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 ch
