全序优势关系下区间信息系统多粒度粗糙集的粒度约简

On Particle Size Reduction of Multi-granularity Rough set in Interval Information System with Total Order Dominance Relation

多粒度粗糙集是近年来粗糙集理论中兴起的一个研究方向。该文针对优势关系下的区间信息系统的多粒度粗糙集,提出了相对粒度约简的概念,给出了基于粒度重要性的粒度约简算法。用实例来进行具体分析该方法的有效性。

Multi-granularity rough set is a rise as a research direction in rough set theory in recent years. According to information system based on dominance relation, the interval of the granularity of rough sets, the paper puts forward the concept of relative particle size reduction, size reduction algo- rithm based on granularity importance, and use instance for the specific analysis of the effectiveness of the proposed method.
