Model-Based Systems Engineering for Systems Simulation
Résumé
Model-Based Systems Engineering and early simulation based Validation & Verification are now key enablers for managing the complexity in the development of modern complex systems like Cyber- Physical Systems. Models provide a formal account of system require- ments and design decisions. Model simulation enables both design ex- ploration and design versus requirements correctness assessment. Model simulation activities rely on Simulation Systems (i.e. systems that exe- cute the model simulation). System execution environment models play a key role during these activities. Appropriate models must be devel- oped for each kind of analysis conducted during Validation & Verifica- tion. More and more often, complex Systems Engineering is conducted in Extended Enterprises and the simulation activities are performed us- ing partial models that must be completed with mock-up models for missing parts of the system. The development of Simulation Systems is thus costly and error prone and would benefit from the same Systems Engineering principles that are applied to the product. We propose a methodology for a seamless integration of the Simulation Systems devel- opment in the Products Systems Engineering. This method imports the available elements from the models of the system and its environment, from the Systems Engineering for Product space to a dedicated Systems Engineering for Simulation space. The required mock-up models are then defined in the Systems Engineering for Simulation space. As a result, we target a better management and reuse of the various environment and mock-up models in the various simulation activities during the devel- opment of the same product. This proposal is independent both of the actual methods and tools used to model the system and of the simulation environment.
