摘 要: 研究了灰色预测模型的优化问题,通过将正弦函数变换与新陈代谢思想结合得到了一种新的灰色预测模型的优化方法,并且将方法运用到我国客运量的预测模型中,通过比较发现方法的预测精度更高. In this paper, the optimization problem of gray forecaSting model is studied, A new method of the gray prediction model is proposed by combining the sine function transformation and the metabolism, and this method is applied to the prediction model of passenger volume in China, The comparison shows that the method has higher prediction accuracy.
