer, the theorem of upper decision law transfer, the theorem of F seperation attrib ute, the theorem of rough decision law mining and the rough decision lawraining criteria are presented.

关 键 词：单向S-粗集 单向S-粗决策 规律挖掘准则 粗决策规律
