船舶到港时间可变的泊位—岸桥联合调度

Berth and quay cranescheduling based on variable arrival time of ship

为研究不同靠港计划对船舶燃油消耗和码头碳排放量的影响,分别建立了船舶到港时间可变(variable arrival time,VAT)和到港时间固定(constant arrival time,CAT)策略下的泊位—岸桥联合调度模型,以最小化船舶延迟离港时间、航行油耗和整个码头碳排放为目标进行多层次对比分析。研究结果表明:与CAT策略相比,VAT策略可以在同等或略微降低码头服务水平的前提下,大幅度减少船公司航行油耗和整个码头的碳排放。在目前节能减排的趋势下,采用VAT策略不但可以为船公司节省运输成本,还可以保护环境,低碳运营。

In order to study the influence of different port plan on vessel fuel consumption and carbon emission of wharf,two models of berth and quay crane scheduling,with the strategy of variable arrival time（ VAT） and the one of constant arrival time（ CAT）,are set up respectively.Multi-level comparative analysis of the models is made with the goals of minimizing delayed departure time of ship,fuel consumption and carbon emissions from the terminal. The research results show thatthe VAT strategy can significantly reduce fuel consumption and carbon emissions under the condition of equal or slightly lower terminal service level,compared to the CAT strategy. At present,under the trend of energy saving and emission reduction,adopting VAT strategy can not only save the cost of transportation for shipping company,but also protect the environment and operate in low-carbon mode.
