Abstract
The main intentions that we use sampling systems are ➀ to assure required quality to post-process and ➁ to make suppliers (pre-process) manufacture products of required quality, giving them information about the results of inspection. Sampling systems such as ISO 3951 [1], ISO 2859 [2], etc., specify the AQLs (Acceptable Quality Levels) which should be the upper limit of process average, as well as the switching rules which inform the suppliers about quality level in order to meet the required quality. KOYAMA [3] has, however, pointed out poor sensitivity to process changes, as a weak performance of these sampling systems with the switching rules.
