Information and Computation, 1990 AbstractPetri nets are widely used to model concurrent systems. However, their composition and abstraction mechanisms are inadequate: we solve this problem in a satisfactory way. We start by remarking that place/transition Petri nets can be viewed as ordinary, directed graphs equipped with two algebraic operations corresponding to parallell and ...

Performance Evaluation of Discrete Event Systems with GPenSIM
Computers, 2018 Petri nets are a useful tool for the modeling and performance evaluation of discrete event systems. Literature reveals that the Petri Net models of real-world discrete event systems are most frequently event graphs (a subclass of Petri nets).

Petri Net Modeling for Ising Model Formulation in Quantum Annealing
Applied Sciences, 2021 Quantum annealing is an emerging new platform for combinatorial optimization, requiring an Ising model formulation for optimization problems. The formulation can be an essential obstacle to the permeation of this innovation into broad areas of everyday ...

Unfolding-Based Process Discovery [PDF]
, 2015 This paper presents a novel technique for process discovery. In contrast to the current trend, which only considers an event log for discovering a process model, we assume two additional inputs: an independence relation on the set of logged activities ...

SYNCHRONIZATION IN PETRI NETS [PDF]
Fundamenta Informaticae, 1996 In “Petti nets are Monoids” by Meseguer and Montanari, categories for Petri nets with and without markings are introduced, where the categorical product and coproduct express the joint behavior of nets. However, this framework lacks structure in the sense that there is no categorical technique to define a composition of nets satisfying some given ...

DESIGN AND IMPLEMENTATION OF DEADLOCK CONTROL FOR AUTOMATED MANUFACTURING SYSTEMS
South 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.
