多式联运是交通运输发展的高级阶段,是现代交通运输发展的一种必然趋势。文中建立了一个考虑货物运输所需费用、时间以及货物数量等因素的多式联运运输网络模型,将模型转化为线性规划问题。首先求解出最短运输路径,然后利用软件LINGO求解得到较优的运输方式,从而使得多式联运运输成本和运输时间达到最低。 Multimodal transport is an advanced stage of transportation development and an inevitable trend of modern transportation development. In this paper, a multi-modal transportation network model considering the cost, time and the quantity of goods is established to convert the model into a linear programming problem. First solve the shortest transport path, and then use software LINGO solution to get better mode of transport, so that multimodal transport costs and transport time to a minimum.
