To address issues such as high manual involvement,poor real-time performance,and low efficiency in the scheduling of Gaogang ship lock,this study conducts research on ship lock scheduling strategies under the constraint of ship draught.Firstly,by integrating the greedy strategies of the BLF and HR algorithms,a berthing arrangement method that meets the actual operational needs of Gaogang ship lock is proposed which solves the problems of low flexibility and large space waste,effectively improving the utilization rate of the lock chamber area.Secondly,based on real-time ship perception data and real-time water level in the lock chamber,a dynamic scheduling model for the ship lock is constructed and solved.By automatically generating ship scheduling and dynamically updating plans according to the actual conditions of ships,on the one hand,it can reduce the manual operation volume of ship lock scheduling,and on the other hand,it can reduce the time consumption,thereby improving the navigation efficiency of the ship lock.Finally,through case verification and analysis,the results show that compared with 2024,the utilization rate of lock chamber area and the average lockage time of ships have increased by 13.73% and 17.39% respectively.
