Home Page of Inspection and Quality Control

The fundamental question of industrial quality-control is this. A production process generates a stream of items. There is a warranted concern that some of these items will be defective. What is the economically optimal strategy for separating defective from conforming items?

We are still working on this web-site and plan to add lots of extras soon. Do let us know what you think and any suggestions for stuff to include.
