Very broad question but related: this blog [0] discusses how a modelling product was used to simulate the internet backbone. If your aim is real-time reaction modelling of actors, this could theoretically be implemented using such a system. They have an open beta [1], although building a comprehensive system like that described above seems a very significant task even to a large engineering team.
