This paper is focused on continuum-discrete models for supply\udchains. In particular, we consider the model introduced in [10], where a system\udof conservation laws describe the evolution of the supply chain status on\udsub-chains, while at some nodes solutions are determined by Riemann solvers.\udFixing the rule of flux maximization, two new Riemann Solvers are defined. We\udstudy the equilibria of the resulting dynamics, moreover some numerical experiments\udon sample supply chains are reported. We provide also a comparison,\udboth of equilibria and experiments, with the model of [15]
