摘要
本文以神经网络理论为基础,针对林产工业中板式家具生产过程的关键部分-如何组织最优化的下料方式来达到节省原材料,提高生产效益的问题,构建其数学模型,并运用遗传算法对神经网络进行权值优化训练,从而加速了神经网络的权值优化速度,克服了网络易陷入局部极值的困扰,实现了运用神经网络解决二维下料的一类问题。
     本文针对板式家具提出了下料优化算法,并对算法进行了软件设计,从用户界面到排料的效果图都体现了以人为本的重要思想。该研究可以使板式家具企业降低生产成本,缩短排料时间,从而提高企业竞争力。
     该算法的研究为相关下料行业,如:机械、建筑、钢铁、船舶、车辆、玻璃、造纸、皮革等制造业,提供了解决思路。
This project focus on the problem about how to optimize the usage of board material in the furniture industry. This paper first introduced the Genetic Algorithms and Artificial Neural Networks, which have been widely used in optimization of allocating. Then presented a method which using the genetic algorithms to optimize the weights of artificial neural networks, last applied the new method to optimize board allocating of furniture of production and present a test. The experiment result proofed that the method by using the GA for optimizing the weighs of the ANN can raise the utilizing rate of board and can shorten the time of the design. At the same time, this method can simultaneously search in many directions, thus greatly increasing the probability of finding a global optimum.
