An automobile factory planning system and method for controlling a cycle time. The system comprises a conveyor belt configured to transport a plurality of automobiles at a controlled displacement velocity along a manufacturing path through the automobile factory. A feedback device is configured to provide a visual indicator of a designated position at which a next automobile is to be placed on the conveyor belt relative to the position of a previous automobile. The designated position is calculated as a function of the cycle time and the displacement velocity of the conveyor belt.
