D. Lai, K. Govindaraju, M. Bebbington] Using a counter example, we show that the formula for computing the Average Run Lengths (ARL) of a moving average control chart (MA) in Wetherill and Brown (1991) is incorrect. However, we conjecture that the formula may provide an upper bound for the ARL of a moving average control chart. © Heldermann Verlag Moving Average Control Chart nationallicence ARL nationallicence Zhang Lingyun Institute of Information Sciences and Technology, Massey University, Palmerston North, New Zealand aut Lai C.
