Classification calculation on water consumption of urban water supply network based on clustering analysis

The rule of users´ water consumption variation plays an important role in the urban water supply network simulation model. It´s the main basis of calculating node flow, and has great influence on the accuracy of the network model and the reliability of the optimization scheduling. Because of the complexity of the variation of water in the urban water supply network simulation modeling process, put forward the clustering analysis to the user according to the actual water consumption data, and reasonable classification method to every kind of users, find out the rule of the typical users´ water consumption variation. It lay a solid foundation for the node flow prediction and the accuracy of modeling.
