In this section, we study several simple examples that are given to introduce some basic concepts of Petri nets that are useful in modeling. subclass of Petri nets. As an example of a finite-state machine, consider a vending machine, which accepts either nickels or dimes and sells 15-cent or 20-cent candy bars.
Petri net synthesis: Concurrent vending machine - Workcraft
Simulate your model to make sure that the concurrent actions can happen in any order, and that the Vending Machine processes the orders correctly. Formally verify whether the FSM. FSMs can be considered as a special case of Petri nets where each transition has exactly one incoming and one outgoing arcs and the initial marking consists of one token.

Petri nets are an advanced transition system whose semantics are determined by making explicit the preconditions enabling an operation to be carried out while leaving implicit how independent operations are timed. This way Petri nets provide a natural view on concurrent behavior.

This work defines a class of Petri nets called interactive Petri nets (IPNs) to model these systems. IPNs can be used to analyze their behavior, find potential problems, and then improve...
7: A Petri net for representing the behaviour of a vending machine
In this paper, we propose a new algorithm that enables an architect to transform a component diagram into an executable model based on different extensions of petri nets. Moreover, we show how...

This paper focuses on the use of Deterministic timed Petri net (DTPNs) to model a coffee vending machine system. The advantage of the proposed approach is that the clear presentation of the behaviors of the coffee vending machine in terms of conditions and transitions that cause the state alternations.
Place/transition Petri nets (p/t-nets, forshort) are the most prominent and best studied class of Petri nets. This class is ometimes just called P tri nets. In contrast to elementary (Petri) net systems [RoEn98], inp/t-nets aplace can hold any number of tokens. In contrast to high-level Petri nets [$ens98], these tokens are indistinguishable.
Petri nets are semantic structures widely used in computer science. Their ade-quacy to model, specify and analyze complex systems dealing with concurrency and resource awareness is well known. At the core of this success is their rich and intuitive graphical syntax.
