Designing physical systems through a model-based synthesis approach. Example of a Li-ion battery for electrical vehicles
Résumé
This paper presents an approach for the preliminary design of complex physical systems in the framework of
systems engineering. This approach is centered on the activities and actors involved in the pre-design tasks. It
focuses on the modeling of design problems with DEPS (DEsign Problem Specification), a recent formalism for
specifying and modeling design problems in engineering. This design methodology completes simulation-based
analysis approaches, which are mainly used today for the design of physical systems. In particular, our approach
allows the synthesis of pre-design architectures, which analysis/simulation approaches cannot do. Starting from
the textual specification of the requirements, the proposed approach builds a formal model of the design problem
and solves it using Constraint Programming. Ideas and concepts related to this approach are discussed: the issue
of reusability of problem models, the concepts of problem, knowledge and solutions spaces as well as the formal
specification of requirements and everything else that distinguishe a design problem model from a designed system
model. An example of a Li-ion battery design for an electric vehicle acts as a practical use case for this article.
