由于集装箱船舶在港作业系统的离散、随机和动态性等特点，使得很难用传统数学分析方法对其进行分析。在集装箱码头船舶作业系统分析的基础上，利用Arena平台建立了由船舶到港模块、锚地待泊和通航模块、船舶靠泊模块、船舶在泊作业模块、集装箱搬运和船舶离港模块等组成的集装箱船舶在港柔性作业仿真模型，并详细阐述了各部分的建模过程和方法，分析了船舶在港作业对港、船方性能指标的影响规律，指出岸桥装卸效率对AWT、AWT／AST的影响变化较大，均呈现指数变化趋势。研究成果可为集装箱港口仿真建模与性能分析提供参考。%The discrete, stochastic and dynamic characteristics of the ship operating system make it difficult to be analyzed using mathematical methods. Based on the analysis of the ship operating system in a container terminal, simulation models of container terminal operations are built through the software of Arena. The models are composed of a ship-to-port module, a waiting-in-anchorage and navigating-into-port module, a berthing module, a loading and unloading in berth module, and a container-handling and ship-leaving module. The modeling process and methods are then explained in detail. The effects of ship operations on the performance of the port and ships are analyzed. It is pointed out that the quayside handling efficiency had a great impact on AWT and AWT/AST, both showing trends of exponential change. The results could provide reference for simulation modeling and performance analysis tbr container terminals.
