Abstract

In the realization process of multi-ship collision avoidance path planning, it is the foundation for decision-making of collision avoidance opportunity and behavior to accurately and rapidly determine the key collision avoidance target ship and the sequence for the ship to avoid collision with various target ships. Therefore, this paper introduces grey relational decision-making to comprehensively analyze, evaluates and selects key collision avoidance ship on the basis of risk degree evaluation parameters including distance to closest point of approaching (DCPA), time to closest point of approaching (TCPA), ship speed rate (K), and safe distance of approach (SDA) in multi-ship collision avoidance decision-making. Finally, the influence of various risk degree evaluation parameters on collision risk degree is analyzed through simulation, and an interactive interface of target ship collision risk degree ranking is established, to verify feasibility and superiority of this method.
