New idea about realizing automatic collision avoidance on the sea

The rapid development of computer technology and widely application of artificial intelligent provide technology support for realizing navigation automation on the sea, which has achieved great success in shipping advanced countries like Japan, England, America, Germany and also in the developing country, China. However, it still remains in the studying period up to now in aspects of collision avoidance decision-making mathematical model and reasoning mechanism. In this paper, approaches are proposed to establish the collision avoidance automation system. One of them is based on the former studies to realize automation system by make use of finite state machine theory and following the International regulations for Preventing Collision at Sea, 1972. The others are to establish the new idea about automatic collision avoidance system by taking advantage of the free flight idea, hybrid system, game theory used in air traffic management studies in recent years and the common characteristics in both air and sea traffic management.
