Towards an Ontology-Driven Framework for Simulation Model Development

International audienceAn ontology driven domain model approach for improving the fidelity of the simulation by developing models through the inclusion of simulation objectives for the system Verification & Validation activities (V&V) is presented. The system V&V by simulation ontology used to build this domain model is briefly outlined in the system teleological framework of Structure, Behavior, Function, Interface and Operation. The concept of operating mode is proposed and discussed with an example. The ontology approach is demonstrated with an aircraft nacelle anti-ice system presented in the experimental frame formalism. An example of using the inference and query capabilities of the domain model approach to identify and justify abstractions consistent with the test scenarios is illustrated with a failure mode case study for this application case. The relationship with formal behavioral approach through operating modes is briefly discussed at the end where some theoretical results on the behavioral compatibility of the experimental frame components with interface simulation distances are briefly presented. The paper concludes with a discussion on the benefits of this approach from an industrial perspective along with an overview of the challenges ahead and the future work
