非等间距GM（1，1）建模方法对比分析及应用

摘要

非等间距GM （1，1）模型为实际工程变形监测中不等间距观测数据的处理提供较好的解决途径。文中以两种非等间距GM （1，1）建模方法为研究对象，通过工程实例的对比分析与实际应用，讨论两种模型的建模差异，给出模型精度与预测评价，提出选择非等间距GM （1，1）建模方法的参考建议。%Non‐equidistant GM (1 ,1) modeling is an efficient solution to the non‐equidistant data process for the engineering deformation monitoring projects .This paper focuses on two different non‐equidistant GM (1 ,1) modeling methods and discuses their differences with real practical engineering applications .Both models’ precision and prediction evaluation are compared and the reference for non‐equidistant GM (1 ,1) modeling is given .
