A New Approach of Background Value-Building and Its Application Based on Data Interpolation and Newton-Cores Formula
基于插值和Newton-Cores公式的GM(1,1)模型的背景值构造新方法与应用

In this paper, the author analyses that the building approach method of background value in grey model GM(1,1) is an important and that rationally constructing background value can improves precision and adaptability of the grey model. The method of background value reconstruction in grey model GM(1,1) based on data interpolation and Newton-Cores formula of numerical value integral is pointed out. Simulation examples show the effectiveness of the proposed approach.
