【摘要】 提出了一种消除评价指标相关性的方法 .该方法在评价指标相关矩阵的基础上 ,首先对指标集合进行等价类划分 ;然后利用随机向量线性相关性 ,对指标等价类加以优化求解 ,使得指标等价类之间的相关性最小 ,进而得到等价类的指标综合函数 .最后根据等价类的指标综合函数进行系统评价 .文中还给出了一个实际案例 ,说明了本文方法的应用更多还原

【Abstract】 In this paper, an approach of eliminating correlation of assessment\|index is proposed. Based on correlation matrix, assessment\|indices are partitioned into several equivalence classes. This approach minimizes the correlation among the equivalence classes by use of linear correlation of random vectors and optimization methods such that the synthetic function can be obtained. An example is also given to illustrate the proposed method.更多还原
