The relationship between container location dispersion for a single loading and the efficiency of quay cranes (QCs) was investigated. For this purpose, a discrete-event-based simulation model was developed to capture the container-handling process at a transshipment container terminal. A series of experiments were conducted to illustrate the effects of container location dispersion on the long-term performance of QCs and container allocation. These experiments showed that the container location dispersion has a significant effect on the distribution of loading containers. An optimal choice of container location dispersions can improve the efficiency of the QC and help to manage uncertainty at a lower cost. It is suggested that yard managers consider the workload of each berth when deciding on the location dispersion for a loading service. In addition, it was found that optimal container allocation dispersion reduces the congestion caused by time window conflicts and insufficient available equipment.

集装箱位置分散对码头起重机性能的捕获效应

研究了单次装载的集装箱位置散布与码头起重机（QC）效率之间的关系。为此，开发了基于离散事件的仿真模型来捕获转运集装箱码头处的集装箱装卸过程。进行了一系列实验，以说明容器位置分散对质量控制的长期性能和容器分配的影响。这些实验表明，容器位置的分散对装载容器的分布有重要影响。容器位置分散体的最佳选择可以提高QC的效率，并有助于以较低的成本管理不确定性。建议在决定装载服务的位置分散时，堆场管理人员应考虑每个泊位的工作量。
