摘　　要：为解决船舶避碰决策中对碰撞危险度计算精度不足和对危险目标船辨识性差的问题,使用基于Coldwell船舶领域的危险识别参数改进多船避碰危险度评估模型,比较改进前后模型的精度。使用VC++实现船舶MMG运动模型,对基于改进模型的四船交叉会遇态势作避碰决策仿真。仿真结果表明:对同一危险船,改进模型的精度更高;在多船会遇中,改进模型能够识别运动参数相似的危险目标船,辨识性更高。改进模型可为更复杂的多船避碰决策提供理论支持。In order to solve the problems of insufficient accuracy of collision risk calculation and poor identification of dangerous target ships in ship collision avoidance decision-making,the multi-ship collision avoidance risk valuation model is improved using risk identification parameters based on the Coldwell ship domain,and the accuracy of the models before and after improvement is compared.VC++is used to implement the ship MMG motion model,and the collision avoidance decision-making simulation on the four-ship crossing encounter situation based on the improved model is carried out.The simulation results show that:the improved model is of higher accuracy for the same dangerous ship;in multi-ship encounters,the improved model can identify dangerous target ships with similar motion parameters,which is of high identification.The improved model can provide theoretical support for more complex multi-ship collision avoidance decisions.
