改进蚁群算法的舰船避碰辅助决策系统可靠性研究

Reliability design of ship collision avoidance auxiliary decision system based on improved ant colony algorithm

传统舰船避碰辅助决策系统所采用的蚁群算法在对船舶路径碰撞信息素计算过程中,存在收敛速度慢、碰撞信息素浓度低的问题,导致输出结果的可靠性较低,因此提出改进蚁群算法的舰船避碰辅助决策系统可靠性设计方法。通过对船舶避碰路径模型的构建与分析,结合传统蚁群算法在避碰决策计算上的缺失数据,对蚁群算法进行改进,并将改进的蚁群算法引入到避碰辅助决策系统进行仿真计算,通过对决策数据的分析得到舰船避碰辅助决策可靠性数据。通过设计仿真实验对得到的可靠性数据进行验证,证明了本文方法所得数据的可靠性。

In the process of calculating collision pheromone of ship path collision,the ant colony algorithm used in the traditional ship path collision pheromone system has some problems,such as slow convergence speed and low concentration of collision pheromone,resulting in low reliability of the output result.Through the construction and analysis of ship collision avoidance path model,combined with the traditional ant colony algorithm in computing collision avoidance decisionmaking of missing data,to improve the ant colony algorithm,and the improved ant colony algorithm is introduced into the collision avoidance decision-making system for the simulation calculation,based on the analysis of ship collision avoidance decision-making data aided decision reliability data.The reliability data obtained by the simulation experiment is verified,and the reliability of the data obtained by the method in this paper is proved.
