Like a system model in  Information Systems  and  Software Engineering  (IS/SE), a system model in simulation engineering mainly consists of an  information model  and a  process model . In the fields of IS/SE there are widely used standards such as the  Class Diagrams  of the  Unified Modeling Language (UML)  for making information models, and the  Business Process Modeling Notation (BPMN)  for making process models. This tutorial shows how to use UML class diagrams and BPMN process models at all three levels of  model-driven simulation engineering : for making conceptual simulation models, for making platform-independent simulation design models, and for making platform-specific, executable simulation models.
