摘要
针对不完备偏好决策问题,提出一种基于拓展粗糙集的决策分析模型。首先提出限制容差优势关系的定义;然后得到限制容差优势关系下的粗糙近似和分类决策规则。最后通过一个实例证明了所提出的模型对不完备偏好信息系统的处理符合实际情况。
A decision analysis model based on extension of rough set is proposed for multi-attribute decision making problems with incomplete preference information.Firstly,the concept of limited tolerance dominance relation is presented.then,the rough approximations of knowledge are obtained based on limited tolerance dominance relation and the decision rules of classification are acquired.Finally,an example shows the feasibility and effectiveness of the model.
