基于格序理论的供应链金融中物流企业优选

Optimization of Logistics Enterprise in Supply-chain Finance Based on Lattice-order Theory

供应链金融中第三方物流企业的优选问题直接关系到节点企业以及整个供应链的持续稳定运转。根据银行在选择物流合作伙伴时所面临的不确定性和多目标间的不可公度性,首先运用证据距离理论计算各评价指标可信度,据此确定指标权重;其次将正、负加权理想解结合运用,构造拥有顶元素和底元素的概念格;最后用加权Kaufmann距离计算备选企业与理想企业之间的差距,完善以往的格序决策方法,并通过具体算例分析了该方法在供应链金融物流企业优选方面的适用性。

Optimization of 3PL in supply - chain finance is directly related to continuous and stable operation of the node en- terprises and the entire supply chain. According to the uncertainty and incommensurability among multi - objectives which bank faces when choosing logistics partner, firstly, evidence theory is used to determine the weight of each index on the basis of calcu- lating credibility of the indexes; secondly, applying weighted positive and negative ideal solution to the paper to construct the concept -lattice with top and bottom elements; then calculating the gap between the alternative enterprises and the ideal one by using weighted Kaufmann distance, to perfect previous lattice - order method, and analyzing the applicability of the method on selection of logistics enterprises in supply- chain finance through the concrete example.
