摘要
利用粗糙集中属性约简的思想来确定各属性的重要程度,对属性依赖度进行计算,构造出属性间相对依赖的客观判断矩阵。在此基础上将客观矩阵和利用层次分析法确定的主观矩阵相结合,提出了一种组合矩阵,通过计算组合矩阵的权重来进行决策。实例表明该方法是切实可行、有效的,能提高决策精度。
By the idea of attributes reduction in rough set theory,the significance of attributes is determined,and dependability of conditional attribute is calculated to construct comparison matrix of relative dependability of attributes.Then the combinatorial matrix is proposed based on objective matrix and subjective matrix determined by analytic hierarchy process,which weight needs to be calculated for decision.Finally,specific data prove the feasibility,effectiveness and higher design accuracy of the method.
