摘要
优势粗糙集方法是研究不完备区间值信息系统的一种重要方法。针对当前不完备区间值信息系统研究中存在的问题,提出了两种新的优势关系,即上限优势关系和近似优势关系。在此基础上,研究了对象评估和不确定性度量问题,给出了不同优势关系间的区别与联系,最后利用具体算例加以说明。
Dominance-based rough set approach is an important method to study incomplete interval-valued information systems. To solve outstanding problems in incomplete interval-valued information systems, we proposed two new domi- nant relations--the upper-limit dominance relation and the similarity dominance relation. Based on these two relations, we studied object ranking and uncertainty measurement, and showed the difference and relationship between the two proposed dominance relations. Examples were provided to substantiate the proposed concept.
