Using Synthesis and Analysis for Design in Systems Engineering: an Integrated Approach

Abstract

ABSTRACTThis article presents a complete and general approach for the preliminary design of systems in the framework of systems engineering by relying mainly on synthesis. It is completed by a validation step through analysis to reduce furthermore the space of admissible solutions. This approach focuses on the modeling of design problems in electrical engineering and of their solving by including non‐functional requirements right from the start through a single process. Starting from the specification of the requirements, the proposed approach develops the construction of synthesis models of design problems and their solving using the DEPS problem modeling language and the DEPS Studio environment based on Constraint Programming and Object‐oriented modeling. Concepts related to this approach include in particular the issue of reusability of models, notions of subdefinite systems and of problem, knowledge and solutions spaces.
