摘　　要：根据样本单元和待评价决策单元的区间投入、区间产出定义最大广义生产可能集,建立基于最大广义生产可能集的广义区间DEA模型,然后定义了待评价决策单元基于广义区间DEA模型的区间效率,并对待评价决策单元进行了有效性分类,最后通过实例表明了广义区间DEA模型的实用性.Based on interval inputs and outputs of the sample unit and dectston making umt, t.e maximum generalized production possibility set is defined to establish the generalized interval data envelopment analysis （DEA）. And then based on the generalized interval DEA the interval efficiency of the decision making unit is defined to classify the the decision making unit. Finally,an example is offered to demonstrate the practicality of generalized interval DEA.
