摘要
本文提出一种等维灰数递补动态预测技术。通过对所获信息的不断有效利用,将灰色动态GM(1,1)模型中灰参数逐次加以修正,使模型不断得到改进,从而提高了预测精度。应用实例表明,用本预测技术可取得较满意的结果。
A technique of dynamic forecasting with recursive compensation by grey numbers of identical dimensions is proposed. The grey parameters in a GM(1,1)-model can be successively modified here by efficient utilization of informations. This is an improvement on the simplified GM(1,1) so that the accuracy of forecasting model can be increased by the said means. Application shows that this forecasting technique is capable of giving satisfactory results.
