COST MINIMIZING SINGLE SAMPLING PLANS WITH AIQL AND AOQL CONSTRAINTS.

This paper investigates and formulates the relationships among average incoming quality limit (AIQL), production process quality level and average fraction defective after production process for a single-stage manufacturing connected-unit situation. Cost components of the system are identified. In order to derive minimum cost single sampling plans where inspection is by attribute, a mathematical model is developed and plans are obtained using discrete optimization for the total expected loss function subject to AIQL and AOQL equality constraints.
