Une approche paradigmatique de la conception architecturale des systèmes artificiels complexes

Abstract : Architecting seeks now to be distinct from its original domain, systems engineering, becoming an emergent domain. Far from being recognized as a science or a discipline, its practice is nowadays more and more widespread. However, this practice is still poorly formalized, and insufficiently being taught, lacking a well-established and accessible corpus of knowledge, techniques or approaches.This thesis contributes filling that gap by proposing a paradigm of the architectural design of artificial complex systems. The latter is built based on existing paradigms that are combined, then completed. It aims at providing architects with an effective, even performative framework. It results in an approach of the architectural design structured in four levels.A so-called archetypal level grasps the core principles of any approach of architectural design of artificial complex systems. These principles are derived from various approaches already applied, mainly in the field of system or product design, but also of architectural design of buildings.A so-called general level lies on the principle of a present-future division. In that sense, it differs from engineering approaches that usually rely on a problem-solution dichotomy. It is based on the following main idea: we should consent that when an architect designs, he does not solve problems, but he devises possible and plausible futures, requiring to perceive the present. This vision of the architect's way of working directly impacts the kind of artefacts he handles. We sho how to aggregate these artefacts into models, reflecting either his perception of the present, or his development of futures while progressing through some identified processes.A so-called particular level aims at allowing the storytelling of a given design. To achieve this goal, a notation of the design process is suggested. It lies on some basic mechanisms, one of them being the combination divergence-convergence, called the breathing of the architectural design.At last, a so-called toolbox level, not addressed in this thesis, would consist of various cognitive operations required for the architect in order to accomplish his task of designing (abstraction, questioning, judgement, comparison, decision, etc.)The whole approach is illustrated by an example of an architectural design of a complex system: a Safe City.
