Abstract :
Based on the characteristics of the grey system theory modeling, this paper presents a new modeling method - accumulating method, of system parameter identification for GM(1,1) model. The comparison example is designed to show that the forecasting precision of the GM(1,1) model is improved and the calculating volume is decreased greatly, by means of the accumulating method. Finally, the parameter relationships and properties of the new model are discussed.
