摘要
通过将灰色预测GM(1,1)模型和马尔可夫预测方法相结合,建立了一种对GM(1,1)模型修正的Markov-Grey模型,并利用原始数据对2007年至2010年中国用水总量进行预测。从预测结果分析可以看出,经过Markov-Grey模型对GM(1,1)模型修正后,预测精度有明显提高。
Through combining Markov prediction method with GM(1,1) forecasting model,it establishes a Markov-Grey model mixed with revised the GM(1,1)model.Then it uses the history data to predict 2008 to 2010 total Chinese water consumption.Based on analysis of the forecast results,it shows that the forecast precision by this model has greatly improved.
