摘要
对GM(1,1)模型原始数列进行对数变换,减缓了数据变化的趋势,并通过matlab编程实现模型计算,简化了模型计算。将模型应用于胶州湾前湾海域水质预测,结果表明,模型对于单调数列的预测精度较高,预测结果与实测值吻合较好。
This article logarithmically transforms the original data serial to slow down changes in trend. In this article the model is carried out by Matlab in order to simplify the calculating. We apply the improved modle to the water quality forecasting of Qian Wan sea area of Jiao Zhou Bay. The results indicate that the forecasting precision of the improved model is better for monotonically increasing data serial, and the forecasting results fit well with measured values.
