Research on grey forecasting model of multi-factor time series

Considering the deficieney of the pracrical use of traditional forecasting me thod of single-factor time series,a grey forecasting method model for a mudti-factor time series is established by using DGM(1,1)model hased on the principle of multi-element linear regression to sgnthesige the various factors.The paper firstly forecasts the factors that affect the developing trend by using DGM(1,1)model,and further predicts the general development trend by using the method of multi-element linear regression and synthesizing the various factors.Finally,by forecasting and analysing the employment in Shaanxi province,the model is checked,obfaining some better results.
