You have 3 automatic testing machines(ATEs) to test produced devices and 1 operator. There are 3 steps to each ATE, 2minutes to hook up, 7 minutes to test and 2 minutes to unhook. A total of 11 minutes each.
You can run each ATE simultaneously (staggered start and finish) and send the tested product for packing and shipping.
At maximum operator speed how long will it take each device to come off the test line?
How many devices can you test completely in a 1 hour shift?
How many can you test completely in an 8 hour shift with a 30 minute luch break?
