The optimal produce coefficient of the background value is put forward and the computation formula has been derived by the authors based on the shortages of the computation method of the background value in the GM(1,1) model-grey prediction model, the weighted grey prediction model-PGM(1,1) model has been constructed, the computation of the optimal produce coefficient of the background value and the grey parameters have been discussed using the iterative computation methodology in detail, the results of the practice examples show that the PGM(1,1) model is superior to GM(1,1) in the fitting accuracy and the prediction effect.
