| 摘 要： | 在介绍灰色预测模型和一元线性回归模型的基础上,结合某煤矿实际,采用两种模型对瓦斯涌出量进行了预测,并对两种模型的预测值进行比较,结果表明:对基本符合线性关系的数据,采用灰色GM(1,1)模型较一元线性回归模型的预测精度要高。

| Abstract: | On the basis of introducing two kinds of basic forecasting methods of grey forecast and the forecast of one element linear regression,and in combination with the actual situation of coal mines,this paper predicted the amount of gas emission and compared the accuracy of forecast values of the two methods.The results show that,for the data conforming to the linear relationship,Model GM(1,1) of grey forecast is better than one element linear regression in accuracy of forecast value,and this provides the ways a... |
