【摘要】：近年来,随着港口集装箱吞吐量迅速的增加,如何提高集装箱码头整体的装卸作业效率成为集装箱港口普遍关注的问题,为此一些集装箱港口开始运用新型的装卸工艺。同贝同步装卸工艺正是集装箱码头为提高装卸效率而采用的一种新型的装卸工艺,其特点是:对集装箱船舶同一贝位内的集装箱进行同步的装卸作业,这种装卸工艺与目前传统装卸工艺即先卸后装工艺相比,可以使岸桥作业小车和集卡来回作业都处于重载状态,从而可以提高港口的装卸效率和集卡的利用率,对降低港口运营成本具有重要的意义。虽然该装卸工艺能大大的提高岸桥和集卡的利用率,但如果缺乏相适应的集装箱堆场堆存策略,将会使得该装卸操作不能顺利的进行,也会大大降低此新型工艺的运用效果。因此,为同贝同步装卸工艺选择合适的集装箱堆场堆存策略具有非常重要的意义。本文首先对同贝同步装卸工艺的模式及集装箱船舶的配积载原则进行了分析,在此基础上提出了两种适用于岸边同贝同步装卸工艺的船舶配积载原则即同贝位同箱量和同目的港远贝位,从而更好地支持集装箱码头在实际操作中运用同贝同步装卸工艺;其次,基于传统装卸工艺下集装箱堆场堆存策略和进出口集装箱堆存规则分析的基础上,详细研究了与岸边同贝同步装卸相适应的同船异箱区分开堆存策略、同船同贝位混合堆存策略和同船异贝位混合堆存策略,并对翻箱原则和评估集装箱码头作业的性能指标进行分析,为集装箱堆场堆存策略的比较分析奠定基础;再次,根据复杂的离散事件系统建模技术和概念模型的相关理论,建立了集装箱物流系统动态模型和同贝同步装卸下集装箱码头装卸系统的概念模型,并通过这些模型在FlexTerm仿真平台上构建了同贝同步装卸下集装箱码头装卸系统的仿真模型。最后,本文在FlexTerm仿真平台上对在同贝同步装卸下集装箱堆场堆存策略进行仿真试验,并通过仿真数据深入分析堆场堆存策略对同贝同步装卸工艺效率的影响。试验结果表明:在相同的外部条件下,同船异箱区分开堆存策略能够更好的适应同贝同步装卸工艺的运用。同时,将同贝同步装卸工艺下同船异箱区分开堆存策略与传统装卸工艺下堆场“前出后进”的堆存策略进行对比分析,得出同贝同步装卸工艺下同船异箱区分开堆存策略能够大幅度的提高集装箱码头的装卸作业效率,从而大大的缩短了船舶的在港时间。
[Abstract]:In recent years, with the rapid increase of container throughput, how to improve the overall handling efficiency of container terminals has become a common concern of container ports. For this reason, some container ports began to use new handling technology. Synchronous loading and unloading technology is a new type of loading and unloading technology adopted by container terminal in order to improve loading and unloading efficiency. Its characteristic is that the container in the same shell position of container ship is loaded and unloaded synchronously. Compared with the traditional loading and unloading process, this loading and unloading process can make the loading and unloading of the quayside crane and the loading and unloading operation in the heavy load state, thus improving the loading and unloading efficiency of the port and the utilization rate of the collection card. It is of great significance to reduce the cost of port operation. Although the loading and unloading technology can greatly improve the utilization ratio of the quayside bridge and the collection card, if there is no suitable storage strategy for the container yard, the loading and unloading operation will not be carried out smoothly, and the application effect of the new technology will be greatly reduced. Therefore, it is of great significance to select the appropriate stacking strategy of container yard for synchronous loading and unloading process. In this paper, the mode of synchronous loading and unloading process and the stowage principle of container ship are analyzed. On this basis, two kinds of ship stowage principles suitable for simultaneous loading and unloading technology on shore and shellfish are put forward, that is, the same tank size at the same shell position and the distant shell position in the same destination port, so as to better support the application of synchronous loading and unloading technology in the practical operation of the container terminal. Secondly, based on the analysis of container yard storage strategy and import and export container storage rules under the traditional loading and unloading technology, this paper studies in detail the separate storage strategy of the same ship and different containers, which is suitable for the simultaneous loading and unloading of the same shellfish on the shore. In order to lay a foundation for the comparative analysis of the stacking strategy of container yard, this paper analyzes the principle of turning over the container and the performance index of evaluating the operation of the container terminal by using the mixed storage strategy of the same ship and the same shell and the mixed stacking strategy of the same ship and the different shells of the same ship. The dynamic model of container logistics system and the conceptual model of container terminal loading and unloading system under synchronous loading and unloading are established according to the complicated discrete event system modeling technology and the related theory of conceptual model. Through these models, the simulation model of container terminal loading and unloading system under synchronous loading and unloading is constructed on FlexTerm simulation platform. Finally, the paper carries on the simulation test on the FlexTerm simulation platform to the container yard storage strategy under the same shellfish synchronous loading and unloading, and through the simulation data deeply analyzes the stowage strategy's influence on the same shellfish synchronous loading and unloading technology efficiency. The experimental results show that under the same external conditions, the strategy of separating and storing different containers of the same ship can better adapt to the application of the synchronous loading and unloading technology of the same shellfish. At the same time, the strategy of separating and storing the different containers of the same ship under the synchronous loading and unloading technology of the same shell is compared with that of the "before, out and back" of the yard under the traditional loading and unloading technology. It is concluded that the strategy of separating and storing different containers of the same ship can greatly improve the efficiency of loading and unloading of container terminals, and thus greatly shorten the ship's time in port.
