Coloured Petri nets

Coloured Petri nets are a mathematical modeling tool used to represent complex systems involving multiple components and data. They extend traditional Petri nets by allowing tokens (representing resources or information) to have different "colors" or types, enabling the modeling of diverse entities within a single framework. This makes them especially useful for understanding systems like communication networks, manufacturing processes, or software workflows, where different data types and interactions are involved. Essentially, they help visualize and analyze how various parts of a system work together, ensuring better design, performance, and reliability of complex systems.
