Industrial Water Requirement Forecast Model and Application Based on PCA-BP Neutral Network

ndustrial water requirement is usually influenced by multiple factors, among which have close relations, which can cause distortion of some forecasting results, and weaken the suitability of some formulas. To this end, we adopt BP neural network model, use principal component analysis (PCA) to analyze the relationships between variables of the model to solve the related issues between the various factors, in order to set up forecast model of industrial water requirement and take Zhengzhou City as an example to analyze. The results showed that this method could take the influenced factors of industrial water requirement into consideration comprehensively, offer higher and more accurate forecasts, and provide the reference framework for integrated planning of regional water resources and long-term water supply planning.
