Research on muli-objective ship speed optimization considering ship emission control areas
Considering the background of emission control area for ships,the multi-objective ship speed optimization is carried out with fuel cost and charter cost as optimization objectives,and two multi-objective optimization methods based on butterfly optimization algorithm combined with linear weighting and multi-objective dragonfly algorithm are selected to solve the Pareto optimal solution set.Finally,the optimal compromise solution is determined from Pareto optimal solution set by the decision method of ideal point distance method.The results show that when the multi-objective dragonfly al-gorithm is used to optimize sailing speed,the fuel cost is reduced by 2.72％,the charter cost is reduced by 15.57％,which can effectively reduce the ship operating cost by 5.78％,and greatly improve the economic benefits of shipowners and shipping enterprises.More in line with the requirements of environmental protection.
