Protocol Performance Analysis Using a Timed Extension for an Object Oriented Petri Net Language

Fabrício Vale de Azevedo Guerra, Jorge Cesar Abrantes de Figueiredo, Dalton Dario Serey Guerrero
2005 Electronical Notes in Theoretical Computer Science  
In this paper we propose a timed extension for RPOO, a Petri-net based object-oriented modeling language.  ...  RPOOt showed to be easily integrated with Timed Coloured Petri Nets, providing means for modeling time consuming activities inside objects as well as among objects.  ...  Since the main objective is to use TCP-nets to describe the objects behavior, the Petri net models that represent the objects internal behavior in this case study are strongly influenced by the models  ...

Formal schedulability analysis based on multi-core RTOS model

Imane Haur, Jean-Luc Béchennec, Olivier Henri Roux
2021 29th International Conference on Real-Time Networks and Systems  
The operating system as a whole is modeled by a High-level Petri net reproducing the control flow and using the same variables as those of the implementation.  ...  Each task of the application is represented by a Stopwatch Petri Net whose transitions carry Best-Case Execution Time and Worst-Case Execution Time [𝐵𝐶𝐸𝑇 ,𝑊 𝐶𝐸𝑇 ] firing intervals and make service  ...  The term High-level Petri net is then used for many Petri nets [19] such as Predicate/Transition Nets, colored Petri nets, or hierarchical Petri nets.  ...

Interpreted collaboration protocols and their use in groupware prototyping

Richard Furuta, P. David Stotts
1994 Proceedings of the 1994 ACM conference on Computer supported cooperative work - CSCW '94  
The correct and timely creation of systems for coordination of group work depends on the ability to express, analyze, and experiment with protocols for managing multiple work threads.  ...  In Trellis, group interaction protocols are represented separately from the interface processes use them for coordination.  ...  Semantic nets and link typing may be as useful for pure hypertext description. Object-based message passing languages are probably as appropriate for expressing parallel threads.  ...

Automatic Transformation of Ordinary Timed Petri Nets into Event-B for Formal Verification

Chalika Saksupawattanakul, Wiwat Vatanawood
2018 Engineering Journal  
From a practical point of view, the timed Petri net is commonly used to graphically model and illustrate the view of the timed behavior of real-time software systems, which is a good basis for an understanding  ...  However, there is a lack of development process software for the simulation of a timed Petri net.  ...  The Petri nets formalism is common to the formal model specifications for the concurrent system, with no time constraints in the first place.  ...

Flexibility in Process-Aware Information Systems [chapter]

Manfred Reichert, Stefanie Rinderle-Ma, Peter Dadam
2009 Lecture Notes in Computer Science  
This often leads to rigid behavior or gaps between real-world processes and implemented ones.  ...  In response to this drawback, adaptive PAIS have emerged, which allow to dynamically adapt or evolve the structure of process models under execution.  ...  process schema S [18] ; i.e., S obeys the specific correctness constraints set out by the used process meta model (e.g., bipartite graph structure for Petri Nets).  ...
