对决策信息系统的属性约简算法和决策规则约简算法进行了研究,在所研究的属性约简算法基础上提出了基于核值的决策规则约简算法及对决策规则的优劣排序算法,有利于提高决策分析的效力。
The algorithm of attribute reduction and decision rule reduction of decision information system is studied. Based on the attribute reduction algorithm, a reduction algorithm of decision rules based on kernel value and the algorithm of ranking rules and bad points are proposed. Help to improve the effectiveness of decision analysis.
