Throughput Capacity of a Container Terminal Considering the Combination Patterns of the Types of Arriving Vessels

The throughput capacity of a container terminal is very important in planning and designing at container terminals.The existing methods estimated the throughput capacity without considering its change resulting from the different combination patterns of the types of arriving vessels.A simulation model is established to estimate the throughput capacities of a container terminal under different combination patterns of the types of arriving vessels.It shows that the throughput capacity of a container terminal is influenced by the utilization rates of the berth and quay cranes which result from the different combination patterns of the types of the arriving vessels.It provides a practical approach to estimate the throughput capacity of a container terminal considering the types of the vessels,and it is also helpful for the decision makers to raise the throughputs of the container terminals by optimizing the combination patterns of the types of arriving vessels.

考虑柔性靠泊的集装箱码头合理岸线利用率分析

为描述集装箱码头柔性靠泊方式下的泊位岸线利用情况,引入岸线利用率的概念,给出影响其合理取值的主要因素;结合我国集装箱码头的建设、运营情况,对其中两大因素岸线规模和到港船型进行重点分析;并通过仿真技术求得不同组合下的合理岸线利用率。结果表明,与泊位利用率相比,岸线利用率更能反映集装箱码头的实际生产情况;且岸线越长、到港船型越大,其合理取值越高。
