Abstract: The development of low-carbon economy will inevitably bring challenges to the shipbuilding industry , shipping industry and other related industries in the aspect of costs , benefits , technologies and management. With the features of liner shipping operation and the existing power function relationship between speed , the fuel consumption and carbon emissions of ships , the essence of compiling liner shipping schedule under low-carbon economy was to determine the navigation time between different ports within the given voyage time. It is the thing to find the optimum vessel speed between different ports which aimed at reducing the fuel consumption and carbon emissions and meeting the required time. This problem was described. The vessel speed in different routes/ segment was taken as the decision variable and average voyage fuel consumption was taken as optimization objective. A mathematical model was established to describe the continuous dynamic system of liner shipping. It is concluded that in given voyage time , the same vessel speed in each route segment minimize the fuel consumption and carbon emissions in the whole voyage.

Key words: low-carbon economy, liner shipping, liner schedule, vessel speed

摘要： "低碳经济"的发展将不可避免地对造船、航运及相关配套产业在成本效益、技术、管理等方面带来挑战。鉴 于船舶的燃油消耗量和碳排放量与航速之间存在着幕函数的关系及班轮运输营运的特点，在航次时间确定的情况 下，低碳经济下班轮船期表的编制实际上就是要确定船舶在各挂靠港间的运行时间，也即寻求船舶在各相邻挂靠港 之间营运的最优航速，使其在满足航程时间要求的前提下，尽可能的减少航次的燃油消耗量和碳排放量。在对问题 进行描述的基础上，将船舶在各航段的航速作为决策变量，以船舶平均航次燃油消耗量最小作为优化目标，用数学 模型描述了班轮运输这个连续的动态系统，并用数学的方法证明了各挂靠港间或者各区段间采用相同的航速，将使 整个航次的燃油消耗总量及碳排放量达到最低。
