PETRI NET

Domain	Definition
Computing	Petri net A directed, bipartite graph in which nodes are either "places" (represented by circles) or "transitions" (represented by rectangles), invented by Carl Adam Petri. A Petri net is marked by placing "tokens" on places. When all the places with arcs to a transition (its input places) have a token, the transition "fires", removing a token from each input place and adding a token to each place pointed to by the transition (its output places). Petri nets are used to model concurrent systems, particularly network protocols. Variants on the basic idea include the coloured Petri Net, Time Petri Net, Timed Petri Net, Stochastic Petri Net, and Predicate Transition Net.

Specialty Definition: Petri net

A Petri net is a mathematical representation of discrete parallel systems. They were defined in the 1960s by Carl Adam Petri. Because of their ability to express concurrent events, Petri nets are a generalization of automata theory.

A petri net consists of places, transitions and directed arcs. Arcs connect a place to a transition and vice versa. There can be no arc between two places or between two transitions. Places may contain any number of tokens. Transitions fire, that is consume tokens from input positions and produce tokens in output positions. A transition is enabled if there are tokens in every input position.

In its most basic form, tokens in a Petri net are indistinguishable from each other. More complex Petri nets add token coloring, activation time and hierarchy to the network.
