【摘要】 以带时间窗的多式联运模型为基础,考虑节点间的运输时间、节点处的运输方式转换时间以及可能发生的货运延迟,以包括运输成本、转运成本和时间偏离惩罚成本在内的总成本最小为目标函数,建立基于满意时间路径的多式联运模型。在算法上,构造了基于K最短路的改进遗传算法,通过3个算例说明多式联运的运输路径与运输方式搭配可以不是唯一的,为多式联运的相关研究工作提供了理论基础。更多还原

【Abstract】 Based on multimodal transportation with time windows,taking into consideration the transport time between nodes,time needed for mode change,and possible transport delay in multimodal transportation networks,a model for multimodal transportation was constructed to minimize the total cost that included transportation costs and transfer costs.A betterment Genetic Algorithm was constructed based on K-shortest-paths.Three examples were used to show that there are more than one combination between path of transport and way of transport.This provides a theoretical foundation for relevant research on multimodal transportation.更多还原
