| 摘 要： | 针对当前区间序信息系统上五种优势关系的不足，提出了一种新的优势关系-α-可能度优势关系。分析了α-可能度优势关系的基本性质以及与其他优势关系的联系，进而定义了基于α-可能度优势关系的扩展粗糙集模型。算例表明，α-可能度优势关系通过α的变化来调节优势关系的“优于”程度，能够克服以往优势关系定义过宽或过窄而带来的不足。 |

| Abstract: | To sovle the deficiencies of five dominance relations in interval ordered systems,a new dominance relation-α-possible degree dominance relation is proposed.The basic properties of α-possible degree dominance relation and the relationships with other dominance relation are analysed.Furthermore,an extended rough set based on α-possible degree dominance relation is defined.The example shows that:by the variety the value ofα to adjust the degree of dominance,α-possible degree dominance relation can overcome the deficiencies of former dominance relation in in interval ordered systems. |
| Keywords: | interval ordered information system α-possible degree dominance relation rough |
