Study on Multi-Objective Optimization of Ship Refueling in Naval Docks
The increase in the number of ships,the improvement of performance,and the increase in tasks have made them face an important issue of optimizing dock fuel supply.For this problem,a multi-objective optimization model of ship refueling at dock was established with ship berth assignment as variables.In this model,refueling time,berth utilization rate and personnel efficiency were the optimization goals.Second,an optimization algorithm for the ship refueling at dock was designed based on the NSGA-II.Then,the application of this optimization model was ana-lyzed through a case study,and its results show the effectiveness of the proposed method.Finally,the selection of opti-mal berth assignment schedules for different tasks was discussed,whereas the optimization of the refueling sequence of ships at the same berth was also explored.
