Neritic mooring system simulation based on simulated annealing

TAN Fenglin;XU Haicheng;SHEN Zimin;TANG Xilin;School of Mathematics,South China University of Technology;  
According to the marine environment features of the mooring system which is the transport node of the neritic observation network,the quasi-Newton iteration algorithm is used to calculate the inclination of barrel and tube,mass of weight ball,draft and nomadic range of buoy under different wind speeds and water depths. In view of the convergence of calculation,the simulated annealing is adopted to determine an elegant solution as an initial value. Addition of the parameter which linearly decreases with simulated annealing temperature and controls updating amplitude is proposed. The searched solutions are accepted with a certain probability during the large range search. Then the small range search is carried out around the found elegant solutions. The simulated mooring line chain shapes under different conditions shows that the change trend of line chain shapes complies with the influence trend of conditions like wind speed and force,and the improved simulation annealing method has practicality.
