Petri net based Grid workflow verification and optimization

Haijun Cao, Hai Jin, Song Wu, Shadi Ibrahim
2011 Journal of Supercomputing  
In addition, we present our Grid workflow analysis approaches on three aspects: workflow reachability verification, workflow deadlock verification, and workflow optimization.  ...  Graphical workflow modeling tools, such as UML and DAG, can facilitate users to express workflow process logic, but lack of abilities to carry out simulation and correctness checking.  ...  Based on Petri net, we proposed service composition oriented Grid workflow net.

Petri net-based semantics for verification and validation of workflow patterns

Ahmed Nait Sidi Moh
2013 International Journal of Services Operations and Informatics  
We propose a high-level class of Petri nets for describing the behaviour of scenarios of web services composition. Developed models support the strong dynamic and temporal aspects of these scenarios.  ...  To address this issue, this paper provides a mapping from activities to Petri net models. Formalisations basing on UML and Petri nets of control-flow patterns for service composition are addressed.  ...  Kovacs et al. (2008) presented an approach for the verification of business workflows.  ...
