Integrated optimization of traffic organization and berth allocation for two-way navigable ships entering and leaving the port

In order to solve the problems of ship demurrage and berth resource waste caused by ship traffic organization and berth allocation methods in some two-way navigation ports, this paper integrates and optimizes ship traffic organization and berth allocation in two-way navigation ports, specifically considering ships attributes, berth status, port navigation rules and ship traffic conditions, a mixed integer linear programming model is established, and a diploid genetic algorithm is designed to solve the model. Finally, an example is used to test the model and algorithm. The results show that the proposed model and algorithm can provide a feasible plan for ship entry and exit organization and berth allocation under the condition of ensuring safety, and effectively improve the efficiency of ship entry and exit.
