摘要:
A computer program is presented that may be used to develop specific sequential variables sampling plans. The program was motivated by the following problem situation. A producer is required to make the following statement about a lot,“With 100γpercent confidence, at least 100P percent of the items in the lot are within specifications.”Although this statement is in terms of a tolerance interval, in effect, it comprises an acceptance sampling plan, since failure to meet the criterion results in rejection of the lot. Since sample sizes are not specified in advance, it may be tempting for the producer to begin with a few items, and then to take additional samples if the criterion is not met. This sequential approach, of course, increases the consumer's risk from an acceptance sampling plan viewpoint. A plan is developed that permits the sequential approach but keeps the consumer's risk at a desired level.
