摘　　要：用概率信息系统表示对象与属性值之间的概率关系.根据粗糙集理论,采用平均算子,获取概率信息系统的扩展决策规则集.用关系合成的模糊推理方法,实现了扩展决策规则集的决策推理.A probabilistic information system was used to express the uncertainty relationship between objects and attributes. Based on rough sets and average operator, extended decision rules of the probabilistic information system were obtained. Decision inference of the extended decision rules was implemented using fuzzy CRI （compositional rule of inference）.
