Multi-layers and multi-objects fuzzy optimization model of main target ship;

This paper,employing math principals entroy,attempts to draw some laws and characteristics of uncertainty of anti-collision behavior in restricted visibility.

Discussion on collision avoidance actions against vessels on forward of port a beam;

Dynamic responds of a vehicle during collision avoidance were obtained through simulation.

In this paper,on the basis of discussion on conditions involving overtaking and on the responsibility of the overtaking vessel,the causes of the collision which happened frequently and the collision avoidance relationship of the vessels under converging overtaking/crossing situation are analyzed,and the cautions of the collision avoidance under this situation are proposed.

Analysis on Getting out of Line of Fisherman and Discussion on Dodge Measures of Merchantman;

On dualistic pattern Of"emergency & anti-collision" in traffic accident identificatio;

On the basis of the analysis on the heading course, the ratio of speed and the relative course, this paper holds out a math model about anti-collision action.
