| Abstract: | 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. |
