摘要
针对多船会遇态势下的船舶避碰决策难题,提出一种基于拟态物理学优化算法的船舶转向避碰决策方法。该算法将《国际海上避碰规则》相关条款作为约束条件限定问题的可行域空间,同时考虑基于最近会遇距离和航程损失的船舶避碰目标函数,通过迭代进化获取全局范围内的最优解。仿真结果表明:将拟态物理学优化算法应用于船舶转向避碰决策中是可行、有效的,能为船舶驾驶员提供决策支持。
The Artificial Physics Optimization （APO） algorithm with the feasible space constrained by The Rules from In- ternational Regulations for Preventing Collisions at Sea is introduced into the collision avoidance decision-making in multi- ship encounter situations. The objective function is constructed on the basis of the Distance of the Closest Point of Approach （DCPA） and the voyage losses, and solved through iterative evolution to obtain the optimal solution. The simulation of the process shows that APO algorithm works effectively in determining the course alteration for avoiding collision, therefore, can help marine officers in navigation practice.
