In which applications can we use Petri nets at intervals?

06 November 2018 0 7K Report

The appropriate model must therefore be able to express non-temporal constraints. Interval Petri nets are well suited for modeling quantitative constraints using the same concept of temporal constraint representation in a temporal RdP.
