In order to ensure that the delivered products meet the outgoing quality requirement, a quality control of lots produced is performed before they reach the final serviceable stock. There, a single acceptance sampling plan by attributes is used to guarantee an acceptable outgoing quality level. A sample of size n is drawn randomly from each lot produced and inspected item by item. If the number of defectives does not exceed the acceptance number c, then the lot is accepted. Otherwise, the lot is rejected, and a 100% inspection is performed in order to sort all the defective items. We assume that the defective items are not rectifiable. Hence, all the defectives, found either in sampling or in 100% inspection, are rejected with no replacement. Depending on the proportion of defective items found in each lot rejected compared to the threshold value r, the decision maker can decide whether or not to immediately initiate the overhaul.
