Four Steps Towards Sound Business Process Models [chapter]

Juliane Dehnert
2003 Lecture Notes in Computer Science  
The key concept for the proposed process model is the use of pragmatic correctness criteria, namely relaxed soundness and robustness.  ...  The proposed process model supports this refinement step, applying methods from controller synthesis.  ...  Based on these notions, it is now possible to express non-controllable choice robustness of a WF-system. Definition 5.5 (Non-controllable choice robustness).  ...

2004 International Journal of Cooperative Information Systems  
The methodology consists of five steps and is illustrated using event-driven process chains as a business process modeling language and Petri nets as the workflow specification language.  ...  This paper presents a methodology to bridge the gap between business process modeling and workflow specification.  ...  Based on these notions, it is now possible to express non-controllable choice robustness of a WF-system.

Security Provisioning in Pervasive Environments Using Multi-objective Optimization [chapter]

Rinku Dewri, Indrakshi Ray, Indrajit Ray, Darrell Whitley
2008 Lecture Notes in Computer Science  
We propose the use of workflow profiles to capture the contexts in which a communication channel is used in a pervasive environment.  ...  Our approach is based on the formulation of a set of constrained multi-objective optimization problems to minimize the residual damage and the cost of security provisioning.  ...  The views and conclusions contained in this document are those of the authors and should not be interpreted as representing official policies of the U.S.  ...

Transactional Workflows or Workflow Transactions? [chapter]

Paul Grefen
2002 Lecture Notes in Computer Science  
The fact that these processes require robustness and clear semantics has generally been observed and has lead to the combination of workflow and transaction concepts.  ...  To deal with this problem, we describe a clear taxonomy of transactional workflow models, based on the relation between workflow and transaction concepts.  ...  Maarten Fokkinga is acknowledged for his assistance with respect to language concepts and his feedback on the draft version of this paper.  ...
