    Abstract: A Shewhart R control chart is developed to monitor the process variance for large production runs. It is not appropriate to monitor the process variance using the Shewhart R control chart for short production runs. In this paper, we propose the design of the R control chart for short production runs. For various combinations of the number of samples and the size of each sample, control coefficients of the R control chart are calculated by numerical methods. Using these results, the R control chart for short production runs is developed to monitor the process variance correctly. Finally, the design procedure of the R control chart for short production runs and the results of misusing the Shewhart R control chart are illustrated by an example.
