Aiming at the selection of refueling ports, the amount of refueling, and the speed selection faced by ships in container liner transportation, taking into account constraints such as carbon emissions, fuel consumption, vessel tank capacity, speed selection, and arrival time window, a fuel replenishment optimization model considering liner speed selection was established with the goal of minimizing vessel fixed costs, fuel costs, and carbon tax costs. An improved linear approximation method is proposed to transform the model into an equivalent linear programming model to obtain the optimal solution. Finally, using a real case study of a shipping company as an example, this paper analyzes the influence of error precision change, arrival time window and fuel price on the decision-making of shipping companies, verifying the effectiveness and practicality of the model and algorithm constructed in this article. The results show that the new method can effectively improve the efficiency and accuracy of calculations, and reduce the operating costs of shipping companies.
