Business Process Simulation: Transformation of BPMN 2.0 to Discrete Event System Specification

Theoretical modeling is a complicated characteristic of a simulation study that straight affects the quality and effectiveness of simulation projects. This paper presents a model to model transformation from a conceptual modeling language to a simulation model specification. BPMN (Business Process Model and Notation) is worn for theoretical modeling and DEVS (Discrete Event System Specification) is elected for simulation model requirement. Simulation is a dynamic feature of MDSE and which explains the need of coherent M&S formalisms for simulation activities.Accordingly, this paper presents the simulation of service systems based on DEVS models. It defines a transformation approach of BPMN models into DEVS simulation models based on the metamodel approach, and describes the enrichment of obtained DEVS models through performance indicators (time and costs)
