System-by-design methodology for multiscale and multiphysics synthesis problems

摘要

The instantiation/customization of the recently introduced System-by-Design (SbD) paradigm to the solution of multiscale and multiphysics synthesis problems is discussed in this work. Towards this end, the SbD fundamental concepts are illustrated (starting from the composition of elementary functional blocks up to the derivation of an integrated SbD design loop) together with the basic structure and components of the associated SbD-inspired synthesis methodologies. The derivation of multiscale and multiphysics SbD-based task-oriented design techniques is then introduced, and its application is discussed also through a numerical example. Advantages, drawbacks, open challenges, and current trends in the research concerning SbD are reviewed specifically focusing on multiscale/multiphysics applicative scenarios.
