On the transient response of open queueing networks using ad hoc distributed simulations

Ad hoc distributed simulation, a methodology for embedded online simulation, has been studied for the steady-state simulation of open queueing networks. However, for most online simulation applications, the capability of a simulation approach to respond to system dynamics is at least as important as the performance in steady-state analysis. Hence, this paper focuses on the prediction accuracy of the ad hoc approach in open queueing networks with short-term system-state transients. We empirically demonstrate that, with slight modification to the prior ad hoc approach for steady-state studies, system dynamics can be modeled appropriately. Furthermore, a potential livelock issue that arises with the modification is addressed.
