考虑岸电约束的港口电动拖轮调度研究OA

In line with the development trend of new energy-powered tugboats in port operations,a mixed-integer linear programming model for scheduling electric tugboats is established with the objective of minimizing task delay costs,conventional tugboat fuel consumption costs,and electric tugboat electricity consumption costs,while considering the constraint on port shore power facilities.A solution method based on the salp swarm algorithm is proposed,and its effectiveness and accuracy are verified through comparison with the Gurobi solver.Finally,sensitivity analysis is conducted to examine the impact of the number of charging guns and the charging rate per unit time on operational costs.The case study results show that through reasonable scheduling of electric tugboats,not only can port operating costs be reduced,but the number of charging guns required for construction can also be minimized,thereby lowering construction costs.
