Preface of the International Workshop on Petri Net-based Security (WooPS)

In timed nets [65], [70], [83], firing times are associated with transitions, and transition firings are real–time events, i.e., tokens are removed from input places at the beginning

Fig.19 shows one of possible Petri net models for such a tool with a dual–blade robot; the double use of chamber 2 in each cycle is represented by two unload/load transitions (t 2a

In timed Petri nets temporal properties are associated with transitions as transition firing times (or occurrence times).. Specific prop- erties of timed nets, such as boundedness

Timed Petri nets have been introduced by Ramchandani [Ram74] by assigning firing times to the transitions of Petri nets (t–timed nets), and by Sifakis [Si77] by assigning time to

For this reason, the non-structural properties can be used as limiting conditions on the class of transition systems eligible for Petri net (pre-)synthesis; this will be

To verify the reachability of the previously given marking (h1 + 2 + 2i.Send), the backward reacha- bility analysis is performed using the inverse CPN, illustrated in Fig.8.. Those
