Fuel consumption prediction model for sail-assisted ships based on hybrid kernel function ARS-SVR
In order to effectively predict the fuel consumption of ships, a ship fuel consumption prediction model based on a hybrid kernel function is proposed. The support vector regression (SVR) models of the radial basis function (RBF) and the polynomial single-kernel function are constructed respectively, and adaptive random search (ARS) algorithm is used to optimize them. On this basis, the ship fuel consumption prediction model based on the hybrid kernel function ARS-SVR is established. A sail-assisted very large crude carrier (VLCC) is used as the research object, and the ship fuel consumption prediction is carried out based on the real ship monitoring data. The results show that compared with the single RBF and the polynomial single-kernel ARS-SVR, the root mean square error of the prediction result by the model based on the hybrid kernel function ARS-SVR is reduced by 19.8% and 30.2%,respectively. The proposed ship fuel consumption prediction model can improve the accuracy of the calculation of the sail-assisted ship fuel consumption,and is helpful to optimize the energy efficiency of ships and improve the management technology.
