An approach towards distributed simulation of timed Petri nets

The authors present a model of timed Petri nets which is more general than known models in terms of modeling convenience. The model consists of simple but fairly general modules. This results in simpler and more modular codes for simulation of these systems, as compared with the known models of timed Petri nets. Time can be associated with either a place or a transition or both. The model consists of several simple modules resulting in modular code for simulation. The authors present an approach towards distributed simulation of the model. The well-known distributed simulation schemes for discrete event systems do not directly apply to these systems due to the nonautonomous nature of place nodes in timed Petri nets. The authors incorporate several ideas in the proposed approach to increase the degree of concurrency and to reduce the number of overhead messages in distributed simulation.
