Windows Multiplicative CCR-O DEA Model

Some ways of comparison from results of Windows Multiplicative DEA model versus traditional Windows DEA model (raw/standard). Now, it is also including the LINDO´s formulations of the multiplicative windows DEA model bringing a sum of the slacks with a small infinitesimal number (ε=10^(-7)) in the objective function; however, the results are equals than the original windows multiplicative DEA formulation which has no slacks in the objective function, only in inputs and outputs formulations respectively.

本数据集收录了用于对比窗口型乘法数据包络分析（Windows Multiplicative Data Envelopment Analysis, DEA）模型与传统窗口型数据包络分析（Windows DEA）模型（含原始、标准化两个版本）结果的若干方法。此外，本次数据集还纳入了基于LINDO软件构建的窗口型乘法DEA模型的模型设定：该设定在目标函数中引入带有极小无穷小量（ε=10^(-7)）的松弛变量求和项，但所得结果与原始窗口型乘法DEA模型设定完全一致——后者仅在投入与产出的约束式中分别设置松弛变量，目标函数中不含松弛变量。
