摘　　要：针对基于优势关系的协调序决策系统,定义了条件属性集相对于决策属性集的贴近度,并定义了协调序决策系统中属性的重要度.提出了基于贴近度的启发式属性约简算法,通过实例分析证实了该算法的有效性.The close-degree was introduced into the consistent ordered decision system which was based on the dominance relation. The close-degree of condition attributes relative to decision attributes in the consistent ordered decision system was defined. The significance of attribute was also defined,and a heu-ristic attribute reduction algorithm based on the close-degree was proposed. The validity of the algorithm was tested by an example,and the results showed that the algorithm was efficient for the attribute reduc-tion of consistent ordered decision system.
