Modeling Research on Non-equidistance GM( 1,1 ) Model
非等间距GM(1 ,1) 模型建模研究

In this paper, based on the exponential trait of grey model and the definition of integral, the reconstruction method of GM(1,1) model's background value of non-equildistance sequence is put forward. The background value reconstructed by using this method is by far more precise. Moreover, GM(1,1) model's fitting precision and prediction precision is advanced and the scope of application is enlarged.
