灰色分离建模方法的改进

Improvement on Separated Modeling of Grey Model

结合灰色GM(1,1)模型的3种改进方法:平滑原始序列、分离建模、灰色Gompertz模型,提出一种改进的灰色分离建模方法。通过实例和对比分析,证明新的方法能够提高预测精度。

This paper studies improved methods of the grey GM（1,1） model,including smoothing original sequence, separated modeling and Gompertz model. Based on this, separated modeling of grey model is improved, and a more efficient fusion function is given. Using examples and comparative analysis, we illustrate that the new method can improve the prediction of precision.
