Weighted GM (1,1) model in deformation monitoring of applied research

摘要：

Based on the priority principle of new information in grey system theory, the new information counts much in information cognition to the old. As the traditional GM (1,1) model does not reflect the importance of the new information. In order to take full advantage of new information, weighted GM (1,1) model is applied to predict landslide deformation works, but also the weighted to make a preliminary discussion on the selection, from the predicted results and measured results of comparative analysis, the weighted cumulative generated by GM (1,1) model for simulation and prediction Accuracy than the traditional GM (1,1) model to simulate and predict with high precision, thereby shows its efficiency and Practicality.
