| 摘 要： | 建立输入输出要素部分可控和部分不可控的情况下的多目标DEA(data envelopment analysis)模型,通过其对偶模型和标量化,给出多目标DEA有效的概念并研究其性质。给出各种Pareto有效解的定义并建立其与多目标DEA有效的等价关系,通过将决策单元投影到生产前沿面上得到新的多目标DEA有效的决策单元,由此说明权重的作用。

| Abstract: | A multiobjective DEA model and its dual through weighting coefficients are put forward for the system with partial controllable and partial uncontrollable input and output factors.The multobjective DEA efficiency for a decision making unit is defined and investigated.Some Pareto efficient solutions are also suggested and their equivalent relationships with multobjective DEA efficiency are established.A new multobjective DEA efficient unit,which is called a projection,can be got by projecting the unit onto the production foreland.The projection can be adjusted by changing the weighting coefficients. |
