Petri-net

Petri-net

A model given by C.A. Petri in which there are interconnections of two kinds of nodes: node-places and node-transition. Transitions modeled by a rectangle are the actors ( where the computations are fired orinitiated). For firing transitions the tokens are from the node-places. A token is an input or flag or asynchronously occurring event.
