中文摘要：

针对序信息系统下经典优势关系过于严格的不足,首先提出了概率优势关系的粗糙集模型,并分析了相关性质。然后提出了基于此模型的排序方法,这可以避免主观权重的确定。并将此排序方法用于物流供应链的绩效评价中,通过与其他方法排序结果的对比,显示该方法得出的结果更加合理。

英文摘要：

Aiming at the deficiency of strict classic dominance relation under the ordered information systems,the probabilistic dominance relation rough set model is firstly proposed and the relevant properties are analyzed.Then a project sorting method based on the model is proposed,which can avoid the subjective weight determined.The proposed sorting method is used to evaluate the performance of the logistics supply chain.The expoviment results show that the method proposed in this paper is more reasonable.
