摘　　要：在AIS信息环境的基础上,利用模糊数学的评判理论,把影响船舶碰撞危险度的主要因素DCPA、TCPA、会遇两船间的距离、目标船方位、目标船舷角、会遇两船的航速比以及各影响因素的权值等作为评判船舶碰撞危险度的参数,模糊量化各因素对碰撞危险度的影响,从而比较合理准确地确定船舶间的碰撞危险度.In AIS information environment,the parameters of main factor affecting the risk degrees of vessel collision,such as DCPA,TCPA,the distance of the meeting vessels,the bearing and relative bearing of the target vessel,speed ratio of the meeting vessels,value of the factors affecting the risk degrees of vessel collision,etc.are analyzed.The paper introduced a method in estimating the affecting degrees of the above-mentioned factors to risk degrees of vessel collisions by applying the estimating theory of fuzzy mathematics,and thereby the risk degrees of vessel collision are reasonably determined.
