改进的GM(1,1)模型及其应用分析

GIM(1)Model Comparison and Analysis with GM(1,1) Model

GIM(1)模型是一种改进的GM(1,1)模型。文章在介绍两种模型的基础上,分别进行实例计算和分析,得出了GIM(1)具有更大的优越性,具有预测结果精确,对时间的依赖性较小的特点。

GIM(1) regard as a kind of amended GM(1,1) model. Introducing two kinds of models, this article calculate through the example and analysis. It gets more accuracy conclusion and less apply time using GIM(1) calculation.
