摘要
本文讨论了GM(1,1)预测模型存在的一些问题,提出了评价原数据序列指数变化规律性的方法,并在此基础上对GM(1,1)预测模型建模方法作了一定的改进,在一定程度上提高了预测精度,改进后的GM(1,1)预测模型更合理、适用性更强。
Some problems o(?) the grey forecasting model are discussed in this paper, and a meshod to evaluate the exponential regularity of the original discrete data series is proposed, and then, an improvement on grey forecasting model is conducted, Anatytic experience shows that the improved CM (1,1) model is more acurate and more rational.
