Research on general weighted averages method of equipment material demands forecasting

On the basis of equipment material demands forecasting by establishing gray GM(1,1) model and BP neural net model, this paper builds up the mathematics model General Weighted Averages Forecasting Method that can impend over the real consumption. The new method can conquer the defect of simply using statistics analysis, gray system theory and neural net theory. It can also fully utilize the information offered by the model, and can gain more accurate forecasting results.
