反向累加生成与灰色GOM(1,1)模型的优化

Grey opposite-direction accumulated generating and optimization of GOM(1,1) model

相对传统累加生成,分析了反向累加生成,并结合反向累加生成的特点,改进了传统GOM(1,1)模型背景值的计算方法,给出了灰色GOM(1,1)模型参数求解的优化方法.具体算例的计算表明,这种方法能够提高GOM(1,1)模型的预测精度,验证了该方法的有效性与实用性.

Compared to traditional accumulated generating, analysis the opposite-direction accumulated generating, and with the characteristics of opposite-direction accumulated generating, improve the calculation method of background value of traditional GOM（1,1） model, one optimized method of parameter solution of GOM（1,1） model is presented in this paper. Examples show that the method in this paper can improve the prediction precision of the GOM（1,1） model, so the effectiveness and practicability of this method is proved.
