Research on the decision system of the ships evade bump based on the AIS

Automatic Identification System(AIS) is a way to transntificatifer large amount of information, overcoming barriers, resistance to weather influences, with ship shore, boat shipping information networking capacity and close global automatic identification system of the target display. Research directions only for the vast expanse of ship collision avoidance decision-making, but based on the mathematical model for ship collision risk of AIS information environment set up and the proposal of ship collision avoidance decision, present and even future intelligent automatic collision avoidance system for ships in the maritime sector a comprehensive research and development bring great practical value.
