Abstract
In this manuscript, three repetitive types of sampling plans using the generalized process capability index of multiple characteristics are presented, which include a repetitive sampling plan, a resubmitted sampling plan and a multiple dependent state repetitive sampling plan. The plan parameters of these sampling schemes are determined through the nonlinear optimization solution. The comparison among these proposed plans is made in terms of the average sample number required. The use of the proposed plans is given with the help of an industrial example.
