construction of group acceptance sampling plan using weighted binomial distribution

Acceptance sampling plans developed relating to groups of items on testers is called the group acceptance sampling plan (GASP). In this scheme, a sample of items is distributed into different groups and a lot of product is rejected if more than a specified number of failures are recorded in any group. A group acceptance sampling schedule can be used to save the time and cost in inspection as compared with classical acceptance sampling. In this paper, a procedure for constructing a group acceptance sampling plan (GASP) using weighted binomial distribution in the construction of sampling plan is proposed. Suitable tables and examples are also provided for easy selection of the plans.
