a = Pr{exceeding contro] limits | process in control}
p = Pr{exceeding control limits | process out of control}
ARL1 = average run length while in control
= Ma when the measured statistics are independent ARL2 = average run length while out of control
= Mp when the measured statistics are independent ATS = average time to signal an expected shift
= h!p when the measured statistics are independent ECL = expected length of a Ä…uality cycle
