Abstract: To optimise vessel scheduling passing a compound channel with the water depth influenced by the periodic tide, this study establishes the vessel scheduling model through a typical tidal compound channel. In addition, based on the actual tidal data of the channel, a tide height computation function varying with time is obtained. Then a designed genetic algorithm (GA) is utilised to verify the model by the actual vessels' data through the Tianjin Port Fairway. The test experiment shows that the organisation efficiency is better than other methods, including larger draft vessels first (LDF), first come first served (FCFS), random scheduling (RS) and manual scheduling. It can take full advantage of the high tide and improve the vessel scheduling efficiency of a compound channel. With minor alterations, the proposed model and designed algorithm can also serve for vessel traffic organisation in other compound channels affected by tide water as well.
