This thesis presents a design decision framework for assessing alternative manufacturing and remanufacturing strategies from both technical and business perspectives. The proposed methods enable such considerations in the early product design phases, where a sufficient degree of freedom exists to identify component design solutions that can accommodate dynamic requirements throughout a product's life.The first method presented in this thesis considers the potential use of additive manufacturing in life extension strategies by examining the impact of design decisions on component lifecycle cost. An optimization problem is formulated and solved to minimize lifecycle cost with respect to design variables related to remanufacturing.The second design decision method proposed enables the consideration of a design margins approach to satisfy changing requirements through optimizing component lifespan for different lifecycle scenarios. A dynamic lifecycle cost model that considers additive remanufacturing to quantify corresponding costs and benefits is developed. A nested design optimization problem is then formulated to determine the optimal component lifespan range that minimizes overall cost while maximizing performance. The proposed methods are demonstrated using a turbine rear structure, an aeroengine structural loadbearing component. The life extension of the turbine rear structure is achieved through the additive deposition of a circumferential stiffener on the outer casing.Design and manufacturing scenarios have a significant impact on the efficiency of the manufacturing process. Therefore, an integrated design-manufacturing decision metric is proposed to allow assessment of products based on both the geometrical information obtained from a part's computer aided design file and its manufacturing scenario. The developed metric can be used as a proxy of build time and manufacturing cost assisting in the product's design optimization and development processes. Two examples of jet engine components are used to illustrate the use and benefits of the proposed decision metric. The presented methods and metric support design decision-making while considering the potential use of new technologies in addressing changing requirements throughout a component's life.

520 $a Cette these presente un cadre de decision de conception pour evaluer des strategies de fabrication et strategies de refabrication des deux perspectives techniques et commerciales..... Les methodes proposees permettent de telles considerations dans les premieres phases de conception du produit, ou un degre de liberte suffisant existe pour identifier des solutions de conception de composants qui peuvent repondre aux exigences dynamiques tout au long de la vie d'un produit. La premiere methode presentee dans cette these considere l'utilisation potentielle de la fabrication additive dans les strategies de prolongation de la duree de vie en examinant l'impact des decisions de conception sur le cout du cycle de vie des composants. Un probleme d'optimisation est formule et resolu pour minimiser le cout du cycle de vie en respectant les variables de conception liees a la refabrication. La deuxieme methode de decision de conception proposee permet d'envisager une approche des marges de conception poursatisfaire aux exigences changeantes en optimisant la duree de vie des composants pour differents scenarios de cycle de vie. Un modele de cout du cycle de vie dynamique qui prend en compte la refabrication additive pour quantifier les couts et avantages correspondants est developpe. Un probleme d'optimisation de conception imbriquee est ensuite formule pour determiner la gammede duree de vie optimale des composants qui minimise le cout global tout en maximisantles performances. Les methodes proposees sont demontreesal'aide d'unestructure arriere de turbine, un element porteur structurel de moteur aeronautique. L'allongementde la duree de vie de la structure arriere de la turbine est obtenu grace au depot additif d'un raidisseur circonferentiel sur le tubage exterieur. Les scenarios de conception et de fabrication ont un impact significatif sur l'efficacite du processus de fabrication. Par consequent, une metrique de decision de conceptionfabrication integree est proposee pour permettre l'evaluation des produits sur la base a la fois des informations geometriques obtenues a partir du fichier de conception assistee par ordinateur d'une piece et de son scenario de fabrication. La metrique developpee peut etre utilisee comme une procuration du temps de construction et des couts de fabrication pouraider a l'optimisation de la conception du produit et aux processus de developpement. Deux exemples de composants de moteursareaction sont utilises pour illustrer l'utilisation et les avantages de la mesure de decision proposee. Les methodes et metriques presentees soutiennentla prise de decision en matiere de conception tout en considerantl'utilisation potentielle des nouvelles technologies pour repondre aux besoins changeants tout au long de la vie d'un composant.
