| 摘 要： | 针对灰色模型在建筑物变形预报中存在的问题,提出了改进灰色模型的要求。该模型运用了距离最近影响最大的原则,对建模数据赋以一定的权,以体现各个数据的重要性不同;同时给出了三种不同的加权方法;最后,结合工程实际,比较了经典灰色模型和加权改进灰色模型的预报效果。结果表明本文的方法能很好地改善预报精度。

| Abstract: | According to the problems of prediction gray model(GM) deformation,the weighted GM is put forward.This model uses the principle of the shortest distance for the maximum influence to give the modeling data certain weights.At the mean time three different ways to determine weight is given.Finally,an example from engineering practice is discussed to compare the classic GM and weighted GM,and the results show that this method can improve prediction accuracy. |
