Advanced research on the ameliorating GM(1,1) model

In this paper, the precision and adaptability of the grey GM(1,1) model is analyzed in details and improved by initial value setting adjustment. The selection of initial value has an important effect on the GM(1,1) model's precision. So, this paper deals with the GM improvement in modification of initial value, and obtains great improvement in forecasting precision. Finally we validate the practicability and reliability of the models with numerical examples.
