Petri nets were invented by Carl Adam Petri to model concurrent systems and the network protocols used with these systems. The Petri net is a directed bipartite graph with nodes representing either "places" (represented by circles) or "transitions" (represented by rectangles). 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).

Business processes can be represented as Petri Nets in the COSA Process Designer. This representation type is based on the rather mathematical Petri Net theory. Petri nets are represented as directed graphs. A directed graph consists of nodes that are connected by arrows (transitions that have a direction). During execution, a token moves from one state to another and controls the execution state. Business processes can also be designed as object-oriented business process diagrams.
A Petri net (also known as a place/transition net or P/T net) is one of several mathematical representations of discrete distributed systems. As a modeling language, it graphically depicts the structure of a distributed system as a directed bipartite graph with annotations. As such, a Petri net has place nodes, transition nodes, and directed arcs connecting places with transitions.
