Chaotic Characters and Forecasting of Urban Water Consumption
Hongwei Zhang · China Water & Wastewater · 2008
The chaotic characters of time series of urban water consumption were judged using the chaos theory.A short-term forecasting model on urban water consumption and a multi-step forecasting approach were put forward based on the largest Lyapunov exponent.The example research shows that the forecasted result is better than that based on the artificial neural network.The forecasting precision is higher within maximum predictable time scale than that beyond of it.
