Inspection and Detection
I am getting ready to release some kit to production but need to come up with an inspection routine for this.
Inline monitoring is not a possibility so I need to tag QC onto the end of the process. The machine will output 3000 units an hour and due to the size of the staff the maximum inspection rate will be 1/250. The machine has a problem that causes it to occasionally produce ~10% defective units. The distribution of these defects are random throughout the finished units.
How do I use these figures to calculate the average amount of time to detect this issue or even if we are likely to detect it at all?
Obviously if I can show that employing an extra person to increase our inspection rate will save money overall then I can get this person.
Thanks in advance for you help.
