Construction of Dependent Mixed Sampling Plans Using Single Sampling Plan as Attribute Plan

Independent mixed plans maintain stochastic independence between the probabilities of the variables and attributes constituents of the procedure. Dependent mixed plans are those in which the probabilities of the variables and attributes constituents of the procedure are made dependent. One of the advantages of the dependent mixed sampling plan is that it provides the optimal procedure in terms of the size of average sample number (ASN) associated with the plan. This paper presents the procedure for constructing the dependent mixed sampling plan using single sampling plan as attribute plan by taking AQL as a quality standard. This plan is compared with the independent mixed sampling plan indexed through AQL. Tables are constructed for easy selection of the plan.
