在本文中，我们提供了一个自适应的第二阶段非参数指数加权移动平均控制图使用可变的采样间隔检测范围内的位置参数的变化。该图是一种自适应图，具有可变的采样间隔，这使得它更有效。此外，它是一种自启动方案，因此可用于在启动阶段监控过程。图参数的选择进行了研究，和模拟研究表明，所提出的控制图不仅执行不同的分布鲁棒性，但也有效地检测各种幅度的变化。最后，以一个实例说明此控制图的应用。版权所有© 2014约翰威利父子有限公司.
In this paper, we provide an adaptive Phase II nonparametric exponentially weighed moving average control chart using variable sampling interval for detecting a range of shifts in the location parameter. This chart is an adaptive one and has a variable sampling interval, which makes it more efficient. Further, it is a self‐starting scheme and thus can be used to monitor processes at the start‐up stages. The choice of the chart parameters is studied, and a simulation study demonstrates that the proposed control chart not only performs robustly for different distributions, but also efficiently detects various magnitudes of shifts. An illustrative example is given to introduce the implementation of this proposed control chart. Copyright © 2014 John Wiley & Sons, Ltd.
