为解决班轮运输船舶选择哪个港口进行燃油补给、燃油补给量以及各航段最优航速的问题，考虑船舶通过运河时对航速的影响与到港时间窗限制，建立以总成本最小为目标的燃油补给与航速优化模型.选择实际班轮航线进行算例分析，结果验证了模型的有效性.将考虑运河航速影响与不考虑运河航速影响的优化结果进行对比发现，考虑运河对航速影响时解得的燃油补给港选择、燃油补给量以及各航段最优航速的优化结果与客观实际相符，且有助于最小化航运企业总成本，表明该方法有助于航运企业结合航线实际情况合理地制定燃油补给决策以及航速优化方案，保障运输服务.

In order to solve the problems of bunkering ports selection, bunkering amounts determination and the speed optimization in each leg of the liner shipping, considering the influence of ship passing through the canal on speed and the time window limitation, and the refueling and speed optimization model aiming at minimizing total cost was established. The analysis was carried out for actual liner shipping routes to verify the validity of model. As comparing the optimization results of considering the influence of canal on speed with that of non-canal on speed, it was found that the optimized results of bunkering ports selection, bunkering amounts determination and the voyage speeds optimization in each leg are consistent with the objective reality when considering the influence of the canal on speed, and also help to minimize the total cost of shipping companies, which shows that the proposed method is contribute to shipping enterprises to make fuel replenishment decision and speed optimization plan reasonably according to the actual situation of shipping routes, and to guarantee transportation services.
