This paper introduced the Genetic Algorithms (GAs) and Artificial Neural Networks (ANNs), which have been widely used in optimization of allocating. The combination way of the two optimizing algorithms was used in board allocating of furniture production. In the experiment, the rectangular flake board of 3650 mm×1850 mm was used as raw material to allocate 100 sets of Table Bucked. The utilizing rate of the pcard reached 94.14% and the calculating time was only 35 s. The experiment result proofed that the method by using the GA for optimizing the weights of the ANN can raise the utilizing rate of the board and can shorten the time of the desing. At the same time, this method can simultaneously searched in many directions, thus greatly increasing the probability of finding a global optimum.
