| 摘 要： | 该文提出了稳健灰色模型,并将其应用于某建筑物沉降的预测。结果表明,稳健GM(1,1)模型比常规GM(1,1)模型具有更好的抗干扰性能和受异常点影响小的优点,更具有预测应用价值。同时还编写了计算机程序对灰色预测过程进行电脑处理,大大减少了工作量。

| Abstract: | The robust grey model GM(1,1) has been proposed and used to predict the subsidence tendency of building.The results show that as compared with normal GM(1,1) model,the robust GM(1,1) model has advantages of better resistence against disturbance and less deviation by influence of outliers,so it is an useful method for prediction.The authors also compiled a micro-computer program which deals with process of grey prediction. |
