摘　　要：为提高液化天然气(Liquefied Natural Gas,LNG)船舶进出港效率,考虑影响进出港效率的多种外界干扰因素,将干扰排队模型运用到进出港交通组织方案的仿真分析中.通过仿真分析结合实例对该模型进行检验.结果表明,该模型能较好地模拟航道船舶的通过状况.该方法可为LNG船舶进出港效率评价提供重要的技术手段.To improve the efficiency of Liquefied Natural Gas （LNG） carrier entering and leaving port, considering a variety of outside interference factors with impact on the efficiency, the queueing model with interference is applied to simulation analysis on the traffic organization scheme of ship entering and leav- ing port. The model is verified by simulation analysis combined with examples. The results show that the model can simulate navigation process of ships in channels better. The method provides an important technical means for efficiency evaluation of LNG carrier entering and leaving port.
