SYSTEM AND METHOD FOR INSPECTION OF PRODUCTS WITH WARRANTIES

摘要

A batch of units (12-1 to 12-N) of a product are inspected by inspection system (10) before they are supplied to customers with warranties. The units (12-1 to 12-N) 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 (12-1 to 12-N) identified as being defective are repaired. A dynamic inspection technique has been developed and can be used to identify different thresholds for which numbers of units within a batch (12-1 to 12-N) need to be inspected, such that costs due to the inspection, repair and warranty are minimized.
