Multi-Level Variable Sampling in the Variable Mode

The problem of determining the optimal falsification and inspection strategies for a two-level verification system in which false alarms are possible is investigated. A solution in the form of an optimal statistical test procedure and optimal falsification strategy is presented for a special case in which one of the items to be verified is measured with a more accurate device, the others with a less accurate one. The solution is shown to be valid for sufficiently small combined falsifications of the data.
