基于双向运输的集装箱物流系统的优化研究

The Optimization of the Bidirectional Transport of Container Logistics System

本文根据集装箱的不同信息来确定其优先属性;并用一个具体的数值来表示,对于进口箱根据堆存时间与客户距离的远近确定属性值,对于出口箱则根据目的港距离的远近与重量级别确定集装箱属性值,根据属性值低可压属性值高的原则为集装箱分配合适的箱区和船舶贝位,考虑道路约束的限制,建立"作业面"下的集卡路径优化模型得出各箱区堆存的进口箱量和船舶各贝位装载的出口箱量及最少集卡配置数量,并给出集卡运送路径上的车次限制.最后通过算例应用lingo软件求解验证了模型的有效性,提高了堆场效率.

The priority of the container is determined according to different aspects which are mixed with the level of weight; Taking for this priority in a specific numerical attributes;for import containers the attribute value is consist of the weight and the time when the clients come to take it; for export containers the attribute value is consist of the weight and the destination where it will be taken to; and establishing the container trucks transporting model on the mode of the pool strategy by comprising the application of attribute values for container distribution suitable area and ship bay; Then get the number of containers in different modules of the yard and the limit of transport paths of the trucks between the yard and ship.Finally verified by an example and get the solution with Lingo software in the paper,set about container terminal port card the effectiveness of the scheduling and improve the efficiency of the yard.
