摘要
由于非等间隔GM(1,1)灰色模型对于处理数据量小且表达信息不确定的数据具有优越性,因此广泛应用于石油天然气勘探、机床故障诊断、电力负荷预测、大坝安全监测等领域。基于非等间隔GM(1,1)灰色模型理论,利用某小区建筑物沉降观测的实测数据,建立了适合该小区建筑物沉降预测的灰色模型。通过对比理论预测值和实测值,并进行模型对应的精度评定分析,结果表明,此模型适用于该建筑物沉降预测分析的研究。
Due to unequal interval GM （ 1,1 ） gray model for dealing with a small amount of data and uncertain data demonstrated su- periority, it is widely used in oil and gas exploration, machine fault diagnosis, power load forecasting, dam safety monitoring fields. In this paper, the theoretical basis of unequal interval GM （ 1,1 ） gray model, use one building settlement observation point measured data, a gray model for settlement prediction of the residential building. By comparing the theoretical value and the measured value, and the corresponding analysis and model accuracy assessment. The results show that this model is applicable to the building settlement predictive analysis.
