摘要
介绍了灰理论及GM模型的建模方法,结合我国2000-2005年居民生活电力消费,建立了GM(1,1)预测模型.通过对模型精度及预测值精度的检验,认为该模型具有较高可信度,适用于居民生活电力消费的预测.
This paper introduces the grey theory and the modeling method of GM, and sets up GM（1,1） forecasting model on the basis of electricity consumption of daily life from 2000 to 2005. By analysizing the precision of the model and predicted valuc, the results show that the model has high reliability and can be used for the forecast of electricity consumption of daily life.
