Multiclass queueing networks have been used to model manufacturing and communication systems. For those multiclass networks with a static priority service discipline, the diffusion approximation for the queue length of a higher priority group is identically zero. This approximation is not satisfactory, particularly when the traffic contributed by those higher priority class customers in each station is not negligible. The goal of this project is to propose better approximate methods for analyzing multiclass networks, especially those with feedback structure.
