摘要
针对集装箱班轮运输中船舶燃油补给问题,分析船舶航速变化对燃油消耗产生的非线性影响,推导出船舶航速与船舶往返时间及船舶油耗之间的关系式,以连续多航次船舶燃油补给总成本最低为目标,加油港与加油量为决策变量,建立周计划内考虑航速的集装箱班轮燃油补给混合整数非线性规划模型.根据模型特点,利用分段线性逼近函数对模型进行等价转换.以某航运公司的亚欧单航线为仿真实验,依次分析港口时间窗、船舶类型、燃油价格及船舶油舱容量等因素对船舶燃油补给策略的影响.结果表明:该模型可以同时决策船舶加油港的选择、加油量的大小及航速的调整,比传统模式更能节省油耗和成本.
In view of the problems of ship＇s refueling strategy in container liner transportation network,analysis of the non-linear influence of ship speed on fuel consumption is done and the mathematical functions are deduced to describe the relationships between the ship speed,fuel consumption and the round voyage time. To minimize the ship refueling cost,a mixed integer non-linear programming model considering ship speed is formulated to solve the optimal refueling strategy problem of where to refuel and how much to fuel. According to the characteristics of the model,we utilize piecewise linear approximation function for equivalent model. The single shipping liner service of Asia-Europe is taken as an example for the simulation experiment,the sequence analysis is made of port arrival time windows,and ship type,bunker fuel price,and ship bunker fuel capacity on bunker fuel supply strategy. The results indicate that the proposed model,compared with the conventional model,can simultaneously solve the problems of bunkering port,bunkering amounts and ship speeds adjustment,save fuel consumption and cost.
