Application of statistical methods and artificial neral networks for approximating ships roll in beam waves

In the paper, were presented approximations of numerical calculations of ships roll on thebasis of main service parameters of the ship. This way were obtained several relationshipswhich make it possible to approximate ship roll in regular and irregular waves by usingthe parameters available in the phase of voyage routing. The relationships were elabora-ted by means of artificial neural networks as well as linear and non-linear regressionmethods. A comparative analysis of the methods regarding approximation accuracyagainst standard data was also performed
