Abstract The purpose of this study was to derive a set of sampling plans
to be used by the Western Wood Products Association for the reinspection of shipped lumber. Reinspection of a shipment of lumber
occurs when a claim of grade is made by the buyer.
Each sampling plan is derived in such a way so that its operating
characteristic curve would pass through two preassigned points.
These two points reflect the risks involved in sampling.
The Hypergeometric Probability Distribution was used to derive
the sampling plans when the lot size was 100 units. The Binomial
Probability Distribution was used to derive the sampling plans when
the lot size was 2,000 units. The Poisson Probability Distribution
was used to derive the sampling plans when the lot size was at least
5,000 units.
The sampling plans derived in this study are acceptance
plans to be used in attribute inspection.
