An optimal attribute control chart has been derived in two stages. Initially the conditions for the fictitious specification limit of compressed-limit gauging acceptance sampling plans to obtain a minimum sample size have been adapted to control charts. Using these requirements for minimum sample size, the sample size, the frequency of sampling, and the extent of the control limits from the fictitious process average have been determined, assuring the minimum expected total cost incurred in utilizing narrow-limit gauging fraction-defective control charts for controlling current production.
