Two risks are always attached with acceptance sampling schemes. Let producer’s risk be a and consumer’s risk be b. The producer requires that the lot acceptance probability should be larger than 1 a at AQL and the consumer wants the probability of acceptance should be less than b at LQL. The plan parameters will be determined such that the following two conditionsat points ( a, p
