Abstract In order to solve the problem of fixed weighting of the entropy weighting method, two models are proposed: a weight assignment method based on IOWGA operator and a variable weight combinatorial model based on entropy weighting and IOWGA operator. In this method, the prediction precision of each model is used as the induced value, and the single model is orderly weighted according to the magnitude of each period. We use an example to illustrate this method. Experimental results show that the method has the advantages of reasonable weighting process, better model higher prediction accuracy, and is more suitable for deformation analysis and prediction.
