基于有限扩展优势关系的粗糙决策分析方法

针对基于扩展优势关系的粗糙决策分析方法的局限性，本文给出了一种新的基于拓展粗糙集的多属性决策分析方法。首先提出了有限扩展优势关系的概念；其次在有限扩展优势关系下得到知识的粗糙近似，给出了分类决策规则；第三，通过对比分析，证明了新方法的性能优于现有方法；最后通过一个实例验证新方法的可行性和有效性。

An Analysis Method of Rough Multi-attribute Decision Making Based on Limited Extended Dominance Relation

Since analysis method of rough decision making based on extended dominance relation has its limitations, a new decision analysis method based on extension of the rough sets is proposed to multi-attribute decision making problems with preferential and incomplete information in this paper. Firstly, the concept of limited extended dominance relation is presented, secondly, the rough approximations of knowledge are obtained by limited extended dominance relation and decision rules of classification are acquired, thirdly, new method proves to be better than old one by contrast analysis, finally, the feasibility and effectiveness of new method are demonstrated by a real example.
