The authors consider a closed multiclass queuing network model in which each class receives a different priority level and jobs with lower priority are served only if there are no higher-priority jobs in the queue. Such systems do not enjoy a product form solution, thus their analysis is typically carried out through Approximate Mean Value Analysis (AMVA) techniques. They formalize the problem in PEPA in a way amenable to differential analysis. Experimental results show that their approach is competitive with simulation and AMVA methods.
