The intersection form of production possibility set in DEA and its applications

Abstract

DEA理论、模型及方法可用以评价给定决策单元之间的相对有效性,其在经济学中的应用体现在经验生产可能集的构造上.DEA的生产可能集有两种等价形式—和形式及交形式.相比较而言,交形式更具几何直观性及计算便利性. The DEA theory,model and method are used to evaluate the relative efficiency among the given decision making units,the applications in the economics are reflected in the construction of production possibility set.Production possibility set in DEA has two equivalent forms: sum form and intersection form.In comparison,the later one has more geometric visualization and convenience of calculation.
