摘要
本文从工程多指标评估实用出发,根据灰色统计矩阵确定表示评估指标重要程度的灰色权系数。用灰色权系数代替文献[1]灰色聚类方法中的折算系数,从而提出了考虑各指标重要性的灰色统计—类方法。用该方法对15个矿务局的效益进行了综合评估,完全符合实际情况。
From engineering practice of multi-index estimation, this paper determines grey weight coefficient of estimation index according to grey statistical matrix. When the grey weight coefficient substitute for the estimation coefficient in [l],a grey statistical aggregation method with various index importance has been given. Using this method, according to the estimation of efficiency of fifteen mines, the result agreed with real conditions.
