中文摘要：提出一种基于细菌觅食算法的避碰航路优化算法.该算法优化避碰参数包括避让转向时机、安全避让角度、复航时间和复航角度,细菌状态空间对应解空间.利用最近会遇距离和到达最近会遇点的时间,迭代计算趋化、繁殖和迁移算子,从而获得最优解.通过模拟仿真对遇、追越和交叉3种会遇态势,该算法可有效优化避碰航路,给出最优的避碰参数.该算法可为船舶避碰决策提供新的方法和思路.

外文摘要：An algorithm for ship collision avoidance route optimi- zation based on bacteria foraging algorithm is proposed, which optimizes the collision avoidance parameters including time to al- teration, safety alteration degree, navigational restoration time and navigational restoration angle. Bacteria state space is corre- sponding to solution space. To obtain the optimal solution, the algorithm iteratively calculate reproduct, transfer operator using DCPA and TCPA. The effectiveness of the algorithm is verified by simulating three encounter situations including the head on head situation, over-taking situation, cross situation, which can optimize avoidance route, and give the optimal parameters. The study can offer new method and thought for collision avoidance decision.
