Abstract
The Revised Parallel DEVS (RPDEVS) modeling formalism enhances the Parallel Discrete Event System Specification (PDEVS) by the ability to model ’real’ Mealy behavior of components. The term ’real’ Mealy behavior can be summarized as immediate output response to an input event without a state transition in between. Although this enhancement simpli1es model creation, especially of reusable components, it requires a more complex simulation algorithm. In this paper, we present an RPDEVS abstract simulator that describes the simulation execution of RPDEVS models.
