In order to study the relationship between the ship domain and its influence factors, firstly, the changes of ship domain with different factors were statistically analyzed. Secondly, the changes nature of the ship domain with its influence factors were analyzed, and by using wavelet transform, the change rule of the sample data of ship field was studied. Finally, the modeling of correlation was conducted by using artificial neural network (ANN). In modeling process, the 2/3 data of wavelet transform was chosen for the training, and the simulating ability and robustness of the model were verified by the rest of 1/3 data. The average value of ship domain under every influence factors and the model of relationship between ship domain and its influence factors based on the artificial neural network were obtained. Results show that the model of ship domain has a good performance with a fitting degree of R 0.92242, and an average error 49.8970 m, and a better robust.
