The technique is often used to eliminate seasonal components is from data, for which a 12-month moving average would be needed . 这种技术经常被用来消除季节因素,对此,需要12个月的移动平均数。
Centred 12 - month moving average 十二个月定位移动平均数
The use of the six - year moving average almost inevitably means that , in any particular year , the investment return of the investment portfolio will be higher or lower than the calculated fee rate 年移动平均数,几乎无可避免地意味在任何一年,投资组合的投资回报会高于或低于计算所得的费用。
Comparing these two tables we can see that the error terms give us a measure of how good the forecasting methods ( two or three month moving average ) would have been had we used them to forecast one period ( month ) ahead on the historical data that we have 比较这两张表,我们可以看出,误差使我们度量出好的预测方法(二个或三个月移动平均数)会是有我们使用他们展望一个期间(月)向前在我们有的历史数据。
Using the order - up - to ( out ) method and two demand forecasting patterns , that are exponential smoothing forecasting and moving average forecasting , we give the frequency response plot and the noise bandwidth figure with the help of the system control tool of matlab . we show that information sharing helps to reduce the bullwhip effect , especially at higher levels in the chain . however , the bullwhip effect problem is not completely eliminated and it still increases as one moves up the chain 本文的重点内容就是用控制论的理论和方法来研究牛鞭效应,应用补充到目标库存策略( out )和两种不同的需求预测方法,即指数平衡预测法和移动平均数预测法,用matlab的系统控制工具箱作为分析工具,分别给出了信息共享情况下和无信息共享情况下的频率响应图和带宽比较图,证明了信息共享能够减弱牛鞭效应,尤其是在供应链的高级阶段,但牛鞭效应并不能完全消除,仍旧随着供应链阶段的上升而增加。
