| 摘 要： | 传统GM(1,1)模型是最基本的灰色预测模型,无偏GM(1,1)模型是在传统GM(1,1)模型基础上的一种改进,它消除了传统GM(1,1)模型本身所固有的偏差.对无偏GM(1,1)模型的动态行为特性进行分析,并与传统GM(1,1)模型进行对比,明确了无偏GM(1,1)模型特性和适用条件.

| Abstract: | Traditional GM(1,1) model is the base of grey forecasting model.Unbiased GM(1,1) model is an improved model based on traditional GM(1,1) model and it eliminates the inherent deviation of traditional GM(1,1) model.The dynamic feature of unbiased GM(1,1) model is analyzed;and the comparison between unbiased GM(1,1) model and traditional GM(1,1) model is given so as to clarify its model characteristics and suitable conditions. |

| Keywords: | unbiased GM(1 1) model convergence divergence chaos |
