调度是制约支线集装箱运输质量和效率的主要瓶颈之一。针对轴辐射海上运输模式,扩展了陆上车辆运输调度(VRP)理论,以所有船舶总的航行成本最低为目标函数,考虑了软时间约束等现实因素,构建了包含枢纽港和喂给港、多航线、多船型的支线... 调度是制约支线集装箱运输质量和效率的主要瓶颈之一。针对轴辐射海上运输模式,扩展了陆上车辆运输调度(VRP)理论,以所有船舶总的航行成本最低为目标函数,考虑了软时间约束等现实因素,构建了包含枢纽港和喂给港、多航线、多船型的支线集装箱船舶调度模型。基于该问题解的特征运用粒子群算法对模型进行了求解,最后通过仿真算例分析验证了模型的合理性及算法的有效性。 展开更多

Maritime transportation is one of the most important and extensive transportation modes in the world. Maritime transportation is the backbone of contemporary world trade and therefore special attention should be paid to all subjects concerning this mode of transportation. It is also necessary to complement maritime transportation by other modes, such as rail and/or truck (road). This article deals with the problems of maritime transportation and provides the summary of recent developments, trends and statistics mainly on transatlantic maritime routes (Europe to US). Besides maritime transportation, this thesis also reviews the trends and statistics of rail and truck (road) transportation in US and Europe. The authors considers four Czech biggest cities (points of origin), five European ports, eight US ports and 10 biggest cities in US (points of destination). The adapted TCMMSP (transnational collaborative multi-mode shipping problem) is applied to this case study and it seeks to solve the transportation of a set of five shipments with unique O-D (origin-destination) pairs and volume. The end of the thesis summarizes the results and analyses the average costs, optimal set volume, optimal shipment routing and port analysis. 展开更多
