By simulating the supply chain system under step demand, the effectiveness of the resilience enhanced control method of container logistics supply chain is verified. The results show that the method of the present invention significantly weakens the output response oscillation of the container logistics supply chain system, reduces the response time and enhances the system resilience.

摘要： The present invention proposes a vessel traffic pattern identification method via data quality control and data compression. Firstly, assort a collection of Automatic Identification system (AIS) data points according to Mobile Service Identify (MMSI) code and sort each collection result by time ascending order, and then delete duplicated vessel AIS data points considering time stamp, latitude, longitude and vessel speed over ground, then segment vessel trajectories. Secondly obtain high-quality AIS data with an AIS data anomaly detection and repair and compress each vessel trajectory with the Douglas-Peucker algorithm. Thirdly, cluster vessel trajectories with the Quick Bundles algorithm, and identify maritime traffic pattern.
