【摘要】：在规模经济的推动下，船舶不断朝着大型化发展，港口建设不断朝着深水化发展，集装箱运输量不断地扩大。伴随着港口吞吐量的增加，增加装卸设备数量可以提高泊位装卸效率，减少船舶在港时间，，减少船方在港成本，同时增加港口吞吐量，使港方获得更多的经济效益。但是当装卸设备数量达到一定程度后，船舶在港时间将不再继续减少，为了使船舶平均在港时间继续减少，港口只有增加新的泊位，但是装卸设备和泊位的增加意味着港方投资的增加。因此，本文通过确定港口最佳泊位数和最优装卸机械数量，实现了港、船双方综合效益的最大化，为港口的扩容改造，规划新建提供参考。本文首先简要地介绍了集装箱码头的装卸机械、堆场以及装卸工艺，说明了排队论在集装箱码头装卸系统中的应用，并通过理论推导，求解出装卸系统中的各项评价指标。之后，介绍了计算机仿真技术，并阐述了仿真技术在集装箱码头系统中的应用。本文运用仿真软件Arena建立了集装箱码头装卸系统的仿真模型，介绍了建立模型的流程，详细叙述了各个作业系统中的模块，给出了各模块中仿真参数的确定方法以及最终结果。通过对仿真模型进行试验，得出了以下结果。当泊位数固定，单泊位岸桥数为最优岸桥数时，以船舶平均在港时间为主要控制条件，以AWT/AST为次要控制因素，通过设计不同的场桥数和集卡数的组合，按照某一特定的选取原则，得到了不同设计年吞吐量情况下的最优场桥数和集卡数，并对该结果进行了分析。当泊位数不定时，在泊位数和单泊位岸桥数最优联合配置的基础上，进一步进行了泊位、岸桥、场桥、集卡的联合配置，从而得到了泊位与装卸机械的最优联合配置结果。最后阐述了本文研究中存在的一些缺点和不足，并指明了进一步研究的方向。
[Abstract]:Under the impetus of economies of scale, ships continue to develop on a large scale, port construction moves towards deepwater, and container traffic continues to expand. With the increase of port throughput, increasing the number of loading and unloading equipment can improve the handling efficiency of berth, reduce the time of ship in port, reduce the cost of ship in port, increase the throughput of port, and make the port get more economic benefits. However, when the number of loading and unloading equipment reaches a certain level, the ship's time at the port will not continue to decrease. In order to make the average ship's time at port continue to decrease, the port will only have to add new berths. But the increase in handling equipment and berths means an increase in investment from the Hong Kong side. Therefore, by determining the optimum number of berths and the optimal number of loading and unloading machinery, this paper maximizes the comprehensive benefits of both ports and ships, and provides a reference for the expansion and transformation of ports and the planning and construction of new ports. In this paper, the loading and unloading machinery, yard and technology of container terminal are introduced briefly, the application of queuing theory in container terminal loading and unloading system is explained, and the evaluation indexes of loading and unloading system are solved by theoretical derivation. Then, the computer simulation technology is introduced, and the application of simulation technology in container terminal system is expounded. In this paper, the simulation model of container terminal loading and unloading system is established by using the simulation software Arena, the process of establishing the model is introduced, the modules of each operation system are described in detail, and the method of determining the simulation parameters and the final results are given. The simulation model is tested and the following results are obtained. When the number of berths is fixed and the number of single berths is the optimal number of shore bridges, the average ship's time in port is taken as the main control condition and AWT/AST as the secondary control factor. According to a particular selection principle, the optimal field bridge number and set number of cards are obtained under different design year throughput conditions, and the results are analyzed. When the number of berths is unfixed, on the basis of the optimal joint allocation of berths and single-berth quayside bridges, the joint allocation of berths, quaybridges, field bridges and collecting cards is further carried out, and the optimal joint allocation results of berths and loading and unloading machinery are obtained. At last, some shortcomings and shortcomings in this paper are discussed, and the direction of further research is pointed out.
