当过程均值和标准差不恒定时,监测变异系数是统计过程控制的成功方法之一。为了进一步提高Castagliola等人(2011)提出的指数加权移动平均(EWMA)控制图的灵敏度,提出了一种改进的EWMA控制图。提供了新图表统计特性的表格。一些数值结果和比较表明,新的图表有一个平均运行长度性能上级其他竞争程序。一个来自制造业的真实的数据实例表明,它在应用中表现相当不错。
Monitoring coefficient of variation is one of the successful approaches to Statistical Process Control (SPC) when the process mean and standard deviation are not constants. This paper presents a modified Exponentially Weighted Moving Average (EWMA) chart in order to further enhance the sensitivity of the EWMA control chart proposed by Castagliola et al. (2011). Tables are provided for the statistical properties of the new chart. Some numerical results and comparisons are given and show that the new chart has an average run length performance that is superior to some other competing procedures. A real data example from manufacturing shows that it performs quite well in applications.
