Credit in acceptance sampling on attributes

Credit is introduced in acceptance sampling on attributes and a credit-based acceptance sampling system is developed that is very easy to apply in practice. The credit of a producer is defined as the total number of items accepted since the last rejection. In my sampling system, the sample size for a lot depends via a simple function on the lot size. the credit. and the chosen guaranteed upper limit on the outgoing quality and will be much smaller than in isolated lot inspection. My credit-based acceptance sampling system also yields a simple continuous sampling plan.
