| 摘 要： | 为了解决多船避碰决策过程中避让行动优先级问题,提出一种基于模糊集合理论的船舶碰撞危险度确定模型。选取最近会遇距离、最近会遇时间、船间距离、相对方位、船速比5个因素建立碰撞危险度影响因素集,并确定各因素评价集、评价指标以及各参数的隶属度函数,经模糊综合评价得到船舶碰撞危险度计算模型。设置两船交叉会遇以及多船交叉会遇2种会遇局面进行仿真实验,实验结果验证了该模型的有效性。

| Abstract: | In order to solve the priority problem of ship avoidance actions in the process of multi-ship collision avoidance decision-making, a model for determining ship collision risk index based on fuzzy set theory is proposed. Select the distance of the closest point of approach, time to the closest point of approach, distance, relative bearing, and ship speed ratio to establish a set of impact risk factors, and determine the evaluation set of each factor, the evaluation index and the membership function of each parameter, and calculation model of ship collision risk index obtained by fuzzy comprehensive evaluation. Simulation experiments were carried out by setting up two-ship crossing situation and multi-ship crossing situation, the experimental results verified the validity of the model. |
