Such systems do not enjoy a product form solution, thus their analysis is typically carried out through approximate mean value analysis (AMVA) techniques. We formalise the problem in PEPA in a way amenable to differential analysis. Experimental results show that our approach is competitive with simulation and AMVA methods. date: 2010-09 pagerange: 1-6 event_title: 9th Workshop on Process Algebra and Stochastically Timed Activities (PASTA) event_location: London, UK event_dates: September 2010 event_type: workshop refereed: FALSE citation: Casale, Giuliano and Tribastone, Mirco Process-algebraic modelling of priority queueing networks.
