Abstract: In order to optimize the allocation of resources of liner ship companies, a fleet deployment model based on biobjective programming was established to minimize the total costs of shipping operation and carbon dioxide emissions in the planning period. And then the model was solved by Gurobi. The feasibility and effectiveness of the model was verified by numerical experiments. Computational results show that comparing with ones with smaller capacity, the ship with large capacity is more competitive in single box cost and generates less carbon dioxide emissions, which will be better for the environment protection. Three methods of ship capacity structure, such as reducing the ship’s fuel consumption constants by improving the ship technology, slow steaming and the main configuration of large ship, are effective measures to significantly reduce ship operation costs and carbon dioxide emissions.

摘要： 为了优化班轮公司的船舶资源配置，以规划周期内船舶运营总成本和碳排放量最小化为目标，建立了一个双目标规划航线配船模型，使用Gurobi工具对模型进行求解，通过数值实验对模型的可行性和有效性进行验证。研究表明：同更小容量的船舶相比，大容量船舶不仅具有单箱成本的竞争优势，而且排放更少的CO2，更加有益于环境保护；通过提升船舶的技术以减少船舶的燃油消耗常数、减速航行以及配置大型船舶为主的运力结构这3种方法是显著减少船舶运营成本和碳排放量的有效措施。
