摘要
将区间DEA模型扩展到变量为三参数区间灰数的情形。研究了变量为三参数区间灰数时,决策单元(DMUs)的DEA效率区间的一般性求解算法。提出了决策单元取数一致准则,在决策单元取数一致准则下对DEA效率区间的一般性求解方法进行了修正,得到了灰度更小的计算结果,并用算例进行了验证。
This paper measures DEA efficiencies of decision making units (DMUs) with three parameters inter- val grey data. Furthermore, the improved method of efficiencies measuring is proposed on the basis of "Equity prin- ciple of DMUs", which assumes all grey interval inputs and outputs of DMUs on the same index as data being unan- imous. The grey degrees of DEA interval efficiencies solved from the new method are smaller, tested by a numerical example.
