Abstract
A batch of units of a product are inspected before they are supplied to customers with warranties. The units are either defective or non-defective, realizing a defect index which is a random variable characterized by a statistical distribution. During the inspection, the units identified as being defective are repaired. A dynamic inspection technique has been developed and can be used to identify different thresholds for which number of units within a batch need to be inspected, such that costs due to the inspection, repair and warranty are minimized.
