Add to ORKGThis paper presents a numerical tool for the simulation of supply chains based on two different fluid dynamic models. One is based on a mixed continuum-discrete model, it means that the load dynamics are solved in a continuous way on the arcs, and at the nodes imposing the conservation of the goods density, but not of the processing rate. In fact, each arch is modelled by a system of two equations: a conservation law for the goods density, and an evolution equation for the productive capacity. According to the other model, the load dynamics are described by a conservation law, with constant processing rate, inside each supply subchain, and an entering queue for exceeding parts. The dynamics at a node are solved considering an o...
