摘　　要：利用DEA解决资源分配问题时,集中决策单元下属的子决策单元间必须具备同质性,但在许多情况下,子决策单元不满足这个条件。为解决此类问题,提出非同质决策单元间的资源分配模型。模型首先引入多个集中决策单元,并根据子决策单元的非同质性进行分类;为每一类子决策单元分别刻画其生产可能集和改变可能集,在此基础上,考虑资源约束,寻找最佳资源分配方案。最后,通过数值算例说明模型的管理意义。All subunits belonging to a same centralized decision making unit （DMU） must be homogeneous when one solves resources allocation problem for centralized DMU by the method of data envelopment analysis （DEA）. If subunits are heterogeneous, traditional DEA method can not be valid. In this paper, we establish a new model to deal with such a situation. Multiple central DMUs are introduced and all subunits are classified according to their heterogeneity for all centralized DMUs. Production possibility set and transformation possibility set are defined for each kind of subunit. Based on both sets, our model can find the best resource allocation solution under resource constraint. Numerical examples are used to illustrate the approach and its implication for management science.
