Abstract :
An optimization method base on Genetic Algorithms is used to calculate the control capability of the dynamic positioning system of a ship. Real number coding is used as the code of Genetic Algorithms, and the sum of ratio which the real force of five propellers occupy each maximum force at a given wind velocity is considered as the fitness function, and roulette wheel selection is chosen as the selection methods to ensure the capability calculation Genetic Algorithms has convergence. The results of calculation show that this method owns the same accuracy as the normal capability calculation, and less time is used in the calculation process.
