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。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 itis an useful method for prediction. The authors also compiled a micro - computer program which deals with process of grey prediction.
