| 摘 要： | 以集值信息系统为研究对象，考虑对象之间的优势程度，提出了模糊优势关系的概念;将模糊的方法引入优势关系粗糙集理论，给出了基于模糊优势关系的粗糙集模型并讨论了其相关性质，为从集值决策系统中获取决策规则提供了新的理论基础与操作手段。通过实例验证了所提方法的可行性和有效性。

| Abstract: | The set valued information system was analyzed by dominanccbased rough set approach. By considering the dominance degree in terms of pair of objects, the concept of fuzzy dominance relation was proposed, the fuzzy technique was then employed in the dominanccbased rough set theory. hhe fuzzy dominanccbased rough set model was presented, then corresponding properties were discussed, from which we obtained new theory and practical approach to derive decision rules from the set valued decision system. Some numerical examples were employed to substantiate the conceptual arguments. |
