一种锥比率数据包络分析模型及有关结论

本文研究一种锥比率数据包络分析模型,它既能反映各项输入或输出的相对重要性和对某些决策单元的偏好,又可单纯地评价决策单元间的相对技术有效性。本文着重讨论这一模型的DEA有效性与多目标规划非支配解的关系以及有效决策单元的存在性等问题,论证了有关结论。

A Cone Ratio Data Envelopment Analysis Model and Related Conclusions

This paper studies a cone ratio data envelopment analysis model that not only can reflect the relative importance of various inputs (outputs) and the preference for some decision making units but also can purely evaluate the relative technical efficiency of decision making units. This paper put emphasis on discussing the relation between DEA efficiency corresponding to this model and nondominated solution of multiobjective programming and discussing the existence of effective decision making units. The conclusions concerned have been proved.
