The aim of this study is to develop and evaluate the application of artificial neural networks to forecast parameters of the Weibull distribution. We used data from permanent plots of eucalyptus, measured on eight occasions. We adjusted the Weibull function with two parameters for all plots and occasions, by the method of maximum likelihood. The projection of the diameter distribution was made through artificial neural networks. We compared the proposed method to the method traditionally used in modeling the diameter distribution. The models using ANN presented improvements in the graphic dispersion of the residues, as well as the evaluated statistics. The proposed method was superior to the commonly used method.
