Abstract A forecasting software titled GMRCFS has been developed based on the GM(1,1) residual error model of grey system, and deformation of Geheyan dam has been predicted by five GPS monitoring sites on June 10 to November 28 in 1998. The results show that the GM(1,1) residual error model has high accuracy, it could satisfy the demand of dam deformation forecasting if a step size is chozen reasonably.
Key words :
grey system
GM(1,1) model
