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。
The set-valued information system was analyzed by dominance-based 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 dominance-based rough set theory.The fuzzy dominance-based 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.
