The Evaluation of H 106 Continuous Sampling Plans under the Assumption of Worst Conditions

Dodge-type continuous sampling plans are used to screen mass produced items so that long run quality requirements will be met. The choice of a particular Dodge-type plan is often based on the plan's aoql, the long run proportion of defectives that remains in the output after inspection under the assumption that the production process is in a "state of statistical control." Another measure by which a plan can be evaluated is the uaoql, the long run proportion of defectives remaining under the assumption that the production process operates in the worst possible way relative to the plan. This paper presents five graphs that can be used to provide uaoql values for a large number of h 106 plans. The linear program used to calculate these graphs is also included.
