The paper concerns the acceptance sampling plans when the remainder of rejected lots is inspected. Two types of AOQL plans are considered – for inspection by variables and for inspection by variables and attributes (all items from the sample are inspected by variables, the remainder of rejected lots is inspected by attributes). These plans are compared with the corresponding Dodge–Romig AOQL plans for inspection by attributes. An algorithm allowing the calculation of these plans (with the use of software Mathematica) was presented. From the results of numerical investigations it follows that under the same protection of consumer the AOQL plans for inspection by variables are in many situations more economical than the corresponding Dodge–Romig attribute sampling plans.
