BPMN and Simulation

Lanner submission BPMN Simulation.pdf

This paper describes the experiences and technical challenges encountered by the Lanner group in building a Java based simulation engine to simulate BPMN diagrams.
It highlights the difference between conventional discrete simulation tools and the requirements for the BPMN engine. In particular the need for implicit rather then explicit queuing, the complexities of the patterns of parallel token flow and problems
of valid but infeasible diagrams are discussed. Further the limitations of the BPMN standard for producing useful simulation models are highlighted, in particular the availability of Resources.
