Abstract: Under the carbon tax mechanism, considering the special nature of perishables, it is an important decision for shipping companies to optimize liner speed and formulate fueling strategies. From the perspective of shipping companies, a mixed integer nonlinear programming model was established to achieve the minimum total cost of liner operation including fixed costs of ships, fueling costs, asset decay cost, refrigerated costs and carbon taxes. According to the characteristics of the proposed model, the piecewise linear approximation method was used to linearize and solve the fuel consumption function and perishable product deterioration function. Taking the actual liner route as an example, the effects of port fuel price, arrival time window and carbon tax rate on the decision-making of shipping companies were analyzed in turn. The research results can provide scientific basis for container liner companies transporting perishables to choose refueling ports, determine refueling volume and optimize speed.
