There is an entire industry built up concerining the plant foor manufacturing execution system, and it may seem like a complex thing, but in actuality it is not. Plant floor manufacturing execution systems are systems that execute manufacturing processes on the plant floor. Think automation and robotics.

This type of manufacuring system is common, and in fact absolutely vital,in many manufacturing plants in modern times because it not only allows for greater safety for the human workers present, but it also allows a much higher consistency of quality across products and makes for a much faster production system over all.
