利用灰色模型预测年用水量

Use of Grey Model for Forecasting Annual Water Demand in J City

介绍了灰色预测模型理论及其建立的方法,并分析了这一方法在工程中的应用。针对我国东北地区J市历史供水数据少的特点,建立了年用水量灰色预测模型,通过编码使用MATLAB求解结果,经检验,预测结果精度高,模型有效可行。

The development of water supply system is in fact the development of applied mathematics in water supply system. This paper introduces GM theory and method of its establishment, making an application and analysis of this method in practical project. Aiming at the feature of lacking historical water supply data in J city of northeast area in our country, annual water demands GM was established, calculating results according to the use of MATLAB. It turns out that the forecast result is in high accuracy, and the model is feasible and effective.
