Stochastic Petri Net Simulation [PDF]

open access: gold1989 Winter Simulation Conference Proceedings, 1989
Petri nets are a formal modelling tool very well suited to the description of distributed and concurrent systems which exhibit synchronization and contention for shared resources. Adding random temporal specifications to Petri nets, stochastic Petri nets are obtained from which event driven simulators can be automatically constructed.
