优势关系下的区间值信息系统及其属性约简
Interval-valued information system based on dominance relation and its attribute reduction
摘要
Abstract
Aiming at interval-valued information system, a new dominance relation is presented, then upper and low approximation sets of this system are constructed which are based on this dominance relation.Attribute reduction of interval-valued information system is displayed with discernibility matrix.An example illustrates that this method is simple and easy.关键词
