In this paper, we study one‐sided control charts based on precedence statistics. Because we focus on the problem of detecting ‘smaller’ lifetime than expected, we consider only one‐sided control charts that have not received much attention in the literature. Alarm rate and average run length are derived when the process is in control and also when the process is out of control for two Lehmann alternatives. On the basis of the alarm rate and …
