INCOSE IW 2012 MBSE Workshop Where do we stand today  Clear separation of model and representation / use of model  Respect of domain specific models and languages  Good understanding of process  Identified the challenge of data interoperability  Ongoing Projects  ESA ‘Virtual Spacecraft Design’ (VSD): Multidisciplinary modelling and model exploration tool  EU project Verde: Improving Design – Analysis Iterations and link to Modelica  Spin-off in use in operational context (e.g. System DB)

Where are we going  Integration of more analysis tools  Extension to all verification methods (testing…)  Configuration / model management  Evolution of Conceptual Data Modeling Languages (e.g. OWL, SIMF, Ecore++)  Interoperability / convergence of engineering models and ontologies  Introduction in industrial SE process and in customer / supplier relationship on all levels INCOSE IW 2012 MBSE Workshop
