摘要
在传统灰色系统理论建模分析的基础上,将原始观测数据序列与所建模型预测数列进行比较,并将比较后的残差纳入系统,继续建立灰色模型进行分析。事实证明:在建筑物变形分析中使用残差灰色组合模型,能有效提高模型精度,获得良好的预测效果,是一种既方便又可靠的变形分析方法。
This paper analyzes the traditional model of gray system theory,based on the original observation data sequence and the model predicted the number of columns compared with the residual and more into the system after,continue to build the gray system model for analysis.Facts have proved： Using the residual gray combination model in the building distortion analysis,can improve effectively the accuracy of model,obtain good prediction,is a convenient and reliable method of deformation analysis.
