【摘要】：铁水联运集装箱堆场的有效管理和调度优化是提高港站这一节点效率的关键。堆场空间资源有效利用虽不会对港站经济效益产生直接影响,但其空间资源调度优化可以减少集装箱在堆场内装卸时间,提高港站核心竞争力,并为提高港站经济效益打下良好基础。本文以铁水联运集装箱港站为载体,以集装箱堆场空间资源为研究对象,针对集装箱堆场箱区分配和箱位指派两个问题,对堆场箱位分配方法进行研究,形成考虑船舶配载要求的堆场集装箱堆存方法。为获得高效合理的铁水联运集装箱堆场箱位分配方法,本文的主要研究内容如下:(1)铁水联运集装箱堆场空间资源优化分析。通过对铁水联运节点作业空间范围进行界定,对集装箱在节点处的作业流程进行分析,指出堆场空间资源评价指标形式包括堆场空间资源利用率、堆场空间资源使用均衡度、集装箱堆场堆存总箱时。在此基础上,分析不同集装箱量的堆存模式的区别,以集装箱在港站内的作业效率为目标,指出在研究周期内适用于每种堆存方式的集装箱箱量大小。(2)集装箱箱区分配优化研究。以最小化集装箱堆存占用箱区贝位数为目标,考虑将属于同一船舶的集装箱集中堆存以方便装卸作业,建立时空范围上的箱区分配模型,船舶堆存区域大小由属于该船舶的集装箱箱量确定。模型从时间和空间两方面对集装箱堆存方法进行优化,即当某一船舶的集装箱尚未到达港站,集装箱尚未堆存在属于该船舶的堆存区域时,这一区域可堆存其他船舶的集装箱;当该船舶到达港站时,这一区域空闲。并设计禁忌搜索算法对箱区分配优化模型求解。(3)集装箱箱位指派方法研究。以最小化集装箱堆存时贝位内压箱量为目标,考虑在进行装船作业时所遵循的配载图,将船舶配载评估因素简化为集装箱终到港和集装箱箱重两个评估因素,在贝位范围内设计箱位指派模型,为集装箱指派较优化的箱位。并借鉴铁路调车作业中的车组下落过程设计算法进行求解。铁水联运集装箱在堆场空间资源进行优化,不仅能够为铁水联运节点调度优化提供理论和现实参考,实现集装箱在港站内堆存资源的优化;而且科学、高效的方式对堆场空间资源进行优化,是进行集装箱铁水联运网络调度优化的前提,也是铁水联运网络调度优化的基础,同时能够为制定铁水联运铁路集疏运组织计划提供依据。
[Abstract]:The effective management and scheduling optimization of the container yard for combined transport of hot metal and water is the key to improve the efficiency of the terminal. Although the effective utilization of the space resources of the yard will not have a direct impact on the economic benefits of the port and station, the optimization of its spatial resource scheduling can reduce the loading and unloading time of containers in the yard and improve the core competitiveness of the port and station. It also lays a good foundation for improving the economic benefit of the port and station. In this paper, the container space allocation method of container yard is studied for two problems: the allocation of container area and the allocation of container space, taking the container terminal as carrier and the space resource of container yard as the research object. Form a stowage container stowage method considering ship stowage requirements. In order to obtain an efficient and reasonable method of container space allocation for hot metal combined transport container yard, the main contents of this paper are as follows: (1) the optimization analysis of space resources of hot metal combined transport container yard. By defining the working space scope of hot metal-water transport nodes and analyzing the operation process of containers at the nodes, it is pointed out that the evaluation index forms of the yard space resources include the utilization rate of the yard space resources and the equilibrium degree of the yard space resources use. When the main container is stored in the container yard. On the basis of this, the paper analyzes the difference of storage mode of different container volumes, aiming at the efficiency of container operation in port and station. It is pointed out that the container volume is suitable for each storage mode in the research period. (2) the optimization research of container area distribution. In order to minimize the number of bins in the container storage area, the container storage belonging to the same ship is considered in order to facilitate the loading and unloading operation, and the allocation model of the container area in the space-time range is established. The size of the ship's storage area is determined by the container volume belonging to the ship. The model optimizes the method of container storage in both time and space, that is, when the container of a certain ship has not arrived at the port station and the container has not yet been stacked in the storage area belonging to the ship, the container in this area can be stored in the container of other ships; When the ship arrives at the port station, the area is idle. The Tabu search algorithm is designed to solve the optimization model of box allocation. (3) the container location assignment method is studied. With the aim of minimizing the quantity of shellfish in container stowage, considering the stowage diagram followed in the course of loading operation, the assessment factor of ship stowage is simplified to two factors: container final arrival and container weight. Design the box space assignment model in the shellfish range, assign the optimized container space for the container. And draw lessons from the train shunting operation of train fall process design algorithm to solve. The optimization of the space resources of hot metal combined transport containers in the yard can not only provide theoretical and practical reference for the scheduling optimization of hot metal combined transport nodes, but also realize the optimization of container storage resources in the port and station. Moreover, the scientific and efficient way to optimize the space resources of the yard is the premise of the scheduling optimization of the container combined hot metal transport network, and is also the basis of the scheduling optimization of the hot metal combined transport network. At the same time, it can provide the basis for drawing up the organization plan of railway collection and distribution of hot metal-water combined transport.
