秦皇岛港航道通过能力仿真研究

采用工程仿真软件SIMIO分别对秦皇岛港10万吨级航道及规划的20万吨级航道的通过能力进行模拟。首先用2014年秦皇岛港泊位和航道设施及到港船舶数据对模型进行验证，得到的年到港船舶数及航道货运量与实际统计结果基本相符；结合仿真结果，对两航道的货运量、船舶平均待泊时间AWT以及港口服务水平随船舶平均到港时间间隔的变化趋势进行分析；讨论了航道及泊位利用率随港口服务水平的变化；针对10万吨级航道，对比了仿真与航道利用率法的年通过能力结果，并指出确定航道通过能力时考虑港口服务水平及港内作业各环节相互关联性的必要性。

Simulation study on capability for waterways of Qinhuangdao port

Simulation models are established for the 100 000 DWT branch and the planning 200 000 DWT branch of Qinhuangdao port by SIMIO simulation software.The model is firstly verified by the data of berth number,waterway facilities and statistics of calling ships of Qinhuangdao port in 2014.Good correspondance between the modeled results and the statistics is obtained in terms of numbers of annual calling ships and the cargo throughput.By changing the average arrival interval of vessels,the variation tendency of the cargo throughput,the average waiting time(AWT)and the service level are investigated based on the simulation results.The variation tendency of the utilization of channel and the berths with the service level is discussed.Comparison is conducted between the results of cargo throughput of the 100 000 DWT branch by simulation model and prediction formula.The necessity is pointed out in terms of taking into account the service level of port and the correlativity among various operations inside a port.
