基于交叉效率DEA和熵IAHP对物流企业绩效评价

Study on Logistics Performance Evaluation Based on Cross-efficiency DEA and Entropy IAHP Method

本文在研究了现有文献对物流企业绩效评价的基础上,基于超效率DEA用以计算效率值的权值只在对被评价单元最有利的特定范围内取值、忽视绩效评价的公平性和IAHP方法主观判断性较大的缺陷,提出了交叉效率DEA和熵IAHP方法。交叉效率DEA的中心思想是采用互评体系,弥补了超效率DEA方法只是选择对被评价决策单元最有效的权重忽视公平性的缺陷。熵IAHP方法是客观确定权重的熵权法和体现决策者偏好的IAHP方法的结合,这有效地解决了IAHP方法确定指标权重时主观性过大的缺陷。笔者给出了交叉效率DEA和熵IAHP模型评价物流企业绩效的基本步骤,最后通过一个实例验证了此方法的有效性和优越性。

Based on the study of the existing literatures on the performance evaluation of logistics enterprises, we present the cross-efficiency DEA and entropy IAHP method. Super-efficiency DEA is used to choose the weights of the efficiency value only when the weighs are in the most advantageous position to a decision making unit, which neglects the fairness. IAHP method has the drawback of larger subjective judgments while evaluating performance. The central idea of the cross-efficiency DEA theory is adopted from the peer assessment system. Ignoring the fairness, the super-efficiency DEA method just chooses weights which are favorable for a decision making unit. This drawback can be compensated by cross-efficiency DEA method. Entropy IAHP method is the combination of the entropy method determining weights justly and the IAHP method reflecting the decision makers＇ preference. We present the basic steps of the cross-efficiency DEA and IAHP model when evaluating performance of logistics enterprises. In the end, the applicability and superiority of the method is illustrated by using a real case study.
