摘要
针对交叉效率模型中各决策单元的标准的权重问题,提出利用离差最大化的方法来确定各决策单元的标准的权重。首先利用交叉效率模型计算得到评价问题的交叉效率矩阵,然后利用离差最大化的方法计算交叉效率矩阵中各评价单元的标准的权重。最后利用加权求和法计算各决策单元的最终效率得分并进行排序。通过算例分析说明了方法的有效性。
Considering the problem how to determine the weight of each decision unit in the cross efficiency mod- el, a method of maximizing deviations is introduced to solve this problem. First we calculate the cross efficiency matrix using the cross efficiency model, and then use the maximizing deviations method to determine the weight of every decision unit. Finally, the weighted summation method can be used to determine the final efficiency of all the decision units by which the decision units can be ranked. And an example is given to illustrate the effectiveness of the method vronosed.
