When building simulation models, the objective is to, as closely as possible, mimic the real-world environment. This becomes especially important as digital twinning increasingly becomes a business imperative and the benefits of analysis become more immediate and tangible.  The model discussed in this paper was developed as a concept of capability demonstration, addressing several open points raised by an existing factory simulation effort.   During several discussions concerning the modeling of Automated Mobile Robots, a concept of prioritized central dispatching control for the AMR’s was developed.  And on that basis, the simulation of information transaction flows much as one would simulate the movement of objects in the model.  As with Value Stream Mapping (VSM) information flows are as important as material flows in the model.  Finally, as a point of interest, a method is demonstrated here for modeling of AMR battery state of charge and recharging based on distance traveled and drive motor effort.
