The concept and the classification of forecasting are addressed. Aiming at the disadvantages of the current forecasting models, such as requirement for more data and narrow application extent, an improved GM(1,1)-transfer function-noise model for forecasting is proposed. In the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted so as to fulfil the forecasting by only using a few of data.

For the lack of return data in the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted, and forecasting is carried out by only using a few data. When the data amount reaches 50, the hidden quantitative relationship between sale quantity and return quantity is established by performing the transfer function-noise model. Its parameters are determined through model identification, parameters estimation and diagnostic checking. Then, forecasting return is accomplished.
