基于交叉效率 DEA 和熵 IAHP 对物流企业绩效评价

摘要

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 per-formance.The central idea of the cross-efficiency DEA theory is adopted from the peer assessment system.Igno-ring 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 combina-tion of the entropy method determining weights justly and the IAHP method reflecting the decision makers’ pref-erence.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.%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。
