【摘要】：随着港口货物吞吐量的持续增长,以集装箱为代表的标准化运输迅速发展,这对承担港口集装箱集散运输功能的集疏运系统提出了更高的要求。甩挂运输的出现能够有效解决当前港口堆场与内陆腹地间的集装箱集散运输中,内陆腹地装卸货点存在的装卸能力不足及运输过程中存在的运输效率低下等问题。但想要真正发挥甩挂运输的优势,必须解决好甩挂运输中的核心问题—车辆调度问题,本文正是基于以上背景展开研究。首先,本文对车辆调度问题,集装箱运输调度问题,甩挂运输及其调度问题的国内外研究现状进行了梳理,分析了集装箱运输调度和甩挂运输调度的研究成果,阐明了本文的研究内容。其次,本文对港口堆场与内陆腹地间的集装箱甩挂运输进行了研究,阐述了集装箱甩挂运输的内涵和特点。通过对港口堆场与内陆腹地间的集装箱甩挂运输流程进行分析,总结了集装箱进出港甩挂运输中牵引车的运输任务类型,说明了开展集装箱甩挂运输的关键是解决好牵引车的调度问题。然后,在充分考虑集装箱甩挂运输作业特点的基础上,建立了港口堆场与内陆腹地间的集装箱甩挂运输调度模型,并利用改进的贪婪算法对建立的模型进行求解。最后,本文设置了相应的算例对模型进行验证,分别求得了甩挂运输模式下和传统运输模式下的车辆调度方案。在完成相同运输任务的前提下,对比了两种模式下的牵引车的使用数量、单车完成的运输任务数量,以及两种模式下的总运输成本。结果显示,完成相同运输任务的前提下,相比于传统运输模式,甩挂运输模式能够有效节约牵引车使用数量,甩挂运输模式下单车完成的运输任务量高于传统运输模式下单车完成的运输任务量,甩挂运输能够有效地降低运输总成本。
[Abstract]:With the continuous growth of port cargo throughput, the standardized transportation represented by containers has developed rapidly, which puts forward higher requirements for the collection and distribution system which undertakes the function of container collection and distribution in port. The emergence of drop-and-hang transport can effectively solve the problems of container collection and distribution between the port yard and inland hinterland, the shortage of loading and unloading capacity in inland hinterland and the low transportation efficiency in the process of transportation. However, if we want to give full play to the advantages of dump transport, we must solve the core problem of dump transport-vehicle scheduling problem. This paper is based on the above background to carry out research. Firstly, this paper combs the research status of vehicle scheduling problem, container transport scheduling problem, dump-hang transport and its scheduling problem at home and abroad, and analyzes the research results of container transportation scheduling and dump-hang transport scheduling. The research contents of this paper are expounded. Secondly, this paper studies the container dump transport between port yard and inland hinterland, and expounds the connotation and characteristics of container dump transport. Based on the analysis of the container dump transport process between the port yard and inland hinterland, this paper summarizes the types of transport tasks of the tractors in the container dumping and hanging transport in and out of the port. It is pointed out that the key to developing container dump and hang transport is to solve the scheduling problem of tractors. Then, on the basis of considering the characteristics of container dump and hinterland, a container dump transport scheduling model between port yard and inland hinterland is established, and the improved greedy algorithm is used to solve the model. Finally, the corresponding examples are set up to verify the model, and the vehicle scheduling schemes are obtained under the drop-and-hang mode and the traditional transport mode respectively. On the premise of completing the same transportation task, this paper compares the number of tractors under the two modes, the number of transportation tasks completed by the bicycle, and the total transportation cost under the two modes. The results show that, on the premise of completing the same transportation task, compared with the traditional transport mode, the drop-and-hang transport mode can effectively save the number of tractors used. Compared with the traditional transport mode, the total transportation cost can be effectively reduced by the drop-hang transport, which is higher than the single-cycle transport task under the traditional transport mode, and the total transportation cost can be reduced effectively by the drop-off transport mode.
