Conception Architecturale de Systèmes Complexes par une Approche Energétique : Application au Domaine Aéronautique.

Abstract : The architectural design of complex systems presents many difficulties and conventional design methods can only provide a limited response to the current issues. Many methodologies offer solutions by focusing on one facet of the development process or a specific design criterion. Globalization and population growth require high production rates from manufacturers, while new consumption patterns require a high degree of agility to adapt quickly to customer needs. These constraints highlight the limits of the current design paradigm and highlight the issues arising from the product development process. The decorrelation between the different views of the product (functional, physical and industrial) encourages the appearance of inconsistencies and makes an already highly constrained process more complex. This research proposes to link the different views of the product during its development in order to reinforce the robustness of the design, to promote collaborative design and to improve the traceability of the design choices during the development of a product. The CTOC (Converter, Transmitter, Operator, Control) approach formalized here echoes this proposal by offering a robust design framework allowing to build simultaneously the functional and physical views of the product. Developments of the CTOC method are presented in this thesis in order to respond to the issues identified in the context of the study but also to provide a design environment conducive to architectural innovation.The design choices made during the architectural design phase impact the whole development and the consequences of these choices may not appear until much later. Thus, the industrialization phase of the product may reveal unsatisfactory industrial performance, the origin of which can be traced back to design choices made at the beginning of the development process. The integration of industrial performance evaluation criteria as early as the preliminary design phase allows designers to discriminate candidate architectures very early on and to evaluate their industrial performance. The work presented in this thesis brings developments to the CDfA (Conceptual Design for Assembly) method which focuses on the evaluation of the industrial performance of assembly and proposes a method that can be extended to other criteria in the future.The identification of a strong synergy between the CTOC and CDfA approaches has allowed to group them into a global architectural design methodology. The use of the CTOC model as a basis for the application of the CDfA approach brings many advantages and in particular a greater mastery of a system despite its complexity. The global CTOC model fulfils the necessary conditions for the application of the industrial performance assessment methodology described by the CDfA approach. This work formalizes a global architectural design methodology linking the functional, physical and industrial views of the product and applicable from the preliminary design phase.
