一、引言 上世纪80年代以来神经网络的理论、应用、实现及开发工具的发展速度加快,这主要得益于计算机科学和人工智能的发展,也为人工神经网络应用到各个领域并发挥实质性作用提供了技术上的可能性.
Currently,the use of artifiacial neural network in society economy has become the most challenging and absorbing hotspot. In this study, we used the BP network and the toolboxes of the matlab 6.5 to construct prediction and warning system on the time serial datum which is based on the models of population, resource, environment and economy developing in harmony and the coefficients of developing in line after the evaluation of the in-phase-development degree of population, resource, environment and economy.
