摘　　要：船舶进出港安全时距是控制同向进出港船舶尾随时间的安全参数,是关系到沿海港口服务水平的重要因素之一。目前国内部分散货港区由于单向航道通过能力的限制,导致港口服务水平严重下降,为缓解航道拥堵、提高港口服务水平,利用Arena软件构建港口生产作业系统的仿真模型,研究安全时距的变化对港口服务水平的影响,并应用于具体工程案例的仿真模拟和相关分析。试验结果表明:针对规模较大港区通航历时较短的单线航道,适当减小船舶进出港安全时距,能在一定程度上提高其港口服务水平。As one safety parameter to control the dangle-after time of ships which enter and leave port in same direction,the safe time-interval of ship entering and leaving port is one of important factors affecting the service of coastal port.Nowadays,the service of some bulk cargo ports descends sharply due to the limited navigable capacity of one-way channel.To mitigate the channel traffic jam and improve the port service,Arena software is applied to constitute the simulation model of port operating system and study the impact of safe time-interval on the port service.The above is also applied in the detailed projects simulation and the relevant analyses.It is shown in the test that the suitable reduction of safety time-interval may improve to some extend the port service for the one-way channel with shorter navigable history in a large-scale port area.
