基于分形理论的需水量预测方法

Water Demand Forecasting Method Based on Fractional Theory

在研究有关分形理论的基础上 ,提出了基于分形拼贴定理和分形插值函数迭代生成过程的需水量预测新方法 .该方法根据分形拼贴定理 ,求取一个与历史记录相近的吸引子的迭代函数系统来求取分形插值函数 ;通过分形插值函数的迭代生成 ,建立预测模型 .并以实例证实该方法的合理性及可靠性 .

Based on the introduction of fractional theory, a new method of forecasting water demand is presented in this paper. It uses the iterated function system whose attractor is close to the historical data to establish the fractional function, and according to the iterative process of fractional function to set the forecasting model. The example shows the mehod is rational and reliable.
