Distributed simulation of timed Petri nets: basic problems and their resolution

Presents 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 would result in simpler and more modular codes for simulation of these systems, as compared with the known models of timed Petri nets. After discussing this model, the authors present an approach towards its distributed simulation. The well known distributed simulation schemes for discrete event systems do not directly apply to these systems due to the non-autonomous nature of place nodes in timed Petri nets. Moreover, in the authors' approach they incorporate several ideas to increase the degree of concurrency and to reduce the number of overhead messages in distributed simulation.< >
