A new definition of place/transition Petri nets as graphs with the operation of parallel and sequential composition on the transitions is given. New morphisms, relating system description at different level of abstractions, and new constructions, like function space for Petri nets, are defined.

A class of generalized Petri nets and its state equation
By analyzing the evolution nature of a Petri net, this article reports a generalized state equation for Petri nets, including Petri nets with inhibitor and enabling arcs.

Evolving concurrent Petri net models of epistasis [PDF]
A genetic algorithm is used to learn a non-deterministic Petri netbased model of non-linear gene interactions, or statistical epistasis. Petri nets are computational models of concurrent processes.

A new approach for diagnosability analysis of Petri nets using Verifier Nets [PDF]
In this paper, we analyze the diagnosability properties of labeled Petri nets. We consider the standard notion of diagnosability of languages, requiring that every occurrence of an unobservable fault event be eventually detected, as well as the stronger ...

Event structures for Petri nets with persistence [PDF]
Event structures are a well-accepted model of concurrency. In a seminal paper by Nielsen, Plotkin and Winskel, they are used to establish a bridge between the theory of domains and the approach to concurrency proposed by Petri.

Information Systems Development with the Help of Petri Nets [PDF]
Many present software systems can be developed by a sequence of transformations from the source specification to the final implementation. An interesting question is whether we can support such a sequence of transformations by some formal apparatus that ...

Several categorical relationships (adjunctions) between models for concurrency<br /> have been established, allowing the translation of concepts and<br />properties from one model to another. A central example is a coreflection<br />between Petri nets and asynchronous transition systems.

DESIGN AND IMPLEMENTATION OF DEADLOCK CONTROL FOR AUTOMATED MANUFACTURING SYSTEMS
Petri nets are robust mathematical tools for the modelling, handling, and control of deadlock problems in automated manufacturing systems (AMSs). Several methods have been proposed to prevent deadlocks in AMSs.

We introduce a subclass of Valk's self-modifying nets. The considered nets appear as statified sums of ordinary nets and they arise as a counterpart to cascade products of automata via the duality between automata and nets based on regions in automata.
