基于MATLAB的改进BP神经网络在城市日用水量预测中的应用

Forecast of Daily Water Demand of Urban Water-Distribution System Using Improved BP ANN Based on MATLAB

利用MATLAB神经网络工具箱对城市短期用水量进行模拟,比较各种改进BP神经网络对城市短期用水预测方面的效果,得出用BP神经网络预测城市日需用水量是可行的,其中尤以traincgp方法预测效果最好的结论.

Simulation of short term forecast for urban water consumption was carried out making use of MATLAB NNTool.After comparing the simulating effects of several improved BP ANN on short term forecast for urban water consumption,a conclusion that it was feasible to forecast short term urban water consumption using BP ANN can be draw,of which the simulating effect of traincgp method was the best.
