为了消除不同评价指标中不同的量纲和量纲单位带来的不可公度性,本文讨论了综合评价中数据变换方法的选择问题.根据序号总和理论,本文将各评价指标作无量纲化处理,根据各无量纲化方法所做的等级排序与合理等级排序的"距离"进行无量纲化方法的优选,并通过实例分析得出了相应的结论.均值化方法保留了各指标变异程度的信息,是一种较好的数据处理方法.
為瞭消除不同評價指標中不同的量綱和量綱單位帶來的不可公度性,本文討論瞭綜閤評價中數據變換方法的選擇問題.根據序號總和理論,本文將各評價指標作無量綱化處理,根據各無量綱化方法所做的等級排序與閤理等級排序的"距離"進行無量綱化方法的優選,併通過實例分析得齣瞭相應的結論.均值化方法保留瞭各指標變異程度的信息,是一種較好的數據處理方法.

The different evaluating indicator often has the different dimension and the Dimensional unit,to eliminate the commensurability coming from this, we should also. do zero dimension processing to each evaluating indicator. The rationality of an undimensionalized method depends on the rationality of the rank it assigns to objects. Under the premise of establishing gist of rational rank, we can choose the best one from non-dimensionalized methods according to the distance between the ranks assigned by them and the rational rank collocation, and draw relavent conclusions through practical analysis.
