Abstract
First, the factors which influence forecasting precision of GM(1,1) model is analyzed and it is considered that there is some error between accumulated sequence and discrete solution, which has effect on the precision of general model GM(1,1), then amelioration approach of GM (1, 1) forecasting model is proposed. Finally, the method of amelioration GM (1, 1) model is applied in modeling of chemistry fiber output and the results show the effectiveness.
