Digital Twins
A digital twin is truly a manufacturing future technology. A one-to-one replica of your factory, with all its production lines and areas laid out.
It can be useful in multiple ways, firstly for accurate tracking of the shop floor, and secondly, for conducting simulations of various changes you might want to make to your factory, so that when you implement the changes, you can have 100% confidence in the outcome. For example, you could simulate how moving one production line to another place would impact your productivity.
