Synthetic Prediction Method for Industrial Water Demand

The prediction of industrial water demand is one of the important parts for the management of water resources. In this paper, a formula for synthetic universal prediction is developed by the synthesis of merits of the tendency method, the block prediction method, the correlation method, and the utilization rate raising method of repeated utilization by different trades. The formula, with the characteristics of simple structure and universality, reveals theoretically the internal relations between the conventional prediction methods, and with it the universal software is easy to be programmed. An effective method is also provided for water demand prediction for complicated industrial systems involving various departments and trades in water resources management of large regions. Practical application shows that the formula can improve the flexibility and efficiency of scheme analysis by integration of supply demand analysis and the optimization configuration model.
