优势关系决策信息系统的属性约简

摘要

In order to effectively deal with inconsistent data,we have studied an approach to attribute reductior in general decision systems based on dominance-based rough sets,and presented some important properties of attribute reductions.Finally,an example is employed to show that the proposed reduction method is an effective technique.%为有效处理不一致决策的数据,通过定义决策正域的概念,提出了基于优势关系的一般决策信息系统的属性约简方法,并对约简性质进行了分析.最后通过实例说明了属性约简方法的有效性.
