| 摘 要： | 当决策单元的变量取值区间范围较大时,经典区间DEA求解算法求得的相对效率区间长度也可能较大,对决策单元有效性的解释力低,很难直观反映相对效率的大小。将决策单元的变量区间划分为若干个子区间,分别计算决策单元在各子区间上的DEA效率,进而求得综合效率区间,作为评价决策单元有效性的基准。综合效率区间的区间长度比经典算法的求解结果小,将新算法应用于投资项目的效率评价,便于对投资项目的效率大小进行比较,进而为项目投资决策提供科学依据。

| Abstract: | Efficiency interval length might be too long to evaluate the effectiveness of decision-making units well if range of input and output variables interval is large. Divides input and output interval into sub-intervals,and calculates efficiency of decision-making units in different sub-intervals respectively,furthermore,comprehensive efficiency intervals are solved to use as standards of effectiveness evaluation. Length of comprehensive efficiency intervals is shorter than that in the results of classical algorithms,which is easy to be used to compare efficiency of investment projects as applying to evaluate the investment projects. |
