摘要
本文分析了灰色系统理论GM(n,h)模型的建模机理,进而指出了用该模型来分析处理大坝安全监测数据序列存在的问题。在定义了中心累减生成、均值生成等基础上,导出了一种新的动态系统灰色模型──DGM(n,h)模型。算例分析表明:DGM(n,h)模型比GM(n,h)模型有明显的优越性。
This paper analyzed the mechanism of model establiehment of grey system theory GM(n, h) model.Then, it points out the existing problems for using that model to analyze and process large dam safety monitoring data array.On the basis of defining central accumulative reduction generation,equal value generation etc., it finds out a new dynamic system grey model桪GM(n,h) model.Analysis of typical calculation manifests that DGM(n, h)model possesses evident superiority than GM(n, h)model.
