基于Niche GA的灰色GM(1,1,λ,△t_k)优化模型

Optimized GM(1, 1, λ, △tk)Based on Niche GA

在非等间隔GM(1,1,D,△t_k)模型基础上,建立了更具一般性的非等间隔GM(1,1,λ,△t_k)模型,并给出了求解最优GM(1,1,λ,△t_k)模型的小生境遗传算法,实例证明,用GM(1,1,λ,△t_k)模型进行预测能取得好的效果。

On the basis of GM( 1, 1, D, λtk), a more general GM( 1, 1, λ, △tk) is developed. In order to find the optimized GM(1, 1, λ, △tk), a method based on Niche GA is given. An example proves that a good forecasting result using GM(1, 1, λ, △tk)model can be obtained.
