| Abstract: | Since the gray model(GM) has been proposed,gray prediction model has made great achievements in economic,disaster,deformation etc.But in fitting accuracy and prediction accuracy,GM has some problems.Based on the classic gray model,we summarized and discussed improved methods for establishment of GM for better fitting and prediction. |
