铁路货运站点整合布局优化研究

摘要

In this paper, considering the constraint in meeting freight transportation needs, the constraint of operational capacity of the railway freight terminals, and the constraint of resource integration of the terminals, and with minimized transportation cost and integration cost as the objective, we established the model for the integration and layout optimization of the railway freight terminals. Since this model was a mixed integer programming model, we used the ILOG software to solve it. Finally in a numerical example, we demonstrated that the idea and method of optimization proposed in this paper could provide reference in decision-making of the terminals.%考虑货运需求满足约束、铁路货运站点的作业能力约束和货运站点整合资源约束,以最小化运输费用和货运站点整合费用最小为目标,构建了铁路货运站点整合布局优化模型.鉴于该模型为混合整数规划模型,采用ILOG优化软件进行求解.算例结果表明,提出的优化思想和方法可对铁路货运站点的布局优化提供决策依据.
