In 2017, smaller container ports handled approximately 22% of total containerized cargo. Nowadays liner operators are calling on those ports with larger ships and demanding fast and efficient turnaround of the ships in port. This is possible only if the berth has the right capacities, is working properly and achieves a good productivity level. Productivity level does not depend only on the quay crane capacities but also the transfer mechanisation, of which the main function is to serve quay cranes on one side and yard cranes on the other side. Choosing the correct type and number of vehicles to transfer container units from berth to yard has become a very important decision in every container terminal. In small container terminals yard trucks represents the most common type of transfer mechanization. That is why this research is based on the allocation of the right number of yard trucks to quay cranes in order to assure better productivity levels in the berth and yard subsystems. For this purpose, a discrete-event simulation modelling approach is used. The approach is applied to a hypothetical small container terminal, which includes operations on the berth-yard-berth relation.

在较小的集装箱码头中确定堆场卡车的最佳数量

2017年，较小的集装箱港口处理了大约22％的集装箱货物。如今，班轮运营商正在呼吁拥有较大船只的港口，并要求港口中船只的快速，高效周转。仅当泊位的容量合适，工作正常并达到良好的生产率水平时，这才有可能。生产率水平不仅取决于码头起重机的容量，还取决于转移机械化，其主要功能是为一侧的码头起重机和另一侧的院子起重机提供服务。在每个集装箱码头中，选择正确的车辆类型和数量将集装箱单位从泊位转移到院子已经成为非常重要的决定。在小型集装箱码头，堆场卡车是最常见的转移机械化类型。因此，本研究基于将正确数量的堆场卡车分配给码头起重机，以确保泊位和堆场子系统中更高的生产率水平。为此，使用了离散事件模拟建模方法。该方法应用于假设的小型集装箱码头，其中包括对泊位-泊位-泊位关系的操作。
