Construction of Chain Sampling Plan -1 Indexed Through Convex Combination of AOQL and MAAOQ

In Chain Sampling Plan, the sampling inspection has the criteria for acceptance and non-acceptance of the lot depends in part on the results of the inspection of immediately preceding lot. Chain sampling plans allows significant reduction in sample size under conditions of a continuing succession of lots from a stable supplier. In this paper a procedure for constructing a Chain Sampling Plan-1(ChSp-1) indexed through a parameter which is a convex combination of AOQL (Average Outgoing Quality Limit) and MAAOQ (Maximum Allowable Average Outgoing Quality) with gain parameter λ is given. This plan may safeguard the interests of both producer as well as consumer by properly choosing a right combination using the gain parameterλ. Tables are also constructed for the easy selection of the plan.
