Abstract: The usual way to handle larger problems is to divide them into subproblems. Traditionally this is a weak point in Petri nets. Introduction of hierarchies in the net is one solution to the problem. An alternative way to decompose Petri nets is to model every subproblem as an independent net. These nets are linked together by communication between programmable object oriented tokens.
