| 摘 要： | 逆DEA模型讨论了在保持决策单元的效率指数(即最优值)不变的情况下,当输入水平给定时估计输出值.在逆DEA模型的基础上研究了效率指数提高的输出估计,讨论了带有随机因素的情况,将该问题转化成机会约束的线性规划问题,并用数值算例加以说明.

| Abstract: | In this paper we show that the inverse data envelopment analysis(DEA) models can be used to estimate outputs for a decision making unit(DMU) when some or all inputs and efficiency level of this DMU are increased or preserved.The problem with stochastic factors is transformed to a chance constraint programming.Finally,a numerical example is shown as an illustration. |
