On the Performance of Two‐sided Control Charts for Short Production Runs

Abstract

In this paper, statistical performance measures for short‐run production are summarized and proposed. Evaluation and computation based on these performance measures were developed for the two‐sided Shewhart, cumulative sum, and exponentially weighted moving average control charts. Applying these measures, we provided numerical illustrations to compare the efficiency of the three charts and the corresponding Q charts in the cases of known and unknown nominal values of process parameters.
