集装箱多式联运是一种以实现货物整体运输的最优化为目标的联合运输的组织形式,而集装箱多式联运系统中各种运输方式的优化组合直接关系到货物运输的费用、时间和运输质量.文中对集装箱多式联运系统中各种运输方式的组合优化问题建立了满足现实约束条件的基于动态规划的优化模型,进行了基于MATLAB的算法与程序设计,获得了最优的运输方式组合策略.实证研究显示了该模型与方法的可行性与有效性.
Container multimodal transport is a form of transport that aims to optimize the whole cargo carriage process,while optimized combination of transport modes has a direct effect on cost,time and quality of the cargo carriage.The optimization problem of the combination of transport modes for a container multimodal transport system is formulated to be a mixed integer programming problem at first.Then,a dynamic programming algorithm is proposed to obtain the optimal combination strategy of transport modes.The corresponding program is designed based on MATLAB and has implemented on a personal computer.Finally,a real life problem was solved to show the feasibility and efficiency of the proposed model and algorithm.
