I'm not focusing on the about production rate at all, and I am in agreement with your conclusion on production rate, just to be clear.I think you are making it too complicated. If step 2 takes 10 minutes, you can only make a car every 10 minutes regardless of conveyor size. Once the line is full, the queue times do not impact production rate, unless the conveyor itself is the bottle neck (for example, can only move one assembly at a time, and it that takes more than 5 minutes).
The buffering does help with process synchronization (having material ready when the step is available). In your example, if you don't fill the buffer in the conveyor, each car has only a 20 minute build time. Less queue time, same build rate.
I'm trying to figure out the total time a car spend in the line, which is relevant to the discussion of delay between VIN registration and assignment. As you mentioned up thread that the line is bumper to bumper, and also thet they likely have buffering to help with process synchronization, then the situation should be close to what I depicted. And my conclusion is that any speed up in robot processing time will also help the queue time. Do we have any disagreement here?
