摘要
提出了用线性自回归AR(p)模型和自回归滑动平均模型ARMA(p,q)模拟面粉厂电力消耗的成本,分析了电力成本的价格构成,给出了模型建构方法,并说明了模型在中短期预测中的应用。
This paper advances simulating the cost analysis of power consumption in flour mills with the linear autoregression model AR(p) and the autoregression running means model ARMA(p,q), analyzes the price formation of the power consumption cost, provides the method for establishing the models, and discusses the application of the models in medium and short cost forecasting.
