Abstract : At the present time, in order to manage the functional and structural complexity associated with the design and development of a complex system such as an aircraft, companies put in place organisations that are themselves highly complex - both hierarchical and distributed. Thus, system development is outsourced to different teams from companies that are specialised in different, complementary areas. These teams work according to the principle of concurrent engineering and must coordinate their activities during the design phase (exchange of intermediary results concerning sub-systems at various levels of maturity) and the integration phase (working together on "plateaux"). The present study focuses primarily on the steering of engineering activities within a team, taking into account general constraints related to resources (number of people allocated) and lead times (time slots assigned to activities), as well as the synchronisation constraints inherent to interdependency between the teams. The originality of this study lies in the energetic characterisation it offers of the activities and the constraints that link them, and the fact that it validates the consistency of the steering decisions (activities brought forward or set back, allocation of additional resources) through a rigorous tool based on constraints programming. The constraints propagation devices can be used to validate different simulations in order to be used as a reference for the renegotiation of constraints when such renegotiation becomes mandatory. We also offer an initial specification of the operating procedure for a decision support system tool. We conclude by studying possible extensions of the model as well as the experimentation and validation work that must accompany this study in order to obtain an operational tool that can be circulated among all the teams that are partners in a complex system development project.
