Petri Nets are a graphical tool for modeling systems with concurrent processes. They include places, transitions, tokens, and arcs to represent system states and events. Extensions like Coloured Petri Nets (CPNs) and Stochastic Petri Nets (SPNs) allow for advanced modeling of complex systems with attributes and probabilistic timing. Generalised Stochastic Petri Nets (GSPNs) and Fuzzy Petri Nets (FPNs) offer nuanced analysis for systems with mixed behaviors and imprecision, respectively.

Petri Nets are a formal modeling language invented by Carl Adam Petri in the 1960s, widely used in various fields such as computer science, systems engineering, and operations research
Places, Transitions, Tokens, and Arcs
Petri Nets consist of places, transitions, tokens, and arcs, which represent conditions, events, states, and the flow of tokens within a system
Petri Nets are used for the analysis and design of complex systems in various fields, such as workflow management, communication protocols, manufacturing processes, and software engineering
CPNs allow for the differentiation between different types of tokens within a model by assigning them additional information or "colours"
SPNs incorporate probabilistic timing into transitions, making them useful for modeling systems with random events or uncertain timing
GSPNs combine immediate and timed transitions to model systems with a mix of deterministic and probabilistic behaviors, such as computer networks or manufacturing systems
FPNs integrate fuzzy logic into the Petri Net framework, allowing for the modeling of systems with imprecise or uncertain concepts
Petri Nets are used to visualize and analyze the dynamics of processes, identifying inefficiencies and improving process design
Petri Nets are employed in network analysis to assess performance metrics and optimize network configurations
Petri Nets are instrumental in verifying that systems adhere to requirements and perform reliably under various conditions, aiding in system design
Through simulation, Petri Nets enable the exploration of different scenarios and the discovery of optimal solutions for various systems
