Abstract:

L'optimisation multi-disciplinaire propose des solutions aux problèmes de conception de systèmes complexes. Le terme « optimisation multi-disciplinaire » laisse sous-entendre à tort qu'il ne s'agit que d'un problème d'optimisation. Nous lui préférons ici le terme de « conception collaborative ». En effet, l'optimisation ne représente qu'un aspect, qui ne peut être séparée du reste du problème de conception. Le but n'est pas de créer un processus automatique, mais de faciliter les échanges entre les équipes des différentes disciplines. De nombreuses méthodes, appelées communément formulations MDO (de Multi-Disciplinary Optimization), apparaissent dans la littérature (MDF, IDF, AAO, BLISS, CO). Elles proposent des stratégies permettant, d'une part, d'assurer la cohérence de la description du système complexe et, d'autre part, d'effectuer la recherche de la configuration optimale. Dans un premier temps, nous dressons un état de l'art des formulations MDO. Nous mettons en avant leurs points communs et leurs différences, afin de proposer une implémentation de la manière la plus générale qui soit. Nous proposons, avec la méthode DIVE (Discipline Interaction Variable Elimination), un cadre d'utilisation de méta-modèles au sein des formulations MDO. Le méta-modèle peut se limiter à une approximation linéaire ou quadratique. Il peut s'appuyer sur des méthodes classiques d'apprentissage, telles que les réseaux neuronaux, le Krigeage ou la SVM. Chaque méta-modèle est accompagné d'une région de confiance qui en détermine la validité. Cette approche par approximations locales et successives permet d'aborder les problèmes de grande dimension. Nous présentons des résultats obtenus avec deux cas-tests d'avions d'affaires supersoniques obtenus sous deux environnements différents (Scilab et ModelCenter).

Abstract:

Depuis les années 1980, de nombreuses municipalités françaises ont réintroduit les tramways comme moyen de contrôler la mobilité urbaine. Mon travail part d'un questionnement général sur la propre maîtrise de ces projets technologiques. L'étude de la première phase du projet " Tramway " de la CUS, paradigme de cette démarche, sert à analyser concrètement la fonction de pilotage sans pour autant se limiter au champ de la gestion. On suit les traces des actions de conduite de tout genre jusqu'à l'espace d'implantation. La notion de " cadre sociotechnique " me permet d'élargir les postulats de la théorie de l'acteur-réseau, à la base de cette étude. Le pilotage est traité sous l'angle de la communication, en termes de production et de mise en circulation des inscriptions du projet (des plannings, des rapports d'études, des maquettes. . . ). Ces éléments qui circulent entre les acteurs sont considérés comme la substance de l'organisation et la base de l'évolution du projet. Dans le réseau ainsi constitué, le pilotage du projet apparaît sous la forme d'une action distribuée et se précise comme un travail de médiation. Outre la coordination entre les acteurs, la communication forge la mise en cohérence du projet. Ses inscriptions configurent un discours du pilotage par lequel s'articule la définition, ainsi que les acteurs et les technologies en lice au sein du cadre sociotechnique. L'analyse du cas d'étude sert certes de guide pour explorer le questionnement général du départ et tester les théories qui lui sont à la base. Mais cette thèse constitue également une proposition pour rapprocher la recherche du monde de la gestion et de la décision politique. Les politiques technologiques, même au niveau urbain, sont souvent axées sur les politiques économiques. Cette thèse contribue à l'effort collectif pour élargir la portée de ces politiques et les ouvrir à une prise en compte plus compréhensive des facteurs qui participent à l'innovation à la fois technologique et sociale
During the last two decades, several French municipalities have reintroduced tramways in order to control urban mobility. A general question about the very mastering of these technological projects is at the origin of my work. The study of the first phase of the Strasbourg's “Tramway” project allows me for a concrete analysis of the steerage function and to overstep the bounders of management. I introduce the notion of “sociotechnical frame” in order to extend the methodological principles of the actor-network theory, which found this study. Project steerage is analysed as a communication process, in terms of production and flux of inscriptions (plannings, reports, models. . . ). These elements circulating among actors are considered the substance of organisation and the base of the project evolution. Within the network so constituted, steerage takes the form of a distributed action and is understood as a work of mediation. Besides coordination, communication enables coherence. The project's inscriptions configure a steerage discourse that articulates its definition as well as the actors and the technologies at stake within the sociotechnical frame. The analysis of this particular case offers a guide to explore the initial general questioning and to test the underlying theories. But this work is also a proposal to bring research closer to management and policy. Technology policy is frequently subordinated to economic policy, even at the urban scale. My dissertation contributes to a collective effort to enlarge the policy scope and open it up to a more comprehensive consideration of the factors taking part in innovation, social and technical at once

Abstract:

En phase d'avant-projet, les constructeurs automobiles veulent avoir accès à une méthodologie de simulation et d'optimisation au choc qui permet d'avoir une idée rapide du comportement des différentes conceptions. Les grandes déformations plastiques localisées lors du choc d'une structure rendent possible l'utilisation de la dynamique des multi-corps en modélisant celles-ci par des ressorts non-linéaires. Nous présentons les coordonnées naturelles qui permettent de décrire rapidement un modèle multi-corps d'une structure automobile avec un minimum de variables. Nous associons à cette description le principe de Kane pour la formulation des équations du mouvement. Nous développons des modèles cinématiques de manière à déterminer analytiquement la résistance à l'effondrement de structures à parois minces, de géométrie complexe, soumises à des chargements de flexion et de compression. Une méthode originale de localisation des grandes déformations plastiques est présentée. Elle couple les résultats analytiques pour les composants locaux et ceux d'un modèle élément finis poutre. Cette méthode détermine le nombre et la position des joints de déformation, afin d'optimiser les temps de calcul, et améliore les caractéristiques des ressorts non-linéaires pour la phase de pré-effondrement pour des chargements complexes. Nous confrontons les modèles analytiques à des simulations numériques ainsi qu'à des essais expérimentaux. En utilisant un exemple d'un longeron en « S » de type automobile, la modélisation multi-corps développée, les modèles analytiques et la méthode de localisation sont validés sur un modèle éléments finis de référence. Les résultats obtenus font de cette approche un outil performant pour une estimation rapide du comportement au choc des structures automobiles
During the design phase, the manufacturer wants to have access to a simulation and crash optimization methodology which enables him to have a quick and rough idea about the behaviour of several alternative designs. The localized large plastic deformation of a structure allows one to apply rigid body dynamics to model large plastic deformation of the structure by using generalized spring elements to represent the plastic characteristics of the structural components. A spatial multibody system with natural coordonates wich are Cartesian coordinates of points and components of vectors is described. This description of the multibody system is used in conjunction with Kane’s method to obtain the dynamical equations of motion. Distinct kinematic models have been developed in order to analytically determine the resistance to collapse of thin-walled structures, of relativity complex geometry, subjected to compression or bending loading. An original method for the localization of the large plastic deformation based on the comparison between analytical results for the local components and a global beam finite element model is presented. The localization method determine the number and position the deformation joints so as to optimize the calculation time and improve the characteristics of the non-linear springs for the pre-collapse stage in the case of dynamic loading and for complexes structures. We validate these analytical models with finite element calculations and experimental tests. Using an example of a double curvature “S” frame undergoing a collision against a rigid block, the spatial multibody modelling and the localization method are tested where translational and rotational springs are supplied by the results of kinematic models and beam elements. After comparison between this simplified modelling’s results and the FE numerical calculations, this approach appears to be a promising tool for rapid estimations of crash behaviour of car structures

Abstract:

L'optimisation constitue un puissant outil d'aide à la conception. Les travaux présentés proposent une stratégie d'optimisation adaptée à l'implantation et au dimensionnement de suspensions de groupes motopropulseurs (GMP). Tout d'abord, une étude bibliographique des méthodes d'optimisation multiobjectifs permet la sélection des méthodes les mieux adaptées à une application aux systèmes dynamiques. Ensuite, une analyse fonctionnelle, et un état de l'art des principes de dimensionnement des suspensions GMP, montrent la nécessité d'obtenir un compromis entre les différentes fonctions attendues d'une suspension GMP. A l'issue de ces deux parties, l'outil multiobjectifs apparaît bien adapté au dimensionnement des suspensions GMP. Une formulation numérique du problème de l'optimisation multiobjectifs d'une suspension GMP en phase d'avant-projet est alors proposée. Elle comprend notamment la modélisation des différents cas de fonctionnement d'une suspension GMP, la formulation des différentes fonctions objectifs et restrictions, ainsi que le calcul des sensibilités de ces fonctions vis-à-vis des variables de conception. Dans cette formalisation, l'accent est mis sur le respect des paramètres usuels et des attentes du concepteur, ainsi que sur la rapidité d'exécution, synonyme de réactivité dans un contexte de conception. Enfin, les stratégies multiobjectifs retenues sont testées sur un cas concret de dimensionnement de suspension GMP. Ces essais sont l'occasion d'apporter des modifications originales à chacune des méthodes afin d'améliorer la qualité des solutions générées, et leur répartition dans l'ensemble de Pareto du problème.

Abstract:

Pendant la phase de conception, 80 % des coûts d'un produit sont engagés par les décisions prises par les concepteurs. De plus, c'est durant cette phase que les possibilités de réduire son coût total sont les plus importantes et que les possibilités d'étude des solutions alternatives et des modifications sont les moins onéreuses. Or, en phase de conception, la définition du produit n'est que partielle, et les conditions et les moyens de production quasiment inconnus. Il est donc essentiel de fournir aux concepteurs des outils d'estimation de coûts efficaces, adaptés à ses connaissances sur le produit, et intégrant l'expertise et les connaissances "métier" de l'entreprise. Après avoir souligné les limites des outils traditionnels d'évaluation économique en phase de conception, le travail réalisé dans cette étude vise à formaliser et à valider une démarche de création d'outils d'estimation de coût spécifiques, intermédiaires aux modèles universels et aux modèles analytiques. L'approche est basée sur la méthode paramétrique des formules d'estimation de coût (FEC) dont le principe général est de fournir des relations mathématiques reliant le coût d'un produit à certains de ses paramètres techniques descripteurs. Dans notre travail, nous avons particulièrement développé les points suivants : 1 - le développement de l'ensemble de la méthodologie de création de modèles spécifiques d'estimation de coûts, depuis la définition du cadre de l'étude et la récupération de données jusqu'à la sélection de formules et leur validation. 2 - l'utilisation de paramètres descripteurs de coût originaux palliant au problème de l'estimation du coût d'un produit partiellement défini. 3 - la mise au point de méthodes de sélection de formules ayant le meilleur compromis qualité statistique/cohérence technique. Enfin, ces différentes approches ont été testées sur une application réelle, l'usinage de pièces prismatiques
Eighty per cent of the costs of a product are detemined by decisions taken by the designers. Moreover, it is during the design phase that possibilities of reducing the total cost are the most important. Early studies of alternative solutions and design modifications are less expensive and more efficient. However, in the design phase, the product is never completely defined and the conditions and means of production are note fully known. Therefore, it is necessary to provide the designer with efficient cost estimation tools adapted to the available knowledge about the product, and including the expertise and the experience of the compagny. After having emphasized the limits of traditional tools for the economic evaluation during design phase, the objective of this work is to formalize and validate the processes for the creation of specific cost estimation tools, which are intermediary between universal models and analytic methods. The approach is based on the parametric method using cost estimation relationship (CER) which model the cost of a product according to some of its technical descriptor parameters. In this work, we have developed the following topics : 1 - the methodology for the creation of specific cost estimation tools, from the definiton of the scope of the study, the collection of data, to the selection of formulae and their validation. 2 - the definiton of new cost drivers palliating to the cost estimation problem of a partially defined product. 3 - practical methods for the selection of cost estimation relationships taking into account the statistical quality criteria and the technical coherence. These approaches have been tested and validated on a real project, the estimation of manufacturing cost for prismatic parts

Abstract:

Cette thèse réalisée dans le domaine du génie industriel traite de l’élaboration d’une méthode d’évaluation des impacts potentiels comme moyen d’aide à la décision dans les phases amont de la conception d’un projet de changement technico-organisationnel. Ce travail a été réalisé dans le cadre d’un projet de recherche technologique et de développement (RT&D) européen intitulé SMMART (System for Mobile Maintenance Accessible on Real Time) et intègre les constructeurs d’équipement d’origine (OEM) de l’industrie du transport aérospatial, routier et maritime. L’étude des transformations des pratiques de maintenance et l’accompagnement du changement constituait notre terrain de recherche. Notre cas d’étude a été réalisé au sein du motoriste Turbomeca appartenant au groupe Safran dont le besoin concernait les possibilités d’anticipation des transformations potentielles issues du projet de recherche européen. Pour répondre à cette demande industrielle nous avons élaboré une méthode collaborative d’anticipation des transformations potentielles structurée en trois phases : exploratoire, spécification des impacts opérationnels et l’analyse de convergence. Nos résultats démontrent que notre méthode en trois paliers évolutifs permet l’analyse de la vision partagée des impacts potentiels des communautés d’acteurs de maintenance et l’anticipation des changements potentiels
This thesis developed in the field of industrial engineering deals with the elaboration of a potential impact evaluation method as a mean of decision making support in the early phases of technical & organisational change project design. This work was undertaken within a European technological research and development project entitled SMMART (System for Mobile Maintenance Accessible on Real Time). It integrates original engine manufactures (OEM) from road, marine and aeronautic industry. The study of the maintenance practice transformations and the related change management represents our research investigation field. Our case study was based on an engine manufacturer needs belonging to the Safran group, named Turbomeca. Its needs were related to the anticipation capabilities of the potential change generated by the European project. To answer to that industrial demand we have elaborated a collaborative potential change anticipation method structured in three phases: exploratory, impacts specification and convergence analysis. Our results demonstrate that the applied three evolutive phases method allows the analysis of the community of maintenance actors shared vision of potential impacts and the anticipation of potential change

Abstract:

Cette recherche porte sur l'évaluation de la durabilité en phase amont d'un projet architectural. Cette thèse argumente la nécessité d'évaluer l'impact sur les aspects de développement durable en phase de préconception. La phase amont est très importante en raison de son faible coût et des degrés de liberté qu'elle permet lors des prises de décisions. Ainsi l'élaboration d'un outil ou d'un modèle pouvant aider les architectes à identifier les potentiels de durabilité en préconception, représente un enjeu important pour l'aide à la décision architecturale. En prenant en compte les impacts de la durabilité en phase amont, le concepteur peut s'astreindre à une vision différente et peut aborder des espaces de solutions visant à augmenter le niveau de durabilité de son projet. La méthode de conception à objectif désigné (COD) est utilisée en tant que démarche pour structurer l'outil d'aide à la décision. Cet outil aide les architectes à guider leur choix en fonction d'objectifs pré-établis. De plus, grâce à la COD, tous les acteurs du domaine de la construction peuvent participer à la phase de la programmation. D'autre part, l'accent peut être mis sur l'aspect socioculturel que les méthodes existantes ont négligé. Notre outil a été développé sous forme de logiciel puis a été expérimenté sur quatre projets réels en Iran. Les résultats bruts attestent de la pertinence de l'outil en phase de préconception
This research focuses on sustainability assessment in the upstream phase of an architectural project. This thesis points out the need to assess the impacts of pre-design's phases decisions on the sustainable development aspects. The upstream phase is very important because of their low cost and the large range of possible solution. As a consequence a tool or model is required that can help designers/Architects to identify sustainability potential in pre-design phase : this will constitute a "Decision aids tool" for architecture. Taking into account the impacts of sustainability in the upstream phase, the designer/Architects can achieve a different view and take advantage of these environmental effects to increase the level of sustainability of the project. The "Design to Objective" method (DTO) is used as an approach to provide a tool for decision support. This approach helps architects making decision. In addition, due to the DTO, all stakeholders in the field of construction can contribute to the programming phase. On the other hand, attention is directed toward the socio-cultural aspect which has been neglected by existing methods. This tool / software (SustainPro) has been experimented on four real projects in Iran. Experimental outcomes attest of the pertinence of the proposed approach

Abstract:

En conception d’avant projet, les impératifs de rapidité et de réduction des coûts sont à l’origine du recours quasi-systématique aux techniques d’optimisation numérique. La conception la plus performante est ici l’objectif principal recherché. Depuis quelques années, les chercheurs et les industriels s’intéressent à des méthodes de simulation intégrant les imprécisions inhérentes à la réalisation des produits manufacturés. L’objectif est alors d’étudier la robustesse des solutions vis-à-vis de la variabilité des paramètres du modèle. Les produits n’étant jamais le reflet exact de la conception optimale retenue, il s’avère aujourd’hui essentiel de coupler ces deux approches pour répondre également aux exigences de qualité. Les travaux présentés dans ce mémoire concernent la définition d’une stratégie d’optimisation robuste répondant à des objectifs multiples et adaptée au dimensionnement dynamique de systèmes mécaniques en phase d’avant projet. La méthodologie proposée s’appuie sur des techniques d’optimisation éprouvées et intègre les imprécisions via des méthodes de réanalyse exploitant des développements en série. Le choix de ces deux approches est justifié par l’utilisation commune des techniques de sensibilité, permettant ainsi des gains de temps. La méthodologie a été appliquée au dimensionnement fonctionnel d’une suspension de groupe motopropulseur (GMP). Cet ensemble mécanique présente en effet des contraintes de dimensionnement multiples et antagonistes associées à des variabilités d’une partie de ses constituants. Sur ce cas industriel, la méthodologie a permis de déterminer et de valider des solutions nouvelles garantissant une stabilité des performances
In preliminary projects, numerical optimization techniques allow to obtain efficient solutions rapidly and at lower cost. The aim of such tools is to search and obtain the best design. For a few years, methods of simulation integrating the inaccuracies inherent in the realization of the manufactured goods have been developed. The purpose is then to study the robustness of the solutions with respect to the variability of the parameters of the model. In order to improve the quality of the products it is now essential to take both efficiency and robustness into account. In this study we propose a new robust optimization strategy which allows to handle several objective functions for the improvement of dynamic behaviour of mechanical systems in the design step. The proposed methodology is based on multi-objective optimization method and takes parameters imprecision into account using second-order approximation. Coupling both those methods is justified by the common use of sensitivities. Then, an application on a powertrain mounting system has been performed using this tool. For this industrial test case, new robust and optimal designs have been obtained and validated

Ce travail permet de dégager les paramètres influant sur le bruit de phase et établit une méthode de conception permettant d'obtenir le minimum de bruit de phase dans les oscillateurs. Le premier chapitre donne un descriptif du fonctionnement du transistor bipolaire et identifie les avantages et inconvénients des différentes familles de TBH par rapport aux transistors à effet de champ afin de confirmer les potentialités du TBH pour les applications microondes. Le second chapitre est alors consacré à la présentation d'un modèle non-linéaire, non-quasi-statique et électro-thermique du TBH. Les différentes étapes permettant de l'obtenir, ainsi que sa validation à travers plusieurs mesures sont présentées.

Abstract:

Ce memoire est consacre a la conception optimale d'oscillateurs a bruit de phase minimum. Plusieurs techniques existent, a l'heure actuelle, pour apporter une reponse au probleme du bruit de phase au sein des oscillateurs libres utilisant des transistors microondes performants associes a des resonateurs dielectriques a fort coefficient de qualite. Toutefois, aucune methode ne permet d'atteindre le minimum de bruit a partir d'une architecture de circuit donnee. Notre travail s'inscrit donc dans le cadre de la recherche d'une methode de conception de tels dispositifs. Dans le but de degager les parametres influant sur le bruit de phase, nous avons choisi une structure d'oscillateur a transistor et resonateur dielectrique qui allie simplicite et performance. A partir d'un transistor adapte sur 50 et d'une cavite resonante donnes, nous avons determine les coefficients de couplage du resonateur avec le reste du circuit autorisant l'optimisation de la pente de susceptance ramenee en entree du circuit ou la maximisation du coefficient de qualite, parametres essentiels influant sur le bruit de phase. La premiere optimisation garantit cependant de meilleurs performances. De plus, un fonctionnement en puissance ajoutee maximale du transistor assure un transfert d'energie optimal entre les acces de la cavite. Enfin, deux dephaseurs, introduits de part et d'autre du resonateur couple, permettent un reglage final du circuit oscillateur afin d'obtenir le minimum de bruit. Ces differentes conclusions ont ete entierement validees par le biais de la simulation numerique et de l'experimentation. La realisation d'une maquette d'oscillateur sur table, fonctionnant a 9. 2 ghz et s'inscrivant dans le cadre du projet pharao finance par le cnes constitue l'aboutissement de ce travail.

Abstract:

Le projet HODISS dans le cadre duquel s'effectue nos travaux adresse la problématique de la synchronisation globale des systèmes complexes sur puce (System-on-Chip ou SOCs, par exemple un multiprocesseur monolithique). Les approches classiques de distribution d'horloges étant devenues de plus en plus obsolètes à cause de l'augmentation de la fréquence d'horloge, l'accroissement des temps de propagation, l'accroissement de la complexité des circuits et les incertitudes de fabrication, les concepteurs s’intéressent (pour contourner ces difficultés) à d'autres techniques basées entre autres sur les oscillateurs distribués. La difficulté majeure de cette dernière approche réside dans la capacité d’assurer le synchronisme global du système. Nous proposons un système d'horlogerie distribuée basé sur un réseau d’oscillateurs couplés en phase. Pour synchroniser ces oscillateurs, chacun d'eux est en fait une boucle à verrouillage de phase qui permet ainsi d'assurer un couplage en phase avec les oscillateurs des zones voisines. Nous analysons la stabilité de l'état synchrone dans des réseaux cartésiens identiques de boucles à verrouillage de phase entièrement numériques (ADPLLs). Sous certaines conditions, on montre que l'ensemble du réseau peut synchroniser à la fois en phase et en fréquence. Un aspect majeur de cette étude réside dans le fait que, en l'absence d'une horloge de référence absolue, le filtre de boucle dans chaque ADPLL est piloté par les fronts montants irréguliers de l'oscillateur local et, par conséquent, n'est pas régi par les mêmes équations d'état selon que l'horloge locale est avancée ou retardée par rapport au signal considéré comme référence. Sous des hypothèses simples, ces réseaux d'ADPLLs dits "auto-échantillonnés" peuvent être décrits comme des systèmes linéaires par morceaux dont la stabilité est notoirement difficile à établir. L'une des principales contributions que nous présentons est la définition de règles de conception simples qui doivent être satisfaites sur les coefficients de chaque filtre de boucle afin d'obtenir une synchronisation dans un réseau cartésien de taille quelconque. Les simulations transitoires indiquent que cette condition nécessaire de synchronisation peut également être suffisante pour une classe particulière d'ADPLLs "auto-échantillonnés"
The HODISS project, context in which this work is achieved, addresses the problem of global synchronization of complex systems-on-chip (SOCs, such as a monolithic multiprocessor). Since the traditional approaches of clock distribution are less used due to the increase of the clock frequency, increased delay, increased circuit complexity and uncertainties of manufacture, designers are interested (to circumvent these difficulties) to other techniques based among others on distributed synchronous clocks. The main difficulty of this latter approach is the ability to ensure the overall system synchronization. We propose a clock distribution system based on a network of phase-coupled oscillators. To synchronize these oscillators, each is in fact a phase-locked loop which allows to ensure a phase coupling with the nearest neighboring oscillators. We analyze the stability of the synchronized state in Cartesian networks of identical all-digital phase-locked loops (ADPLLs). Under certain conditions, we show that the entire network may synchronize both in phase and frequency. A key aspect of this study lies in the fact that, in the absence of an absolute reference clock, the loop-filter in each ADPLL is operated on the irregular rising edges of the local oscillator and consequently, does not use the same operands depending on whether the local clock is leading or lagging with respect to the signal considered as reference. Under simple assumptions, these networks of so-called “self-sampled” all-digital phase-locked-loops (SS-ADPLLs) can be described as piecewise-linear systems, the stability of which is notoriously difficult to establish. One of the main contributions presented here is the definition of simple design rules that must be satisfied by the coefficients of each loop-filter in order to achieve synchronization in a Cartesian network of arbitrary size. Transient simulations indicate that this necessary synchronization condition may also be sufficient for a specific class of SS-ADPLLs

Deux approches de cette technologie sont actuellement en développement, menant à l'installation au CERN de deux prototypes dont la construction devrait s'achever fin 2018. Le travail présenté dans cette thèse s’intègre dans le cadre du projet ProtoDUNE-DP, qui vise à prouver la faisabilité de la technologie dite « double-phase », c’est-à-dire utilisant de l'argon liquide et gazeux, pour les LArTPC de cette envergure. Deux signaux principaux sont attendus dans un tel détecteur, un signal de charges et un signal lumineux de scintillation. Le signal lumineux peut être utilisé dans le système de déclenchement d'acquisition des données, dans l’identification et éventuellement la réjection du signal dû aux muons cosmiques, et pour des mesures calorimétriques de précision. Des simulations préalables de ce signal sont donc nécessaires afin d'en comprendre les particularités et de développer des algorithmes d'identification. Cette thèse porte en particulier sur le développement de cette simulation et sur l’étude de la propagation des photons de scintillation au sein du détecteur. Les différents mécanismes de production de la lumière de scintillation, la simulation développée au cours de cette thèse et les études réalisées sur la propagation de la lumière de scintillation dans ProtoDUNE-DP seront présentés. Ces simulations ont également pu être comparées aux données recueillies avec un pré-prototype double-phase installé au CERN en 2017, afin de tester la validité de la simulation et d’en améliorer les différents paramètres
DUNE is a future long-baseline neutrino experiment designed to determine, among others, the neutrino mass hierarchy and to measure the CP violation phase that enters the neutrino oscillation process. This project is based on a 1300 km long high intensity neutrino beam and a massive detector containing more than 40 kilotons of liquid argon using the liquid argon time projection chamber technology (LArTPC). Two approaches of this technology are currently under development, leading to the construction of two prototypes to be in place at the end of 2018 at CERN. The work of this thesis is part of the ProtoDUNE-DP project, which aims at probing the capabilities of the so-called “dual-phase” technology, that uses both gaseous and liquid argon, for a large-scale detector. Two kind of signals, a charge signal and a scintillation light signal, are expected in a LArTPC. The light signal can be used as a trigger, for the identification and rejection of the cosmic background, and for precise calorimetric measurements. Prior simulations of this signal are needed in order to improve our understanding of the scintillation light signal and to develop the identification algorithms. This work addresses the development of this simulation and the study of the scintillation photon behavior in the liquid argon detector. The different scintillation light production mechanisms, the developed simulation and the different studies on the light propagation in ProtoDUNE-DP are presented. These simulations have also been compared with light data taken at CERN in 2017 with a first demonstrator, in order to validate and tune the simulation

Abstract:

Ce document contient les objectifs, le cheminement suivi et les résultats obtenus d'un projet visant à identifier le nombre d'onde sur différents types de plaques représentatives de ce qui est utilisé en aéronautique. Dans une première partie, on y définit les enjeux du sujet, liés au domaine aéronautique et le contexte dans lequel ce projet se déroule. A la suite de quoi, est exposée la revue de l'état de l'art sur les méthodes existantes de mesure du nombre d'onde. Le projet en lui-même est ensuite défini avec un objectif principal fixe qui est de mesurer le nombre d'onde d'une plaque à partir de mesures vibratoires. Pour cela deux méthodes seront utilisées; la méthode de différence de phase permettant d'effectuer la mesure sur les plaques simples ou composites et la méthode du passage dans le domaine des nombres d'onde permettant cette même mesure sur des plaques plus complexes (plaque épaisse ou raidie par exemple). Pour chaque méthode, un cheminement équivalent est utilisé. Dans un premier temps, on développe et implémente la méthode choisie de manière basique, puis on réalise l'étude paramétrique permettant de connaitre les conditions optimales de fonctionnement des deux méthodes, enfin une validation expérimentale est réalisée. Dans ce document, les deux méthodes seront aussi comparées pour en déduire dans quelles conditions il faut utiliser l'une ou l'autre des méthodes. La méthode de la différence de phase donne de bons résultats dans le cas de plaques simples et composites si on est capable d'exciter suffisamment toutes la gamme de fréquence. La méthode du passage dans le domaine des nombres d'onde quant à elle est apte à mesurer le nombre d'onde sur tous types de plaques et dans toutes les directions si la zone de mesure est suffisamment grande.

Abstract:

Le projet HODISS dans le cadre duquel s'effectue nos travaux adresse la problématique de la synchronisation globale des systèmes complexes sur puce (System-on-Chip ou SOCs, par exemple un multiprocesseur monolithique). Les approches classiques de distribution d'horloges étant devenues de plus en plus obsolètes à cause de l'augmentation de la fréquence d'horloge, l'accroissement des temps de propagation, l'accroissement de la complexité des circuits et les incertitudes de fabrication, les concepteurs s'intéressent (pour contourner ces difficultés) à d'autres techniques basées entre autres sur les oscillateurs distribués. La difficulté majeure de cette dernière approche réside dans la capacité d'assurer le synchronisme global du système. Nous proposons un système d'horlogerie distribuée basé sur un réseau d'oscillateurs couplés en phase. Pour synchroniser ces oscillateurs, chacun d'eux est en fait une boucle à verrouillage de phase qui permet ainsi d'assurer un couplage en phase avec les oscillateurs des zones voisines. Nous analysons la stabilité de l'état synchrone dans des réseaux cartésiens identiques de boucles à verrouillage de phase entièrement numériques (ADPLLs). Sous certaines conditions, on montre que l'ensemble du réseau peut synchroniser à la fois en phase et en fréquence. Un aspect majeur de cette étude réside dans le fait que, en l'absence d'une horloge de référence absolue, le filtre de boucle dans chaque ADPLL est piloté par les fronts montants irréguliers de l'oscillateur local et, par conséquent, n'est pas régi par les mêmes équations d'état selon que l'horloge locale est avancée ou retardée par rapport au signal considéré comme référence. Sous des hypothèses simples, ces réseaux d'ADPLLs dits "auto-échantillonnés" peuvent être décrits comme des systèmes linéaires par morceaux dont la stabilité est notoirement difficile à établir. L'une des principales contributions que nous présentons est la définition de règles de conception simples qui doivent être satisfaites sur les coefficients de chaque filtre de boucle afin d'obtenir une synchronisation dans un réseau cartésien de taille quelconque. Les simulations transitoires indiquent que cette condition nécessaire de synchronisation peut également être suffisante pour une classe particulière d'ADPLLs "auto-échantillonnés".

Abstract:

Construction projects comprise holistic and organic processes of the conceptual, detailed engineering, construction and start-up phases. The conceptual phase is the most critical phase in a project's life-cycle where the main strategic decisions are made. The success of other phases depends upon the decisions made during the conceptual phase. Although the conceptual phase presents the greatest opportunity for productivity improvement during the construction phase, it has been given relatively little attention. The main aim of this research was to establish the conceptual phase tasks and associated best practices for major projects that ensure good site productivity through decisions made in the conceptual phase. The aim was realised through the following five objectives: define tasks performed in the conceptual phase; rank the impact of conceptual phase tasks on site productivity; determine the impact of conceptual phase tasks on productivity in terms the main site resources of time, labour, plant, material and finance; establish the sequence with which tasks are performed in the conceptual phase; and establish Best Practices associated with each of the conceptual phase tasks. The research findings were based upon literature, an industry-wide postal questionnaire survey and case studies. The survey comprised a substantial twenty-page questionnaire containing 184 questions. The questionnaire was posted to 144 companies including clients, consultants, contractors and financial institutions throughout the European Union. A return of 37 per cent was achieved. The industry-wide survey was then followed by detailed case studies of six projects: a power plant; a chemical plant; a sewerage treatment plant; an offshore-structure; a motor way; and, a substantial building project. These case studies underpinned the survey and specific differences and similarities were highlighted among the six projects and the processes adopted during the conceptual stages. The industry-wide survey and complementary case studies formed the basis of recommendations for conceptual phase tasks and associated best practices achieving enhanced site productivity. It was concluded that the conceptual phase of construction projects comprised ten tasks: Consents and Permits; Project Definition; Financial Strategy; Project Planning; Contract Strategy; Project Management Organisation; Construction Philosophy; Procurement Strategy; Design of Temporary Works; and, Design of Permanent Structures. Eighty-one best practices relating to the conceptual phase were accepted by the respondents. These best practices, when adopted in the conceptual phase, should held to enhance site productivity.

Abstract:

The capture and beneficial application of learning from past experiences in projects has been an area of interest and debate for many years. The implementation of lessons learnt is commonly acknowledged as difficult. Existing studies point to the deficiencies in current practice but few propose practical approaches to improve the situation. A key barrier to learning in projects is the time-critical nature of most projects which makes the creation of time and space to learn and then apply the resultant learning problematic. Other inhibitors include the variety and temporality of project teams, the geographical spread of many projects and client pressures to reduce costs. The aim of this research was to improve project learning processes in multi-phase project environments through the identification and application of relevant organizational learning and knowledge management theories. The research was based on a single company longitudinal case study in an infrastructure support services organization. An event-based approach to project lessons was developed which focuses on benefits realisation and measurement. The processes employed overcome some of the key barriers to the effective capture of lessons learnt and their subsequent implementation i.e. shortage of time, different learning styles of individuals, lack of effective capture mechanisms, poor articulation of benefits realisation, lack of management sponsorship. A model was also developed which acts as a multi-faceted lens which aids the understanding of the dynamics of project-based learning. The model was tested through a series of workshops. In order to assist the roll-out of the new approach across the case study organisation and outline implementation guide that has been developed. The approach can also be promoted externally to improve project management practice across the wider construction industry. In addition, the study also revealed that event-based enactment of complex/abstract theories can be used as a tool to create improved praxis by overcoming the need to explain the theories to the actors involved. The main contribution to research is the development of a new approach which extends existing theory in the areas of learning, knowledge management and boundary objects in multi-phase project contexts. It achieves this through the synergistic use of the theories employed which support the development of reflective practitioners with the skills to engender a 'learning how to learn' culture within project-based environments. Further testing of ongoing benefits monitoring and establishing causality is needed. Overall, the methodology developed is highly adaptable and can be used by others in different organizational contexts to improve organizational learning, business performance, client satisfaction and wider stakeholder outcomes.

Dissertação de Mestrado em Estratégia
A Estratégia ocupa um papel cada vez mais significativo no seio das organizações. A sua relevância deve-se ao facto de que num mundo globalizado, e em constante competição, o delineamento de objetivos precisos, o reconhecimento do ambiente, e o planeamento minucioso tornam-se exercícios quase fundamentais na procura do sucesso. Mas se por um lado sabemos que a Estratégia é uma ciência da era moderna, pensada de acordo com o mundo atual, designadamente pela sua conceção empresarial, também facilmente reconhecemos que ela pode ser aplicada a outras eras, e às mais diversas realidades. Este estudo dedica-se a apresentar a teoria da estratégia aplicada a um contexto histórico específico, onde o objetivo se apresenta num formato geográfico de relevância geopolítica. Parte do argumento de que os Estados Unidos constitui uma das maiores potências da nossa era, sendo que este estatuto é fruto de um processo estratégico que se iniciou após a sua fundação e que passou por três grandes fases até apresentar os resultados atuais: uma fase que dedicou à construção do território; uma segunda relativa à projeção dos objetivos geopolíticos a nível continental; e uma terceira que projeta os interesses dos americanos para todo o mundo. A presente dissertação trata de analisar a primeira fase deste projeto, e do respetivo processo de construção territorial. De uma faixa litoral encostada ao Atlântico, foi possível chegar à costa oposta do Pacífico absorvendo o território interior, em várias etapas, e posteriormente formalizando a sua divisão administrativa, num projeto com uma longevidade de pouco mais de cem anos. Aqui faremos o levantamento de todos os elementos essenciais à prossecução desses objetivos, compreendendo o papel que esta fase tem no desenvolvimento do projeto geopolítico global e, consequentemente, o contributo para o atual estatuto dos EUA na política internacional. Demonstra-se que desde o início que existia um desejo expansivo, e uma iniciativa de progredir para oeste. A intenção de conquistar todo o território até ao Pacífico revelou-se irrefutável a partir do momento que os americanos se mostraram a maior potência regional. Tratou-se de uma expansão estrategicamente projetada e planeada, embora dependente de conjunturas benéficas. Conclui-se que esta fase desempenhou um grande papel no grande projeto geopolítico norte-americano, dado que estabeleceu as bases das fases seguintes, garantindo o poder nas diversas formas para evoluir nos objetivos, e no alcance geográfico dos mesmos.
Strategy occupies an increasingly significant role within organizations. Its relevance is due to the fact that in a globalized world, and in constant competition, the design of precise objectives, the recognition of the environment, and the thorough planning become almost fundamental exercises in the pursuit of success. But if on the one hand we know that the strategy is a science of the modern age, conceived according to the current world, namely by its entrepreneurial conception, we also easily acknowledge that it can be applied to other eras, and to the most diverse realities. This study is dedicated to presenting the strategy theory applied to a specific historical context, where the objective is presented in a geographic format of geopolitical relevance. Part of the argument that the United States constitutes one of the greatest powers of our age, and this statute is the result of a strategic process that began after its founding and which went through three major phases to present the current results: a phase dedicated to the construction of the Territory; A second on the projection of geopolitical objectives at continental level; And a third that projects the interests of Americans to the whole world. This dissertation is about analyzing the first phase of this project, and the respective process of territorial construction. From a coastal strip leaning against the Atlantic, it was possible to reach the opposite coast of the Pacific absorbing the interior territory, in several stages, and subsequently formalizing its administrative division, in a project with a longevity of just over a hundred years. Here we will survey all the essential elements to pursue these objectives, understanding the role that this phase has in the development of the global geopolitical project and, consequently, the contribution to the current U.S. statute in the policy International. It is shown that from the outset there was an expansive desire, and an initiative to progress to the West. The intention to conquer the entire territory to the Pacific proved to be irrefutable from the moment that the Americans showed the greatest regional power. This was a strategically designed and planned expansion, albeit dependent on beneficial conjunctures. It is concluded that this phase played a major role in the Great North American geopolitical project, since it established the bases of the following phases, guaranteeing power in the various ways to evolve in the objectives, and in the geographic reach of them.

Abstract:

Introduction: A trend for organisations to change from single to multiple project management has been observed over the last couple of decades. Organizations shifted their focus from single project management towards the simultaneous management of the whole set of projects as one entity – project portfolio. New multi-project settings require a new management approach and practices to successfully manage a portfolio. A common practice in organizations is to evaluate projects after they had been carried out. At that point not much can be done and it is impossible to improve performance and prevent failure. Hence, problems that occur in projects’ implementation phase remain unsolved and even unidentified. Constant control, review and monitoring of projects’ performance in the implementation phase could lead to the problematic portfolio areas being spotted and timely management decisions being made in order to improve the overall portfolio performance.

Problem: How do organisations manage projects within a portfolio that perform poorly in the implementation phase?

Purpose: The purpose of this thesis is: to describe to what extent and in what ways organizations control, review and monitor project performances in the implementation phase; to identify if organisations use any methods, tools or techniques in order to spot projects that perform poorly according to their expectations; and to discover what happens to the poorly performing projects in the implementation phase after they were identified.

Method: An electronic qualitative questionnaire had been constructed and sent out to the 46 sampled Swedish companies currently running project portfolios. 115 most suitable respondents had been chosen to answer the survey.

Frame of Reference: Theoretical framework is built on the literature within project portfolio management field, mostly concerning control, review and monitoring of projects of projects’ performance within their implementation phase; practices used to manage poorly performing projects as well as the value of organizational learning.

Conclusion: The research results show that even though majority of the studied organizations are aware and striving towards efficient project portfolio control, review and monitoring, a lot of space for improvement still remains. Results reveal that organizations are trying to keep track of projects’ performance within a portfolio, however, very few poorly performing are identified. Moreover, the management practices for underperforming projects are still very limited if not non-existent.

Abstract:

Title The initial phase of cancer care- an action research projectRationale for the study Anecdotal evidence suggested that patients receiving treatment within a Cancer Unit were not receiving equitable care. Some patients reported being told their diagnosis in an empathetic manner, whilstothers reported consultants being brutal and/or uninterested. In addition, it appeared that patients were given variable levels of support and information during their initial phase of cancer care. Aims of the study The purpose of the study was to explore whether the information and support offered to cancer patients in the initial phase of care was sufficient and appropriate to their needs. It was further hoped that the findings of the study could be utilised to change services in a patient centred way. Methodology A qualitative study divided into three stages. Firstly, eighteen non-participant observations of doctor/patient consultations were carried out at the time when patients were told they had a diagnosis of cancer and given information relating to their proposed treatment. The purpose of this was to ascertain what actually happened in practice. The data resulting from this stage of the study enabled an understanding of the problem in context and facilitated the development of an interview schedule, which formed the basis of the second stage of fieldwork. Stage two consisted of thirty-three semi structured, tape recorded patient interviews. These were carried out 3- 4 months following diagnosis. The third stage of the study consisted of interviews and focus groups with consultants, clinical nurse specialists and senior managers, the purpose of which was to explore their views regarding the results of the patient interviews and perceptions of theimplementation of change in clinical practice. The approach taken to structure the data collection was based on grounded theory (Glaser and Strauss, 1967). Findings Many of the issues raised in the patient interviews were consistentwith the literature i.e. patients experience a wide variety of emotions when told they have cancer. The vast majority of patients hear little after the word "cancer", it is therefore important to repeat information and ensure patients have access to ongoing support. Patients also value being told the truth, continuity of information and doctors showing that they care. They appear more satisfied with their care where an effective multidisciplinary team exists. However, patients inthe Cancer Unit where the study was conducted did not receive equitable care, particularly in relation to the amount and type of information and support offered to them in the initial phase of cancer care. The third stage of the study explored consultants', clinical nurse specialists' and senior managers' views relating to the findings from stages one and two of the study. The health care professionals did not exhibit surprise at any of the findings but were keen to explore them further. Views relating to the implementation of change within cancer care were also explored in this stage of the study and their comments were largely consistent with the literature on change management. Innovations in practice A number of changes have been made to clinical practice, including, improved multidisciplinary team working, developing multidisciplinary documentation and developing site specific cancer pathways which identify the patients journey from the point of referral through to follow up or palliation. These pathways help patients know what to expect at each stage of their disease journey and ensure patients receive equitable care, because the pathways act as guidelines for professionals outlining good practice at each stage of the journey. All of the developments initiated to date are aimed at improving the patient experience and staff satisfaction relating to the service they provide.

Abstract:

The construction sector has been struggling with low productivity issues during the last decades, mainly due to relatively low Research & Development investments compared to other industries, old-fashioned practices, and a fragmented market structure with Clients, Designers and Contractors. The construction sector urges a digitalization revolution in order to overcome the aforementioned old-fashioned practices, but this digital revolution should go along with adequate methodologies that allow the digitalization to achieve its full potential. The work presented in this thesis aims to improve the efficiency of the construction sector by having a look on more collaborative approaches between Clients, Designers and Contractors in Construction Projects. The collaborative approach researched in this thesis is the Integrated Concurrent Engineering methodology, which covers aspects of Project Management, Organization, Communication and Leadership, exploiting the digitalization capabilities that nowadays’ Technology offers. This thesis develops a theoretical framework for Integrated Concurrent Engineering in Construction Projects, with the aim to enhance their efficiency. The theoretical framework is based in literature research as well as experiences from project managers in the construction sector. The result of this study includes guidelines and recommendations on how to effectively implement the principles of Integrated Concurrent Engineering. The guidelines are applicable for Clients, Designers and Contractors, and can be seen as a tool for the Project Management Team to improve construction project’s efficiency, especially in the design phase.

Abstract:

Project management is today a current and highly discussed area. How projects within the construction industry are managed has not changed significantly during the last decades. The construction market, the number of different actors and the way that projects are procured today has however changed. This has led to a gap between the managerial view on how construction projects should be conducted today and how they actually are executed. This is reason enough to question this conservative industry and look into what possibilities there might be in the future. The Agile project management approach evolved from the software industry where it has grown and developed through empirical progress. It is suited for large complex projects where it is difficult to specify the product in advance. It is today used in different industries but mostly in the software business where the customer detects their needs through means of repeated tests and improvements to a prototype. This thesis has researched what opportunities there might be in implementing the Agile project management approach in the design phase of construction projects. The major advantages found with implementing the Agile approach is an increase in the client’s involvement. The Agile approach almost forces the client to increase their participation in the project compared to the situation today. It can also decrease uncertainty and improve risk management. By the use of time management and specific meetings it will also be beneficial for keeping track of the project’s progression and status.

Abstract:

With the current trend towards empowered teams, hierarchical company structures are increasingly being replaced by team-based ones. As a result, a shift in the classic understanding of leadership is needed and research on leadership in project management is increasing. Two major concepts have developed in recent years: shared and vertical leadership styles. This thesis reports on the development of a new Model of leadership styles that considers the effect of project types and the project life cycle phases on leadership style (vertical versus shared leadership), and how an appropriate balance between the two styles influences the likelihood of project management success. A web-based questionnaire yielded 313 complete responses and the data was analysed using hypothesis testing. Based on this empirical work and relevant literature, a novel Model is proposed. The Model explains how project types and life cycle phases influence the appropriateness of different leadership styles, and it guides the practitioner to selecting appropriate leadership styles for specific situations. Recommendations for furthering the model are discussed.

The present investigation looks at management consulting engagements through the project management lens, and explores what practitioners do in the initial stages of their projects. In the understanding that the front-end of the project is a very critical and important stage, this text begins by examining the literature on management consulting and on the definitional phase of projects, and demonstrates that the situations encountered in both domains are quite similar. For this reason, this study explores the project management practices that Swedish management consultants employ in the initial phases of the consulting projects. Particularly, it focuses on the practices that reconcile possible gaps in perspectives and expectations that often exist between client and consultant when this relationship is being formed. The study had an inductive character and is cross-sectional in terms of time-horizon, focusing on the previous experiences of management consultants. In collecting the data, a survey strategy was usedwith semi-structured interviews involving nine Swedish management consultants from eight different consultancies. The process of analysis implied the use of template analysis, which provided researchers with enough flexibility to code, categorize, and interpret necessary findings. The results show that consultants favor practices that revolve around communication and interaction with the client, including interviews, workshops, and meetings, among others. In addition, they stress the importance of the use of documentation in order to reach an agreement on what the project is about. Moreover, these practices were often clearly connected to the issues that they, as project managers, must resolve at the front-end of projects. Interestingly, the results indicate that these challenges, identified by the management consultants, mostly match the ones identified in the project management literature. There is indeed a connection between project management practices and management consulting, from which both fields can benefit.

Abstract:

Dans un contexte de mondialisation accrue et d’apparition de nouvelles forces issues des marchés dits émergents, les firmes multinationales (FMNs) ont développé des stratégies d’innovation novatrices. C’est en particulier au niveau des processus d’innovation que s’est opérée une des transformations les plus importantes. Elles doivent aujourd’hui faire face à une multiplication des sources d’innovation en matière de recherche et de développement (phase amont du processus d’innovation). Dans le même temps, les FMNs doivent aussi saisir toutes les opportunités de commercialisation et d’appropriation des innovations à l’échelle mondiale (phase aval) à travers leur réseau de filiales. La phase amont de ce processus est par nature complexe et itérative du fait de l’intégration de connaissances multiples et dispersées géographiquement. Cette particularité du processus d’innovation des FMNs se traduit par un encastrement de l’innovation à un niveau dit local. Cet encastrement rend alors la phase aval elle aussi très complexe, ne se limitant pas à une démarche uniquement marketing. Jusqu’ici, la phase aval a été conceptualisée de manière centralisée et désincarnée d’un point de vue organisationnel à travers les concepts de diffusion et de transfert. Ces approches ne permettent pas de rendre compte des modifications du processus d’innovation des FMNs et de comprendre des phénomènes empiriques tels que par exemple l’innovation inversée ou l’innovation dite frugale. C’est à travers l’étude d’un cas unique, une grande FMN française, que nous avons exploré et analysé cette phase aval. Grâce à ce travail, nous avons défini un cadre intégrateur: le déploiement des innovations. C’est un processus qui comprend l’enchaînement des commercialisations d’une innovation par des filiales situées dans des contextes locaux différenciés et nécessitant à chaque fois son adaptation. Ce déploiement est ainsi spatial, car l’innovation est exploitée dans différentes géographies, et temporel, car les adaptations peuvent s’étendre sur une durée. Nos principaux résultats s’articulent autour de trois niveaux d’analyses. Nous étudions d'abord les projets et communautés de déploiement pour mieux comprendre l’articulation du déploiement entre l’organisation et les individus. Ensuite, nous analysons le déploiement au niveau des individus et des compétences en défendant l’idée que la FMN doit aujourd’hui penser une fonction "chef de projet déploiement" en son sein. Enfin, nous nous positionnons au niveau de la stratégie d’innovation des FMNs en mettant en perspective le rôle du siège et celui des filiales
In a context of increased globalization and the rise of new forces from so-called emerging markets, multinational corporations (MNCs) have developed new innovation strategies. In particular, one of the most considerable transformations has taken place in their innovation processes. MNCs must now face a multiplication of sources of innovation in terms of research and development (upstream phase of the innovation process). They also have to seize all the opportunities for commercialization and appropriation of innovations on a global scale (downstream phase) through their subsidiaries’ network. The upstream phase of this process is complex and iterative in nature because of the integration of multiple and geographically dispersed knowledge. The result of this peculiarity of the MNC’s innovation process is the embededness of innovation at a local level. This embedding makes the downstream phase also complex, not just a marketing process. Up to now the downstream phase has been centrally conceptualized and disembodied from an organizational point of view through the concepts of diffusion and transfer. These approaches do not capture changes in the MNC’s innovation process and do not succed to frame empirical phenomena such as reverse innovation or the specialisation of subsidiaries in certain phases of the innovation process. It is through the study of a unique case, a large French MNC that we explored and analyzed this downstream phase. Thanks to this work, we have defined an integrative framework: the deployment of innovations. It is a process that includes sequencing of the commercialization of an innovation by subsidiaries located in differentiated local contexts and requiring each time to be adapted. This deployment is thus both spatial, because the innovation is utilized in different geographies, and temporal, because adaptations may take place over time. Deployment is therefore a concept that has a descriptive scope (understanding the downstream phase) but can also be utilized by companies (the means to be implemented to optimize this downstream phase). Our main results are based on three levels of analysis. First, at the level of deployment projects and communities to better understand the articulation of deployment between the organization and individuals. Then we put the stress on the skills needed for deployment with the idea that the MNCs must now think of a project deployment function. Finally, on the innovation strategy of MNCs, where we put the role of headquarter and subsidiaries in perspective

Abstract:

DevOps is an ill-defined but trending approach to software development. Many companies are seduced by its promises of reduced costs and risks. DevOps life-cycle is often represented as a continuous everything, but very little is said about how to get the ball rolling. This report examines how DevOps definitions are represented in the initiation of Agile projects. By interviewing developers and mapping their project initiation activities in a DevOps context, a set of guidelines was formed. Continuous Integration and Deployment were found most prominent DevOps attributes from a developer’s perspective. The operational responsibility is skewed toward maintenance, with low interest in further adjustment.

Abstract:

Alors que les principales activités d’un chef de projet s’effectuent à travers le processus de communication, on observe que de nombreux projets font l'objet de retards, dérives ou défauts de spécifications. Excès de mesures pour prévenir le risque ou gestion déficiente de la communication laissant trop de place à l’incertitude ? La Théorie de la Réduction de l’Incertitude développée par Berger et Calabrese (1975) dans le champ de la communication ne permet pas de totalement saisir comment un chef de projet dissipe l’incertitude existante entre les acteurs. En revisitant un projet opérationnel dans le cadre d’une recherche-action, nous nous employons à identifier comment incertitude et communication s’influencent et se structurent mutuellement. Nous avons convoqué l’approche constructiviste et la théorie de l’acteur-réseau de Callon et Latour pour accéder au sens de cette relation circulaire. Nous avançons les hypothèses selon lesquelles : - L’incertitude est un actant qui intervient dans la construction du réseau (au sens de Bruno Latour (2007) « ce qui est tracé par les traductions »).- Le processus de communication diffère suivant la nature de l’incertitude rencontrée ou ressentie. - Le processus de communication performe et scelle les relations en les rendant si coûteuses à défaire et si économiques à maintenir, qu’elles deviennent irréversibles. L’approche communicationnelle de l’incertitude mettra en évidence plusieurs caractéristiques de cet actant, comme sa capacité à peupler un « réseau de manques », la façon dont le réseau se hiérarchise pour faire sens, la description du processus d’estimation continue dont il fait l’objet (l’Incertus). Si nous concevons l’incertitude comme l’attribut d’un phénomène alors la « communication-incertitude » fabrique le sens en même temps qu’elle détermine la valeur de cet attribut. En positionnant l’incertitude comme un phénomène socialement construit, nous présentons un modèle constructiviste de « communication-incertitude » où l’observateur est un acteur intentionnel limité par des contraintes (Boudon, 2009) et proposons de distinguer la nature de l’incertitude suivant une typologie : l’incertitude de variabilité (inhérente à la variabilité des choses), l’incertitude épistémique ambiguë ou non (due à l’imperfection de nos connaissances) et l’incertitude d'échelle (en rapport avec l’imperfection de nos modèles de représentations). Dans ce mouvement vers l’irréversibilité, les processus de communication participent au remplacement des médiateurs (qui transforment, redonnent du sens, font faire des choses inattendues) par des intermédiaires (qui transmettent, transfèrent sans modifier) et les actants les plus réversibles sont évacués vers la périphérie du réseau
While the main activities of a project manager are done through the communication process, it is observed that many projects are subject to delays, excesses or defects specifications. Excess of measurements to prevent the risk ? Defective management of the communication which leaves too much place to uncertainty ? The Theory of Uncertainty Reduction developed by Berger and Calabrese (1975) in the field of communication does not fully understand how a project dissipates the existing uncertainty between actors. By revisiting an operational project within the framework of action research, we strive to identify how uncertainty and communication influence and form themselves mutually. We used the constructivist approach and the actor-network theory of Callon and Latour to reach the meaning of this circular relationship. We advance the following hypotheses: - Uncertainty is a nonhuman actor involved in the construction of the network (as defined by Bruno Latour (2007) "which is drawn by translations"). - The communication process differs according to the nature of the uncertainty encountered or felt. - The communication process performs and seals relationships by making them so expensive to undo and so economic to maintain, that they become irreversible. The communicational approach of the uncertainty will highlight several features of this nonhuman actor, as its ability to populate a "network of gaps", the way the network ranks into a hierarchy to make sense, the description of the continuous process of estimation (the Incertus). If we conceive uncertainty as an attribute of a phenomenon, then "communication-uncertainty" makes sense at the same time it determines the value of this attribute. By positioning uncertainty as a socially constructed phenomenon, we present a constructivist model of "communication-uncertainty" where the observer is an intentional actor limited by constraints (Boudon, 2009). We propose to distinguish the nature of uncertainty following a typology: the variability uncertainty (inherent variability of things), the epistemic uncertainty ambiguous or not (due to the imperfection of our knowledge) and the scale uncertainty (in touch with the imperfection of our models of representations). In this movement towards irreversibility, the communication processes involved in replacing mediators (which transform, give meaning, make unexpected things do) by intermediaries (which transmit, transfer without changing) and the most reversible nonhumans actors are evacuated to the network edge

Abstract:

This thesis presents experimental studies of gas phasemolecular relaxation after excitation with synchrotron photonsin the 15-35 eV and in the 70-350 eV regions.

In the 15-35 eV region, molecular relaxation by neutraldissociation processes and non

Franck-Condon effects in N2 and O2 molecules have beenstudied by means of dispersed fluorescence and photoelectronspectroscopy experimental techniques, respectively. From thedispersed fluorescence data, excitation functions for themeasured atomic fluorescence spectra have been obtained. Fromthe recorded photoelectron spectra vibrational branching ratioshave been produced. The results obtained reveal that Rydbergseries and singly and doubly excited valence states of theappropriate symmetry energetically accessible in the studiedregion and interactions between themaccount for most of theobserved effects in these two type of experiments.

In the 70-350 eV range, molecular relaxation processesresulting in fragmentation of CD4 and SF6 after absorption ofsynchrotron light have been studied by energy resolved electronion coincidence technique using a multicoincidence experimentalstation developed by our group during the last five years forsuch type of experiments. The coincidence measurements yieldedmass spectra from which information about the kinematics of thedetected fragments has been deduced by means of Monte Carlosimulations of the experimental peak shapes. The obtainedresults show completely different dissociation patternsdepending on the molecular electronic states studied. Thesepatterns reflect the bonding properties of the excited orbitalsand they permit the description and in some cases theidentification of the different molecular relaxation pathwaysobserved. The achievements presented in this thesis exemplifythe potential of the multicoincidence station used in thereported experiments.

Abstract:

Nowadays, creativity is crucial to implement for the success of companies. Meanwhile, directivity seems to have a very negative reputation in the first sight. The objective of this paper is to identify and present a situation of creativity during the implementation phase of a project where directivity is used. This study consists of two phases. The first one is the ambition to create a primary model based on the present theories which are namely creativity, implementation phase and directivity. The second phase then aspires to draw the potential connections with the help of a qualitative study led on five different projects managers. This should help refine the primary model which will also make it easier to understand such complex notion.

Abstract:

Project management is today a current and highly discussed area. How projects within the construction industry are managed has not changed significantly during the last decades. The construction market, the amount of different actors and the way that projects are procured today has however changed. This has led to a gap between the managerial view on how construction projects should be conducted today and how they actually are executed. This is reason enough to question this conservative industry and look into what possibilities there might be in the future. The Agile project management approach is evolved from the software industry where it has grown and developed through empirical progress. It is suited for large complex projects where it is difficult to specify the product in advance. It is today used in different industries but mostly in the software business where the customer detects their needs through means of repeated tests and improvements to a prototype. This thesis has researched what opportunities there might be in implementing the Agile project management approach in the design phase of construction projects. The major advantages found with implementing the Agile approach is an increase in the client’s involvement. The Agile approach almost forces the client to increase their participation in the project compared to the situation today. It can also decrease the uncertainty and improve risk management. By the use of time management and specific meetings it will also be beneficial for keeping track of the project’s progression and status.
Projektledning är idag ett högaktuellt ämne diskuteras intensivt. Hur projekt inom byggbranschen styrs och leds har inte förändrats nämnvärt under de senaste decennierna. Byggmarknaden, mängden av olika aktörer och hur att projekten upphandlas dag har dock förändrats. Detta har lett till ett spricka mellan ledarskapssynen på hur byggprojekt skall utföras idag och hur de faktiskt genomförs. Detta är skäl nog att ifrågasätta denna konservativa bransch och titta närmre på vilka möjligheter det kan finnas i framtiden. Den Agila projektledningsmetoden har utvecklats inom mjukvarubranschen där den har vuxit och förbättrats genom empiriska framsteg. Den är lämpad för stora komplexa projekt där det är svårt att ange och definiera produkten i förväg. Den används idag i olika branscher, men främst i mjukvaruindustrin där kunden upptäcker sina behov med hjälp av upprepade tester och förbättringar av en prototyp. Denna avhandling har undersökt vilka möjligheter det kan finnas i att använda Agila projektledningsmetoder under projekteringsfasen i byggprojekt. De största fördelarna som finns med att använda den Agila metoden är en ökning av kundens engagemang och involvering i projekten. Den Agila metoden tvingar nästan kunden att öka deras deltagande i projektet jämfört med hur situationen ser ut idag. Det kan också leda till minskad osäkerhet och förbättrad riskhantering. Genom användning av ”time management” och särskilda möten kommer de Agila metoderna också att vara till nytta för att hålla reda på projektets framåtskridande och status.

Abstract:

The phrasal verb is a unique type of verb phrase that consists of a main verb, usually of only one or two syllables, followed by a particle, that works as a single semantic unit. Such meaning, however, is characteristically expressed in idomatic terms, which poses a formidable problem for students of English as a second language. To be understood, this meaning must be figuratively interpreted as well as literally translated.

Abstract:

Despite their recognized significance for project success and innovation, the management of the early project phases is still an under-researched area in project management. For organizations to secure a continuous stream of innovation, the utilization of capabilities is crucial for managing the early phases of R&D projects. The purpose of this dissertation is to advance the understanding of the management of the early project phases in hypercompetitive environments. The thesis addresses the research question of how organizations manage the early project phases of R&D in hypercompetitive environments for frequent innovation by taking a dynamic capabilities perspective. The first conceptual study reviews the literature covering organizational change in hypercompetitive environments with a focus on projects as the vehicle to create the necessary flexibility. The study found that organizational aspects and capabilities have to go hand in hand as enabler and facilitator for a successful emergent change process. The second qualitative study investigates how organizations organize the early project phases of R&D in the pharmaceutical industry for an outcome of frequent innovation. The findings show that an optimization of combinative capabilities that balances dynamic, project and multi-project capabilities can be used as a powerful leverage to boost the outcome of frequent innovation. The third study investigates the philosophical stances and related methodologies used within the last 15 years of project management research at the example of IRNOP conferences. The findings show that ontological subjectivism and epistemological interpretivism are dominating. Moreover, case studies and qualitative methods were the most common methods, whereas mixed method studies were lacking despite their value for developing an increasingly complex research field. The final mixed method study explores how absorptive, innovative and adaptive capabilities within the early phases of pharmaceutical R&D affect project and portfolio performance. Based on the results of quantitative study, the set of capabilities has an overall effect on the set of performance outcomes and thus confirms the results of the qualitative study that a distinct capability mix is needed in the pharmaceutical R&D process. To conclude, the dissertation has comprehensively explored the management of the early project phases through four studies and by applying a multitude of methodologies.
