摘要
针对传统数据包络分析方法无法依据确定参考面提供评价信息的弱点,给出了带有偏好锥的样本数据包络分析模型(PSam-C2WH)和相应的SCDEA有效性及弱有效性概念。分析了(PSam-C2WH)模型的性质以及它与传统DEA模型之间的关系,探讨了(PSam-C2WH)模型刻画的SCDEA有效性及弱有效性与相应的多目标规划非支配解之间的关系。进而,分析了决策单元在样本可能集中的分布特征、投影性质和模型含义等问题。
To solve the problem that data envelopment analysis （DEA） methods can not provide evaluating information by a determinate frontier, a new sample DEA method with restrain cone （PSam-C^2 WH） is provided by using some sample units. At the same time, the definitions of SCDEA-efficlency and weak-SCDEA-efficiency are developed. The relationships between （PSam-C^2WH） and other evaluation models are discussed. In addition, the relationship between SCDEA-efficiency and the relevant multiple objective programming pareto effective solution is studied. Finally, the properties on projection and distribution of decision making units are studied, and the meaning of SCDEA-efficiency and weak-SCDEA-efficiency are explained.
