| 摘 要： | 建立以终点碳和温度为间距的氧气用量非等间距灰色数列预测模型,并利用广义回归神经网络对灰模预测结果进行非线性组合优化,得到氧气质量的综合预测值.通过采集到的某钢厂实际生产数据,建立氧气质量的组合预测模型,得到平均相对精度达到97.39％的一步预测值.验证结果表明该组合模型是准确而有效的.

| Abstract: | The non-equidistant grey sequence prediction model for the oxygen dosage was established,which takes terminal carbon and temperature as spacing and employs a generalized regression neural network to nonlinearly optimize grey prediction results so that acomprehensive prediction value of the oxygen dosage can be reached.Basing on the sampled data from a steel works,a combined prediction model for the oxygen weight was established to get a predicted value which boasting of 97.39% in average and relative accuracy.The verification results show that the combined model is effective and accurate. |
