摘要
介绍了GM(1,1)灰色模型的建模过程,应用等维递补方法对其进行修正,得到等维灰数递补模型,采用该模型对2010–2020年浙江省总人口进行了动态预测.精度检验结果表明,模型预测精度较高、预测结果可靠.
The process of modeling GM(1,1) gray model was introduced in this paper.After being fixed by the method of recursive compensation of identical dimensions,the model could be developed into GM(1,1) model with recursive compensation by grey number of identical dimensions.Then,dynamic forecast of the population of Zhejiang Province in the period 2010 to 2020 was hold by using the newly obtained model.Accurate comparison result shows that the forecasting is more accurate and the result is more reliable.
