The design of embedded mechatronics systems is a complex process. Indeed, such systems have multi-domain, multi-physical and multi-scale characteristics. Therefore, a multi-level, multidisciplinary and pluri-technological approach is necessary in order to achieve a holistic design. The motivation of developing an unconventional preliminary sizing approach is to enable knowledge capitalization and offer engineers the possibility to optimize their mechatronic products design with a more integrated design approach. Generally, models used during preliminary design of such multi-domain systems come from several disciplines and have different scales: distributed parameters (3D FEM, 3D CFD) for local level, lumped parameters (1D/0D, ODE/ADE) and state machine for global level. The dynamic simulation through 0D-1D models of the system to be designed is commonly used to validate architectural choices and preliminary sizing that requires multi-disciplinary optimization. Unfortunately, optimization can not only apply to the system level and resort to 3D models cannot be avoided, even during the early design phases. rnThe proposed more integrated design approach aims to illustrate how a system architect could evaluate the sizing of a given system whilst being positioned between the requirements engineering tools and domains specific detailed design tools. This approach will be underlined through the design of an electrical thrust reverser actuation system.rn
