船舶排放是港口污染的主要组成部分之一。航道管理不力不仅会增加船舶的等待时间，还会加剧港口的排放。将船舶在港调度优化与减速相结合，提出了一种新的船舶减速调度方法(SSSR)。通过三种不同策略下基于航行安全的新型船舶减排方法与传统船舶减排方法的比较，验证了SSSR方法的有效性。通过港口实际数据的一系列试验，验证了新的船舶减排方法的有效性。特别是在港口不同阶段，船舶排放可减少8.0%~11.9%，交通效率可提高3.8%~6.2%。
Ship emissions is one of the main components of port pollution. Inefficient waterway management may not only result in additional waiting time of ships, but also the aggravated emissions in port. With special consideration of combining scheduling optimization and speed reduction of ships in port, this paper proposed a new emission reduction method, called ship scheduling with speed reduction (SSSR). Performance of the SSSR method has been testified through comparisons between the new and traditional ship emission reduction methods based on the navigation safety under three different strategies. The effectiveness of the new ship emission reduction method has been testified through a series of experiments with practical data in port. Especially, under various stages in port, the emissions of ships can be reduced by 8.0%–11.9% and the traffic efficiency can be improved by 3.8%–6.2%.
