本文用时间序列分析方法分析水泥生产过程,笔者假设水泥生产过程为一个平稳的随机过程,它的二十八天抗压强度为具有控制项的自回归模型。用30组数据建立了28天水泥抗压强度动态模型,并做了跟踪,分析了七天抗压强度、细度、SO_3等与二十八天抗压强度的关系。最后,把生产中实际值和预测值进行了比较。 This article uses time series analysis method to analyze the cement production process. The author assumes that the cement production process is a stable random process, and its 28-day compressive strength is an autoregressive model with control items. A dynamic model of cement compressive strength for 28 days was established using 30 sets of data, followed by tracking, and the relationship between compressive strength, fineness, SO 3, etc., and compressive strength for 28 days was analyzed. Finally, the actual and predicted values ​​in production are compared.
