Data stream prediction model based on weighted moving average 基于加权移动平均(WMA)的数据流预测模型
Exponentially weighted moving average model 指数加权移动平均(WMA)数模型
In this paper, combining today's more popular data mining techniques, using linear regression and the weighted moving average algorithm, sales were predicted. 本文结合当今比较流行的数据挖掘技术,分别利用线性回归和加权一次移动平均算法对销售量进行了预测。
This paper studies that the bullwhip effect of order releases and the amplifications of safety stock arise within the supply chain even when the demand model is ARIMA ( 0, 1, 1 ) and the forecast method used is a simple exponentially weighted moving average. 研究了发生在供应链中订货的牛鞭效应和安全库存放大问题,其需求模型是ARIMA(0,1,1),而所用的预测方法是简单的指数平滑。
A stochastic model of the random early detection ( RED ) queue length and its exponentially weighted moving average ( EWMA ) value is developed based on stochastic analysis. 运用随机分析的方法建立了一个关于RED(randomearlydetection)队列长度及其指数加权滑动平均值(exponentiallyweightedmovingaverage,EWMA)的随机模型。
