In this paper we consider the superposition of independent Coxian arrival streams. We propose a method to efficiently approximate the superposition process, based on state space aggregation. The method is applied to a single server queue and to an inventory control model. Simulation results show that the method accurately estimates performance characteristics and that it significantly outperforms two-moment approximations.
