为完善锚地规模论证分析理论,考虑航道状态对船舶通航的影响,将锚地和泊位相结合建立船舶离散状态转移模型,并对港口服务系统进行计算机仿真.基于船舶到港、泊位服务时间分别服从泊松与负指数分布,在不同锚地规模、泊位数及其服务效率下,分别计算船舶排队队长、排队概率与船舶锚泊时间,并讨论港口服务能力.仿真结果对港口服务能力的合理规划和组织具有重要的指导意义. In order to improve the theory of anchorage scale argumentation and analysis, considering the influence of waterway condition on ship navigation, the ship discrete state transition model was established by combining anchorage and berth, and the computer simulation of port service system was carried out.According to the ship arrival time and berth service time, Loose and negative exponential distribution, the ship queuing captains, queuing probability and ship anchoring time are calculated separately under different anchorage sizes, berth numbers and service efficiency, and the port service capability is discussed. The simulation results have the following characteristics: Important guiding significance.
