灰色模型在城市环境噪声预测中的应用

Application of grey model on predicting the noise of urban environment

根据灰色系统理论 ,对太原市环境噪声序列分析表明 ,该序列是一非单调摆动序列或有饱和的S形序列 ,建立了相应的Verhulst灰色预测模型。结果表明该模型预测精度较高 ,最大残差小于0 .54%

According to the Grey System theory,the array of noise is analyzed. The array is not monotonous. We build the Grey Model—Verhulst Model to predict the noise of urban environment,the precision of the forecasting model is obvious.
