Probability of Lot Acceptance for Two-Sided Chain Sampling Strategy based on Exponential Distribution
This article suggests two-sided chain sampling strategy for exponential distribution. The proposed plan has two acceptance criteria, where the first criterion is the lot is accepted when the current lot contains no nonconforming units. For the second criterion, the lot is accepted when there is one nonconforming unit found provided that the cumulative number of nonconforming units from the preceding and succeeding lots is at most one. Otherwise, the lot is rejected. For the proposed plan, the performance is measured based on the probability of lot acceptance, P_a (p), where it is calculated at various values of mean ratio. The proposed plan eventually will provide an alternative plan for the industrial practitioners to choose from for the inspection of a product.
