I am looking for the most optimal receiving inspection plan, because the test is time consuming. Our vendor claims their outgoing reject rate is 0.03%. We receive batches of 900 pcs at a time. If I select AQL=0.25 (the defect is critical), per double sampling plan the sampling size in best case should be 50/100. Is there a way for me to lower the sampling size without increasing the AQL too much?
