摘要
从运输费用最低出发,考虑多式联运型物流网络中不同运输方式的衔接成本与时间、枢纽点间货物运输产生的规模经济效益和服务时间的约束,建立了多式联运型物流网络的货运枢纽选址模型,并运用遗传算法,将问题转化为UFL问题进行求解,最后通过算例进行了验证。该方法能有效地求解带时间约束的多运输方式组合问题,对物流承运商选择最优的运输方式组合具有一定的参考价值。
In this paper, with the minimal transportation cost as the objective, we considered the connection cost and time of different transportation modes, the benefit of economy of scale generated from cargo transportation between logistics nodes and the service time constraint, built the location model of the freight hubs of the intermodal transportation logistics network, and used the genetic algorithm to solve it. At the end, we demonstrated the correctness of the procedure through a numerical example.
