摘要
通过对已有运输和仓储优化模型的分析,针对现代物流配送网络的特点,提出了基于储运一体化的非线性二级网络配送模型.并构造了具有能力与需求约束、费用与距离综合目标函数的非线性数学规划模型,求证了最优解,并提出算法实现的步骤,最后用实例对算法进行了验证.该问题的提出与算法的可行,为研究多阶段、多路线、多目标的物流配送模型找到了更好的途径.
Based on analyzing the existing models of transit and inventory and the characters of a modern logistics distribution network, a nonlinear two-layer distribution network model was put forward from an integrated transit-inventory concept, and a non-linear programming model, with the restriction of capacity and requirement and the objective function of transport cost and distance, was proposed. Furthermore, its optimum solution was proved, and the calculational process for the algorithm was given. Finally, the algorithm was verified by using an actual example. The result shows that the research is useful to establishing the model of multi-phase, multi-line and multi-target logistics distribution.
