弱化改进后的灰色预测模型研究

Research on the gray forecasting model after weakening improvement

以武广客运专线某路段工程实测数据为基础,先用灰色理论进行建模预测,再用弱化改进后的灰色模型进行建模预测,并分别与实测数据进行对比,结果表明,弱化改进后的灰色预测模型预测精度会有很大的提高,能够满足工程要求,从而最大限度的减少观测期数而大大的缩短工期。

Taking the project practical measuring data of one stage on the Wu-Guang passenger dedicated line as base,it firstly utilizes the gray theory to get model establishment and prediction,then gets model establishment and prediction utilizing the gray model after weakening and improved,and compares them respectively.Results prove that the forecasting model of the gray forecasting model after weakening improvement has large improvement,can satisfiy project requirements,thus decreasing measurement period number a...
