the exponentially weighted moving average

It shows that the demand variability does not increase when the retailer relies on the simply exponentially weighted moving average or the simple moving average to forecast demand.

提出了当零售商采用一次平滑指数法或简单移动平均法获得需求信息的过程中，不存在波动放大现象。

Experiments show that wavelet filtering can enhance the small fault detection capacity and detect more timely compared with exponentially weighted moving average (EWMA) filter.

实验表明，小波滤波法能提高小故障的检测能力，而且与指数权重滑动平均滤波法相比更具有故障检测的及时性。

Then we use adaptive exponentially weighted moving average (AEWMA) control charts to control the process which satisfies the two-component model.

接下来就是进行过程监控方法的研究。本文主要对生产过程利用可适应性指数加权滑动平均(aewma)法进行质量控制。
