The effect of shift distribution on the design and performance of the X and CUSUM charts in monitoring mean and variability

Yang, Mei; Wu, Zhang; Liu, Tien-I. - In: European Journal of Industrial Engineering 7 (2013) 2, pp. 224-247

When monitoring a variable x in statistical process control, it is necessary to monitor both the mean and variability. Recently, it is found that, if both the mean shift δμ and standard deviation shift δσ follow the uniform distribution, many control charts with different complicacy are...
