摘要:

针对含有不完全偏好信息的多属性决策问题,提出了基于先验概率优势关系的粗糙决策分析模型。首先分析了扩展优势关系和限制扩展优势关系的不足,在此基础上提出先验概率优势关系的概念,并得到先验概率优势关系下的粗糙近似;然后通过对比分析,证明了新模型较上述两种优势关系模型可使分类结果更加符合实际情况和人在数据处理过程中的直观感受。最后,通过一个实例验证了新方法的可行性和有效性。

Abstract:

A decision analysis model based on prior probability dominance relation is proposed to solve multi-attribute decision making problems with preferential and incomplete information. Firstly,in order to avoid the limitations of the extended dominance relation and limited extended dominance relation,the concept of prior probability dominance relation is presented and the rough approximations of knowledge are obtained based on the limitations.Then,compared with the extended dominance relation and limited extended dominance relation,the classification based on the prior probability dominance decision analysis model is more realistic and fits intuitive feeling better. Finally,the example shows the feasibility and effectiveness of the proposed method.

Key words: multi-attribute decision, rough sets, extended dominance relation, limited extended dominance relation, prior probability dominance relation
