自律型群行動モデルによる海上交通流の再現 : モデルの提案と行動特性の検討

抄録

This paper deals with a marine traffic simulation that uses a new concept model. A new autonomous ship cluster behavior model is proposed that utilizes parallel distributed processing. The model has three basic concepts: (1) Ships are regarded as multi agents that have sensors, intelligent decision-making processes and effecters ; (2) Marine traffic is regarded as a complex system ; (3) Decision-making for ship operation is determined based on several forces that act on a given ship. The compositional force is calculated from a goal attainment force, a centripetal force, a collision avoidance force and a following force. Forty-nine cases were simulated that varied in terms of weight of the centripetal force and weight of the collision avoidance force. The process of ship cluster development, collisions in the cluster and its geometrical shape are discussed.
