Several solutions have been introduced to find an optimum trajectory for ship, such as Game Theory, Genetic or Evolutionary Algorithms and so on. However, ship's maneuverability should be taken into consideration before their real applications. This paper focuses on ship's trajectory control problem in anti-collision maneuvering. At first, a simple linear ship maneuverability model is introduced to simulate its movement under different speed and rudder angle. After that, ship's trajectory control is studied by considering the duration of rudder, operation distance to turning points, and maximum angular velocity. The details for algorithm design are also introduced. By giving some restrictions according to the requirements from COLREGs, the intervals for rudder angle in different circumstances can be determined by the curves. The results can give very meaningful guidance for seafarers when making decisions.}, doi = {10.12716/1001.07.01.11}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Game Theory, Anti-Collision, Colregs, Ship's Trajectory, Evolutionary Algorithms, Route Optimization, Anti-Collision Maneuvering, Genetic Algorithm (GA)} }
