基于第三方物流的集成化物流网络系统优化设计研究

3PL-Based Integrated Logistics Network Optimization

考虑利用第三方物流商提供的设施构建物流网络,建立了一个多目标模型,同时优化物流成本和服务水平,确定物流网络中设施的数量、位置以及产品运输路线和运输量,从而建立企业的物流网络系统。通过定义每个目标的隶属度函数,将模型转化为最大化决策者的满意度从而求解模型,算例分析说明了模型的有效性。

Based-on the concept of 3rd part logistics,the logistics network optimization problem for a manufacturing enterprise is discussed.With both logistics cost and service level taken into account,a multi-objective integer programming model is presented.In order to solve this model,the satisfactory levels of the objectives are defined such that the problem can be converted into decision maker＇s different preference problem.An example is given to illustrate the effectiveness and application of the proposed method.
