摘要
以灰色理论GM(1,1)模型为基础,通过灰色技术的改进来预测生活需水量,对所建模型进行误差检验,并比较了改进后的预测模型和未改进的预测模型在精度上的差别,证明了改进后的预测模型具有可行性和较高的精度,在此基础上对连云港市的生活需水量进行了预测。
Basing on gray theory GM(1,1) model,through the gray technical improvement to raise the accuracy of GM(1,1) model,predicts the amount of life demanding water quantity,carries on an error margin examination,and compares the difference on the accuracy of improved model and ex-model.This article proves that the improved model has possibility and accuracy higher,and carries on an estimate about the needed amount of life demanding water in this foundation.
