pGM(1,1)灰色预测模型及其应用

pGM(1,1)Grey Prediction Model and Its Application

分析了GM( 1,1)模型在背景值取值上的不足 ,提出了一种基于权的pGM ( 1,1)模型 ,并用该模型进行了实际的变形预测。

By analyzing the limits of GM(1,1) prediction model in gaining background value, A new pGM(1,1) model, which has advantage over GM(1,1) in prediction efficiency, is set up based on p-weigh in this paper, and applied to practical deformation predictoin.
