摘　　要：给出基于输出的DEA模型下的区间有效值求法,同时从乐观和悲观两个角度去评价决策单元,从而得到了该决策单元有效值的一个区间.进一步还可类似地定义该决策单元无效的一个区间.将上述方法与基于输入的DEA模型下的理论进行了对比,实例分析显示了两种模型在评价决策单元区间有效性上是一致的.A new DEA with an interval efficiency under output-DEA model is developed. An original DEA model is used to evaluate each DMU optimistically. A DEA model is formulated with an interval efficiency which consists of efficiencies obtained from the optimistic and pessimistic viewpoints. Thus, two end points can construct an interval efficiency. The interval inefficiency model, which is inverse to interval efficiency, can also be dealt with by the same idea. Finally, the two results under input DEA model and output DEA model are compared with each other respectively through an example, which confirm the consistency of the interval effectivities of decision-making units evaluated by these two models.
