Title: Rectifying LTPD sampling plans for combined inspection by variables and attributes
Authors: Jindrich Klufa - Prague University of Economics and Business (Czech Republic) [presenting]
Abstract: The acceptance sampling is studied. We shall consider the lot tolerance percent defective (denoted LTPD) sampling inspection plans when the remainder of a rejected lot is inspected, i.e. the rectifying LTPD plans. These plans were introduced by Dodge and Romig for inspection by attributes (each inspected item is classified as either good or defective). Similar rectifying plans for inspection by variables were introduced by the author of this contribution. We shall consider combined inspection in which all items from the sample are inspected by variables, but the remainder of a rejected lot is inspected only by attributes. We shall show that the combined inspection is optimal in many practical situations. Using the LTPD plans for combined inspection by variables and attributes, we can often achieve significant savings in the inspection cost under the same protection of producer and consumer.
