Adding time to the Petri net provides the Petri net modeler with another powerful tool with which to study the performance of computer systems. Time can be associated with transitions, with selection of paths, with waiting in places, with inhibitors, and with any other component of the Petri net.
Timed Petri nets are used to detect and correct a possible livelock situation in the functioning of a protocol. This protocol is the reset procedure of the layer-three data transfer phase of the digital multiplexed interface (DMI) specification designed by AT&T. This data-transfer phase
Petri nets are a simple model of computation with a range of modelling applications that include chemical reaction networks, manufacturing processes, and See the network theory series here on Azimuth for a panoramic and well-diagrammed introduction to the theory and applications of Petri nets.

P-time Petri Nets have been recognized as powerful modeling and analysis tools for railway transport systems. Temporal disturbances in these systems include railway infrastructure, traffic management, and disturbances (weather, obstacles on the tracks, malice, social movement, etc.).
Timed Petri nets have been applied in the study of concurrent systems to determine the computation rate (or equivalently the cycle time) which describes the number of rings of a transition per unit time as the modeling system is operating at its maximum rate. Listed below is a review of results regarding the
This paper deals with modelling of traffic networks (TNs) for control purposes. A modular framework based on coloured timed Petri nets (CTPNs) is proposed to model the dynamics of signalized TN systems: places represent link cells and crossing sections
Distributed Model: Petri Nets Introduc4on • Introduced by Carl Adam Petri in 1962. • A diagramma4c tool to model concurrency and synchroniza4on in distributed systems. Example: EFTPOS FSA (Electronic Fund Transfer Point of Sale) Initial 1 digit d1 1 digit d2 1 digit d3 1 digit d4 OK OK OK OK
It then uses Deterministic Timed Petri nets to model the mobility event and evaluate the performance under different scheduling schemes. This model also helps to validate optimization methodologies that could lead to a set of design principles for any new mobility protocol as well as evaluate its Petri Nets is a well known approach in many application areas, but has not until recently got a high status within the field of system reliability. A generalized SPN (GSPN) allows timed as well as immidiate transitions, but only exponentially distributed firing times are accepted for pUF pDF pSF.

In this note controlled timed Petri nets are used as a model for hybrid systems. Control is implemented by delaying some of the transitions. The goal is to synthesize a control law such that the state never reaches a set of forbidden states. We discuss the problem of extending known
