RESUME La conception et developpement en tant qu'activite essentielle et motrice du cycle de vie du produit est desormais profondement influencee par les outils informatiques et leur utilisation par les divers acteurs, internes ou externes a l'entreprise et a travers les phases de vie du produit. Dans un contexte ou chaque domaine d'expertise possede ses propres outils specialises, de nouveaux defis relatifs a la collaboration et a la dissemination de l'information sont presents. Ces defis vont crescendo aussi bien a cause de la croissance, la multiplicite et les relations entre les donnees generees que le souci de gerer leurs flux et des processus cles tels que le changement. A cet effet, les travaux presentes sont bases sur les transactions specifiques d'un departement de developpement et tests dont les activites consistent a planifier et construire des prototypes afin de valider des performances fonctionnelles et operationnelles du produit. Il s’agit donc de proposer et simuler une plate-forme s'appuyant sur les donnees configurees d'ingenierie, les structures d'information complementaires et l'ensemble des pratiques modernes de gestion de donnees techniques pour converger vers des solutions et concepts repondant aux defis souleves. Cette convergence devra en outre adherer durablement a l'optique de gestion de cycle de vie du produit (PLM, Product Lifecycle Management). Dans un premier temps, une etude d'un cas de conception d'un nouveau pylone pour le remplacement d'un moteur de serie d'avion est menee afin de detailler et implementer, autant que possible, les fonctionnalites cles de la plate-forme cible. Cette simulation, mettant en exergue les structures complementaires et configurables, est realisee sur un systeme PLM recent a disposition pour le projet. Dans un second temps, une etude basee sur les logiciels libres et s'appuyant sur un modele de communication prealablement justifie est deployee afin de demontrer comment des donnees nativement incompatibles peuvent etre transformees, homogeneisees et gerees de maniere consistante dans un emplacement commun. L’approche telle qu'implementee en deux temps permet d'effectuer transpositions et extrapolations de maniere a introduire l'Open Exchange Nest en tant que concept generique apte a supporter le travail collaboratif au sens PLM.ABSTRACT The modern perspective on product life cycle and the rapid evolution of Information and Communication Technologies in general have opened a new era in product representation and product information sharing between participants, both inside and outside the enterprise and throughout the product life. In particular, the Product Development Process relies on crossfunctional activities involving different domains of expertise that each have their own dedicated tools. This has generated new challenges in terms of collaboration and dissemination of information at large between companies or even within the same organization. Within this context, the work reported herein focuses on a specific stakeholder within product development activities - the prototyping and testing department. Its business is typically related to the planning and building of prototypes in order to perform specific tests on the future product or one of its sub-assemblies. The research project aims at investigating an appropriate framework that leverages configured engineering product information, based on complementary information structures, to share and exchange prototyping and testing information in a Product Lifecycle Management (PLM) perspective. As a first step, a case study based on the retrofit of an aircraft engine is deployed to implement a scenario demonstrating the functionalities to be available within the intended framework. For this purpose, complementary and configurable structures are simulated within the project’s PLM system. In a second step are considered the software interoperability issues that don’t only affect Design – Testing interactions, but many other interfaces within either the company – due to the silo-arrangement – or the consortiums with partners, in which case the whole PLM platforms could simply be incompatible. A study based on an open source initiative and relying on an improved model of communication is described to show how two natively disparate PLM tools can dialogue to merge information in a central environment. The principles applied in both steps are therefore transposed to introduce the Open Exchange Nest as a generic PLM-driven and web-based concept to support the collaborative work in the aforementioned context.
