Abstract
The regular pattern of ship's operation is mined by processing massive AIS data records. Typical volume and distribution characteristics of the emission from ships in port are calculated through distributed computing. An Anylogic-based simulation model is built to find optimum berth schedule in terms of minimum emissions from ships in port. The findings are as follows: the main pollutants emitted from ships, SOx and NOx, change in similar way and mostly are concentrated at berthing area and main channel. Correlation analysis shows that the emission volume of exhaust gas is positively correlated with ship's activity level. The pollution level at berthing area is dependent on number of ships calling and their working hours.
