XML format for notation of object-oriented Petri net

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
Petri nets provide executive facilities for simulation of causality, non-determinism and parallelism in discreet systems. Since they are a mathematical model in substance, they offer theory, which can be successfully used to verification of models ...

Representation and structuring of knowledge in the semantic oriented computing environment. Part 1. Integration conceptual graphs and logical networks based on formalization of structured situations

open access: yesИзвестия высших учебных заведений. Поволжский регион:Технические науки, 2023
Background. A technique for deep knowledge structuring in a semantic-oriented intelligent computing environment based on the expansion of the descriptive capabilities of Petri nets by integrating them with conceptual graphs is proposed.

Help students learn interpreted Petri nets with Minecraft

open access: yesInformatics in Education, 2022
Background: Petri nets are a formal specification technique for modelling of control processes and modern flexible manufacturing systems. Interpreted Petri nets take into account input and output signals, allowing to apply them in any control system or ...

Petri nets are monoids

open access: yesInformation and Computation, 1990
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

open access: yesAdvances in Mechanical Engineering, 2017
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.

Fuzzy output system on the basis of the modified fuzzy Petri nets [PDF]

open access: yesE3S Web of Conferences, 2020
The development of information technologies requires improvement of simulation methods and mathematical apparatus. The mathematical apparatus of Petri nets is used for simulation of parallel asynchronous systems and has a broad scope.

DESIGN AND IMPLEMENTATION OF DEADLOCK CONTROL FOR AUTOMATED MANUFACTURING SYSTEMS

open access: yesSouth African Journal of Industrial Engineering, 2019
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.

Stratified petri nets

open access: yes, 1997
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.

Petri Nets and Bisimulations

open access: yesBRICS Report Series, 1994
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.
