Abstract: Qinzhou Port, one of the largest in the Beibu Gulf, had a throughput of over 170 million tonnes and a container throughput of more than 5.4 million TEUs in 2022. The port is currently considering adopting the "seamless-connection mode" scheduling strategy to improve the operational efficiency of container ships. However, quantitative analysis tools are lacking. Using AnyLogic simulation software, this study has created a simulation model of the entire process of arriving at the port, waiting at the anchorage, entering the channel, anchoring, and leaving the port, both under the 'seamless-connection mode' and the existing scheduling modes for container ships at Qinzhou Port. The simulation results show that, compared with the existing scheduling mode, the average waiting time for container ships is reduced by 50.7%, while the threshold value for harbour service ships can be increased by 19.5%. These results provide port authorities with the necessary theoretical and data-driven support to formulate relevant policies and traffic rules.
