The feeder-selector system for Station #3 in your synchronous 6-station assembly machine has just suffered catastrophic failure and is not repairable. Luckily, your company has another similar feeder-selector system in storage, but the control parameters need to be recalculated to properly set up the feeder. You know your assembly machine can make an average of 530 assemblies per hour and only breaks down once every 48 parts. When the machine is down, the feeder and other subsystems are down too, but usually, the error can be found and fixed within 2.25 minutes on average.
You also know the new feeder can deliver components in 4 possible orientations to the selector (with equal probability), but only one of these orientations can pass through the feed track to the assembly head. Parts that are not in the correct orientation will be rejected by the selector and then fed back into the feeder hopper.
To set your control parameters, determine how fast the feeder must deliver components to the selector so there is not a shortage at the assembly machine. (Desired final units: parts/min)
