• short production;
  • probability of getting a signal;
  • average run length for signal;
  • truncated average run length;
  • average number of false alarms

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.
