HE Xi-ping, HUA Xi-sheng, HE Xiu-feng. Weighted multi-point grey model and its application to high rock slope deformation forecast[J]. 2007, 28(6).DOI:
Slope deformation is a complex systematic process. Single point model named GM(1
1) can’t consider correlation of the deformation between the discrete monitoring points. The method of determining dynamic weight is presented; and the new weighted multi-point grey model named WM-GM(1
1) forecasting the slope deformation is established by analyzing the shortcoming of GM(1
1) which can’t acquire the appropriate background value. A case study based on the Matlab program shows that the forecast result of WM-GM(1
