Symbolic Analysis of Timed Petri Nets

Abstract

In timed Petri nets temporal properties are associated with transitions as transition firing times (or occurrence times). Specific properties of timed nets, such as boundedness or absence of deadlocks, can depend upon temporal properties and sometimes even a small change of these properties has a significant effect on the net’s behavior (e.g., a bounded net becomes unbounded or vice versa). The objective of symbolic analysis of timed nets is to provide information about the net’s behavior which is independent of specific temporal properties, i.e., which describes preperties of the whole class of timed nets with the same structure.
