Invariant-Based Performance Analysis of Timed Petri Net Models

In timed Petri nets, temporal properties are associated with transitions as transition firing times (or occurrence times). For net models which can be decomposed into a family of place invariants, performance analysis can be conveniently performed on the basis of its components. The paper presents an approach to finding place invariants of net models and proposes an incremental method which, for large models, can significantly reduce the required amount of computations.
