Stochastic Petri Nets: Modelling, Stability, Simulation

Modelling Opacity Using Petri Nets

We consider opacity as a property of the local states of the secure (or high-level) part of the system, based on the observation of the local states of a low-level part of the system as well as actions. We propose a Petri net modelling technique which allows one to specify different information flow properties, using suitably defined observations of system behaviour. We then discuss expressiven...

Modelling Gradients using Petri Nets

Motivated by the graded posteriorization during the AP axis development in the frog Xenopus laevis, we propose an abstract Petri net model for the formation of a gradient of proteins in a chain of cells.

System Modelling with Petri Nets

Petri Nets (PN) are a graphical formalism which is gaining popularity in recent years as a tool for the representation of complex logical interactions (like synchronization, sequentiality, concurrency and conflict) among physical components or activities in a system. This notes are devoted to introduce the formalism of Petri nets with particular emphasis on the application of the methodology in...

Railway Network Modelling Using Petri Nets

This paper deals with the use of Petri nets in modelling railway network and designing appropriate control logic for it to avoid collision. Here, the whole railway network is presented as a combination of the elementary models – tracks, stations and points (switch) within the station including sensors and semaphores. We use generalized mutual exclusion constraints and constraints containing the...
