基于样本的企业联盟效率综合评价的非参数方法

Non-parametric approach for evaluating alliance efficiency based on sample units

从系统组成成员的资源共享出发,针对传统样本数据包络分析方法无法突破决策单元具有"可比性"的限制和无法依据任意参考面提供评价信息的弱点,给出了带有约束锥的评价企业联盟效率的广义样本数据包络分析模型(PU-C^2WH),分析了该模型刻画的联盟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,探讨了联盟单元在样本可能集中的投影性质和无效单元效率改进的途径和尺度,并进一步给出了联盟单元群整体效率度量的典型方法和评价步骤,最后,将该方法进行了仿真应用.

Based on resource sharing, to solve the problem that sample data envelopment analysis methods can not provide evaluating information by a determinate frontier and can not breakthrough the comparability restriction of decision-making units, a broad sample DEA method with restrain cone （PU-C2WH） for evaluating alliance efficiency is provided by using some sample units. At the same time, the definitions of alliance efficiency and weak alliance efficiency are developed. The relationship between alliance efficiency and the relevant multiple objective programming non-dominated solution is studied. The properties on projection and efficiency improvement of decision making units are studied, In addition, it provides the measurement solution to the overall efficiency of alliance units and evaluation steps. Lastly, it applies the method to the simulation application.
