Automotive processes simulated by an ODE - PDE model

Abstract
This paper presents some simulation results for a supply chain, that describes the different construction phases of car engines. In particular, the supply chain is modeled using differential equations the load evolution is given, inside each arc, by a conservation law with constant processing rate; the dynamics at a node is solved considering ordinary differential equations for queues, that model the exceeding parts. For simulations, some numerical schemes based on Upwind and explicit Euler methods are proposed and compared with alternative approaches, which use different time and space meshes and data structures. This last alternative allows to obtain high computational gains, with consequent advantages in terms of industrial processes simulations.
