Application of Gray Forecast Model in Rapeseed Output Forecast

XU Fei(Fundamentals Department,Xijing University,Xi'an,Shaanxi 710123)  
Nicety rapeseed output forecast has vital guidance value for rapeseed crop area.By introducing the buffer operator to deal with the data's disturbance,a rapeseed output forecast model is built based on improved GM(1,1) model.Finally,through the example calculation,it is found that the improved GM(1,1) model could precisely predict the rapeseed output.
