ON THE DEVELOPMENT OF ANTI-COLLISION SYSTEM AMONG SHIPS

本研究的主要目的是建立全体值班人员都能使用的防碰防搁浅作业标准。首先，利用船舶操纵模拟器进行了一系列的实验，以获得无地理限制海域船舶碰撞导航员的知识库。利用模糊推理理论对导航员主观风险水平进行建模，并通过一系列的仿真实验，获得导航员对航道地理限制下的主观风险水平的认识。这些知识库相结合，并在狭窄的海峡航行的仿真模型。通过一系列的航海模拟验证了在船舶之间、船舶与交通控制中心之间的沃茨拥挤和限制水域使用操作标准的有效性，并开发了在给定航道地质限制条件下的航线设置算法，以支持船长和引航员的工作量，并从船舶交通控制中心监控船舶航迹。通过与海上实测航线的比较，验证了该算法的有效性。该模型也适用于评估海上大型建筑工程对海上交通的影响。

The main purpose of this studies is to establish the operational standard for preventing ship's collision and stranding that all watch officers are usable. At the first, a series of experiment using a ship handling simulator was carried out to get the knowledge base of navigator of collision between ships at sea area without any geological restrictions. The subjective risk level of navigator were modeled by Fuzzy reasoning theory.Then anther series of the simulator experiments were done to get the knowledge of navigator on subjective risk level on geographical restriction of water way. These knowledge bases are combined and included in a simulation model for navigation at narrow straits. A series of the nautical simulation verified the effectiveness of usage of operational standard at congested and restricted waters among ships and between on board and traffic control center.The algorithm for setting the course line under given geological restrictions of water way were developed to support the work load of captains and pilots and monitoring the ship track from vessel traffic center. The model based on this algorithm were well verified comparing with the course lines observed at sea. This model were also applicable to assess the influence of marine traffic due to large scale construction work at sea.
