A TAOPN Approach to Modeling and Scheduling Cyber-Physical Systems

Zhilin Qian, Huiqun Yu
2013 2013 International Conference on Information Science and Applications (ICISA)  
This approach extends Petri net with time constraints based on aspect-oriented method.  ...  Due to this feature, we propose a timeconstrained aspect-oriented Petri net (TAOPN) approach to model cyber-physical system.  ...  Here the case is given in a medium-grained level. In fact the comprehensive system model can be refined or abstracted to fine-grained or coarse-grained using hierarchical techniques.  ...

Petri-nets as an Intermediate Representation for Heterogeneous Architectures [chapter]

Peter Calvert, Alan Mycroft
2011 Lecture Notes in Computer Science  
We use Petri-nets as an intermediate representation for programs to give a unified view of all forms of performance non-determinism. This includes some scenarios which other models cannot support.  ...  Placement, scheduling and indeed algorithm choices affect the overall execution time and, for portable programs, must adapt to the target machine at either load-time or run-time.  ...  We thank the Schiff Foundation, University of Cambridge, for funding this research through a PhD studentship. Thanks are also due to Jonathan Hayman for valuable discussions and feedback.  ...

DAG Synchronization Constraint Language for Business Processes

Qinyi Wu, A. Sahai
2006 The 8th IEEE International Conference on E-Commerce Technology and The 3rd IEEE International Conference on Enterprise Computing, E-Commerce, and E-Services (CEC/EEE'06)  
We propose DSCL (Dag-acyclic-graph Synchronization Constraint Language) to achieve three desirable properties for a synchronization modeling language: declarative syntax, fine granularity and validation  ...  The relationships are automatically translated into Petri Nets and simulated in the CPN/Tools, from which several correctness criteria can be validated for the composite process.  ...  DSCL integrates the support for fine-grain synchronization as part of DFV properties.  ...
