PDE Simulation
I designed and developed in a small team a parallel discrete event simulation (PDES) for supply chains. We developed a simulation model generator and a scalable, distributed simulator to generate and simulate huge supply chains e.g. over a period of 5 years with 30 billion products produced per year. It is a follow up project of the Arena simulation.
The simulator is described in more detail in this paper.

This figure shows the high level architecture of the simulator.
