Markovian networks of finite capacity queues are widely used models for performance evaluation of systems and networks. Unfortunately, excepted in some specific situations, these models are not tractable analytically [2]. Approximation techniques, aggregation, fluidification have been proposed to capture the behavior such systems. But, in most complex cases, simulation remains the only tool to estimate the steady state of the system.
