A variable sampling interval EWMA t chart with auxiliary information – A robustness study in the presence of estimation error
This article proposes the variable sampling interval (VSI) exponentially weighted moving average (EWMA) t chart for the process mean using auxiliary information (AI) (denoted as the VSI EWMA t-AI chart). The proposed chart allows different sampling intervals to be adopted based on prior process qual...
