新陈代谢模型滑动指标检验及其在道路交通噪声预测中的应用

Moving Index Test of Metabolism Model and its Application in the Road Traffic Noise Prediction

定义了灰色新陈代谢模型的滑动指标,实现了对新陈代谢模型各项精度指标及其稳定性的动态检验。对长春市1995年～2006年城市道路交通干线噪声监测的数据运用灰色系统理论,分别建立了3种预测模型,并对这3种模型的各项滑动指标、一步预测滚动指标分别进行了检验。

Moving index test of Metabolism Grey Model was defined in order to give the model dynamic test of precision and stability. Via the traffic noise monitoring data from 1995 to 2006 of Changchun,three prediction models were made,include metabolism GM(1,1),metabolism DGM and metabolism VERHULST. Based on the analysis of the moving index test and one step prediction test,it shows that metabolism GM(1,1)and metabolism VERHULST model can be used due to their better prediction and stability. Both of the two models ...
