为研究初始条件对新陈代谢GM(1,1)模型预测效果的影响,该文建立了四种基于不同初始条件的新陈代谢灰色模型,通过对比分析该四种模型在三种不同变形演化规律的工程实例中的预测结果,得出在上述四种初始条件中,基于n∑t=1[x~((1))(k)-x~((1))(k)]~2=min的新陈代谢灰色模型可以在短期内对沉降监测做出更加准确的预测。
In order to study the effect of initial conditions on the prediction of metabolic GM (1,1) model, four metabolic gray models based on different initial conditions were established in this paper. By comparing and analyzing the results of three different models of deformation and evolution, In the above four initial conditions, we conclude that the metabolism based on nΣt = 1 [x ~ ((1)) (k) -x ~ ((1)) (k)] ~ 2 = min The gray model can make more accurate prediction of settlement monitoring in a short period of time.
