  Designers, process planners and manufacturers naturally consider different
concepts for a same object. The stiffness of production means and the design
specification requirements mark out process planners as responsible of the
coherent integration of all constraints. First, this paper details an
innovative solution of resource choice, applied for aircraft manufacturing
parts. In a second part, key concepts are instanced for the considered
industrial domain. Finally, a digital mock up validates the solution viability
and demonstrates the possibility of an in-process knowledge capitalisation and
use. Formalising the link between Design and Manufacturing allows to hope
enhancements of simultaneous Product / Process developments.
