摘要
在已有DEA模型基础上,建立起非径向、同时考虑输入与输出的区间DEA模型,以测度决策单元的区间技术效率。基于相对合理的区间效率测度,对决策单元进行了分类,并给出了非区间有效单元的一个改进方案。最后给出了一个算例。
A non-radial interval DEA model is presented to measure efficiency score of DMU,in which simultaneous input/output orientation is considered.DMUs are classified based on their relatively reasonable interval efficiency scores,a scheme of improving inefficient DMUs is presented based on measurement of interval efficiency score.In the end,an empirical example is illustrated.
