Texto completo da fonteThe basis question of this thesis is : why and how investments in manufacturing technologies considered as vital for competitiveness and long term profitability of the firms can be also judged not profitable faced to financial criteria of the traditional theory of investment ? The study of advanced manufacturing technologies allows us to bring to light a strategic benefits, called tangible and intangible benefits that financial criteria can't take into account. The aim of this work is to understand the origin and the nature of this benefits, and to see how we can integrated them into the decision to invest. For that, we suggest a new and global method to assess all the strategic effects of the flexible technologies. Tree stages constitute this method. The first stage concern the definition of the objectives of performance assigned to technological investment. The second and the third stage correspond to the actual method, and define respectively an operational and strategic module, and a financial module. The first module contains all the physical criteria and parameters that can determine if the objectives of performance are realised or not ex ante. The second module translates into financlal informations this physical criteria and parameters of the operational and strategic module. The interest of this distinction is to show the importance of tangible and intangible benefits in the decision process, even if they don't appear clearly in the financial module

Texto completo da fonteThe purpose of this thesis is to analyse the relations between the middle eastern oil producing countries. How economics can contribute to better explain the production behaviours of theses countries ? What about the effects ? This study is based on : - an empirical analysis of the real production strategies of the middle eastern countries, which mostly belong to the OPEC. We will try to concentrate on the following notions : cooperation/conflict/rationality of behaviours. Also, we will demonstrate how the study of international relations, especially the exercise of influence between nations, can contribute an original point of view ; - a theoretical analysis : what kind of solutions the economic theory can provide, as it may be classical or modem (particularly the game theory), to explain these behaviours

Texto completo da fonteThe market constraints which are put on manufacturing enterprises make those enterprises seek new organizations, for production systems as well as for their command and control methods. We propose a model in which we can accurately represent the physical and the command parts of such new organizations, aimed at dynamical command and control. We propose, at various levels in this model, the introduction of a distributed decision policy, based on computer sciences techniques, such as connectionism. This policy is aimed at smoothing the parts flow through : - a dynamic priority management system - cooperation for the shop-level decision system - auto-adaptation for certain heuristics in the workshop control system. The goals are mainly the increase of the production system reactivity towards unplanned events and production management system constraints

Texto completo da fonteIn this thesis, condition-based maintenance strategies are proposed for production systems of goods and services. These strategies are developed while taking into account the environmental degradation caused by the deterioration of the production system. The system is subjected to random deterioration which impacts the environmental quality. The proposed maintenance models aim to assess the system deterioration in such a way to reduce the environmental degradation. To control this deterioration, inspections are performed on specific dates. The objective is to determine optimal inspection dates which optimize a given performance criterion. Two mathematical optimization models are then proposed in this thesis. The first model considers the average total cost per time unit, while the second model considers the stationary availability of the system. The constrained optimization has also been discussed in this work where the objective is to minimize the average total cost per time unit under an availability constraint or to maximize the stationary availability of the system under a budget constraint. On the basis of Nelder-Mead method, inspection dates as optimal solutions are computed for each optimization criterion. Numerical examples are provided to show the applicability of the proposed condition-based maintenance strategies

Texto completo da fonteNowadays, the enterprises move under a hard competition. The satisfaction of the client in time becarne a difficult spot. Since that, the majority of the actual Company cal1 upon to the subcontractor in order to cover the client demand and to reduce the demand loss. In fact, it's time to expand new maintenance/production strategies by taking into account the context of subcontractor. In this memory we treat some maintenance policies integrated with production under the subcontractor constraint. The manufacturing system under consideration consists on machine Ml which produces a single product. In order to satisfy a constant demand d, the system called upon to subcontractor. The subcontractor is presented by another machine M2 which produces at a certain rate the sarne type of product as Ml. Both machines are subject to random failures. An age-limit policy is used for preventive maintenance of machine Ml. Point of view maintenance actions, the subcontractor is not controlled by us. We considered that the subcontractor imposes some unavailability periods. That's why we suppose that the failure rate of the subcontractor is constant. In this work we elaborated different strategies integrating maintenance and production. In these strategies we are taking in account the constraint of subcontractor. These strategies are optimised and its performances are compared to a simple maintenance policy SMP in which we don't taking in account the subcontractor. Finally, we classified al1 the strategies developed in this work according its performances orders compared to SMP and noted the performance constraints of theses policies

Texto completo da fonteIn this PhD work we focus on the wind farm (WF) active power control since some of the new set grid requirements of interest can be expressed as specifications on its injection in the electric grid. Besides, one of our main objectives is related to the wind farm power maximization problem under the presence on non-negligible wake effect. The chosen WF control architecture has a two-layer hierarchical distributed structure. First of all, the wind turbine (WT) control is addressed. Here, a nonlinear controller lets a WT work in classic zones of functioning as well as track general deloaded power references. This last feature is a necessary condition to accomplish the WF control specifications. Secondly, the high level WF control problem is formulated as an optimization problem distributed among the WTs. Two novel distributed optimization algorithms are proposed, and their performance tested on different WF examples. Both are based on the well-known particle swarm optimization algorithm, which we modify and extend to be applicable in the multi-agent system framework. Finally, the overall WF control is evaluated by taking into account the WTs controlled dynamics. Simulations show potential significant power gains. Eventually, the introduction of a new control level in the hierarchical structure between the WF optimization and the WTs controllers is proposed. The idea is to let further cooperation among the WT local controllers, via a consensusbased technique, to enhance the overall system performance

Texto completo da fonteInteraction with interactive systems is a complex situation in which one or more users interact with one or more systems. To fully understand an interaction, it is ideal to experience it or, at least, to be able to see it in action, which is not always possible. However, the main medium to communicate research in Human-Computer Interaction (HCI) remains research papers, generally in PDF format, and as a result, more and more figures illustrating new interactions are being produced. The objective of this thesis is to study the strategies and tools used to create such figures. First of all, we enrich the current theoretical knowledge on the creation of figures illustrating the interaction by proposing a new taxonomy of the conceptual and visual attributes that compose 795 figures extracted from research articles in HCI. We also present a set of illustration strategies identified through the analysis of the relationships between these attributes. Then, we look at the practical aspect of the creation of these figures and support the hypothesis that 3D scenes staging is an interesting alternative to create figures representing interaction. We then present Esquisse, a tool offering specific rendering effects and interaction techniques that allow both novice and expert users to efficiently produce figures illustrating the interaction. Finally, this thesis presents a study on 3D object rotations, a task that has been described as complex when staging 3D scenes. We study the techniques of virtual control spheres and show that some factors, such as the size of the sphere, have an influence on the behavior of users during rotation tasks. The work presented in this thesis thus provides a first theoretical and practical framework to inform future research and tools for the production of figures illustrating interactive scenarios

Texto completo da fonteIn 2007 with the renewable energy directive, the European Union established the development of a low-carbon economy. This directive aims to decrease greenhouse gas emissions by increasing the energy produced by renewable energy. Already today, the massive diffusion of renewable systems is tangible in the European electricity mix. However, in spite of their potential benefits, their large-scale integration leads to new technical and regulatory questions. Consequently, new management strategies need to be developed and applied in order to ensure a reliable and economical operation of the system. Microgrids are considered to be one of the most effective and flexible solutions able to meet these new needs.The main goals of this thesis are the conceptualization, development and implementation of different management strategies for microgrids. The algorithms developed aim to facilitate the massive integration of renewables and at the same time lead to an effective and economic operation of the systems. A new architecture of distribution grids based on cluster of microgrids was proposed. Each microgrid is composed of a number of renewable-based and conventional generation systems, storage systems and consumption. An optimal and distributed energy management strategy was then defined and developed. This strategy allows to manage the short-term energy management and real-time control of microgrids by using the connected sources in a smart and cost-efficient way. A multi-agent system and the mixed integer linear optimization technique were used for the implementation of this strategy.From a global point of view, each microgrid is seen as a coherent entity, which can support network operation by using its flexible and aggregated sources. Hence, the second part of this thesis aims to understand how distribution grids can exploit these cluster of microgrids and their properties. Different mechanisms for the active management of distribution grids are conceptualized from the technical and economical point of view. A new strategy based on hierarchical management of different smart levels allow to reduce the complexity of the system and to implement a more flexible and extensible system, thanks to a more local use of model knowledge and users behaviour. On the end, the theoretical work were tested on an experimental test-bed in order to show the effectiveness of the proposed theories

Texto completo da fonteAgricultural expansion and intensification have disastrous consequences on biodiversity. Studying the relationship between biodiversity and food production can help devise appropriate measures.The objective of this work was to reveal land use strategies to halt the decline of farmland birds while maintaining agricultural production.Our work was based on the study of correlations between agricultural land use, food production, and various bird community descriptors across French agroecosystems.In high crop production regions, we observed low-diversity communities dominated by few arable specialist species. In high livestock production regions, we observed communities dominated by generalist bird species. The land-use strategy that maximized the Farmland Bird Index under crop and livestock production constraints involved a decrease of crop intensity in the most intensive crop regions and an increase of livestock intensity in the most intensive livestock regions. Extensive livestock production was reinforced in current extensive areas.Our results have shown that different strategies are needed in crop-dominated and in livestock dominated regions

Texto completo da fonteIn Mexico, agricultural markets have been deeply reformed since the 1980s. The purpose of this thesis is to assess the impacts of the agricultural reforms on the livelihood strategies of Mexican dairy farmers. Agricultural policies and their impacts on the dairy chain have been analysed, and a survey of 236 dairy farmers was conduced in order to determine their resource portfolio and their livelihood strategy. Faced with the opening of the national market, dairy households have adopted different diversification strategies, according to their resource endowment and their income: better off households have adopted more qualified strategies, such as migration or non agricultural employment, which reduce their risk exposure and allow them to invest profit in their farm, while the poorest households have adopted less qualified strategies, such as precarious and informal employments in construction or agriculture, which increase their vulnerability and offer few upgrading opportunities

Texto completo da fonteThe results of an archaeological research in the south-western portion of Tandilia System and Interserrana area (Humid Pampas subregion, Buenos Aires Province, Argentina) are presented. The main objective of this thesis is the study of provisioning and exploitation of lithic raw materials by prehispanic pampean hunter-gatherers during the late Holocene. To understand how rocks have circulated and which mechanisms were used for their supply, lithic raw materials available in the studied area and the activities carried out by prehistoric groups in the outcrops are characterized. The methodologies for lithic artefacts analyses that have been used in the pampean region are also discussed. From this background, and also applying structural analysis methodologies derived from the French School, archaeological assemblages of lithic artefacts were analyzed. During the field surveys in the studied area, a variety of rock outcrops were located, and evidence of phtanite and silicified dolomite exploitation was also recognized. The study of lithic materials recovered from two archaeological sites associated to the exploitation of silicified dolomite (Cerro Tres Lomas 1 site) and phtatinte (Cerro Núcleo Central 1 site), made possible to know how the debitage of these rocks was carried in the past. To sum up, this research allowed new lithic raw material quarries to be recognized for the pampean region. From the technological analyses of the lithic artefacts recovered at the quarry-workshops, it is propose that silicified dolomite left these sites as cores, flakes and blanks. In the case of phtanite it is inferred a transport from these sites as natural bloc, cores and blanks. All the information gathered in this thesis is a contribution to understand how the prehistoric pampean groups exploited silicified dolomite and phtanite form the beginning of their debitage

Texto completo da fonteIn this thesis, we designed a simulation platform to compare and evaluate production planning and order management strategies for lumber production in North American sawmills. In our context, a strategy is composed of several parameters such as the choice of order acceptance policies, allowing to accept or refuse an order based on implemented rules, the choice of planning models and algorithms used at each stage of timber production, the choice of model at the tactical level, the coordination mechanisms used, to better coordinate the operations of several distinct entities or of several planning levels; this includes the exchange of information between tactical and operational planning levels or between entities / models used at the operational level to plan timber production. Today, it is extremely difficult for a company to know which management strategy to put in place. The general objective is then to evaluate and compare tactical and operational planning strategies for timber production, taking into account the company's market context and its production parameters. To achieve this goal, we divided it into four specific objectives that resulted in three publications. In the first specific objective, we developed a simulation model to represent the generation, acceptance and sale of an order for a sawmill. We coupled a production planning module to this simulation model that is responsible for inventory management and the generation of production plans. In a second objective, we use this simulation model to be able to evaluate the impact of order acceptance policies such as Available-to-promise (ATP), Capable-to-promise (CTP) and Stock policies on the company’s performance in terms of volume of accepted orders in a product flow environment diverge with co-production. Although these order acceptance policies have been widely studied in a traditional manufacturing context, the choice of one policy over another is far from being trivial in such a context of divergence flow. We show that in this type of context, the choice of an order acceptance policy rather than another depends strongly on the market and impacts the performance of the company, in terms of accepted orders and average annual inventory. This specific objective leads to the first publication. In a third specific objective, we evaluated coordination mechanisms used at the operational level between the different activities of the timber processing process, which is a decentralized process. The previous simulation platform has been adapted and previously published coordination mechanisms such as "Two-phase planning" or "bottleneck-first planning" are evaluated using a rolling horizon in an environment where orders are generated dynamically. We show that coordination mechanisms already published and tested in a static environment perform poorly in a dynamic environment. We therefore propose another "hybrid push / pull" coordination mechanism exploiting the decoupling point concept. This mechanism is better than the previous ones by allowing a greater number of sales, as well as a reduction in average inventory. This specific objective leads to a second publication. Finally, in a fourth specific objective, we are interested in production planning at the tactical and operational levels. We use the simulation model to compare and evaluate different information transmitted from the tactical level to the operational level by simulating the production system, the planning process and the market behavior. The tactical planning level is then taken into account to establish longer-term production planning. We show that the choice of the type of information to be transmitted from the tactical level to the operational level varies according to several factors, such as: the order acceptance policy (ATP, CTP) used by the company, the extent of seasonality selling prices, or whether or not being in an overcapacity market. This specific objective leads to third publication

Texto completo da fonteL’industrie forestière est un secteur économique générant beaucoup d’emplois au Québec, Canada. Dans le but d’assurer la compétitivité et la profitabilité des scieries, plusieurs propriétaires se voient donc dans l’obligation de revoir leurs systèmes de production. De plus, ceux-ci sont à la recherche de nouvelles opportunités pour générer des profits, comme le programme de gestion de la demande en puissance (GDP) d’Hydro-Québec, programme visant à redistribuer l’usage de l’électricité vers des périodes hors-pointe. C’est dans cette optique que s’insère cette maîtrise, dont le but est d’évaluer l’impact technico-économique de l’implantation de stratégies permettant à une scierie typique de participer au programme de GDP. Pour ce faire, une revue de la littérature a été faite, afin d’établir un état de l’art sur les systèmes de gestion de l’énergie en industrie, la gestion de la demande en puissance et les modèles de planification existants dans le milieu de la fabrication de bois d’oeuvre. Ensuite, l’étude d’un système de production de bois d’oeuvre réel et la collecte d’informations quant à la consommation d’électricité des équipements et de chauffage des espaces de travail utilisés ont été réalisées. Ces informations ont par la suite été intégrées à l’intérieur d’un modèle de planification tactique des opérations. Avec un tel modèle, il devenait donc possible de tester différentes stratégies permettant de réduire l’appel en puissance des équipements en cas d’évènement de GDP et de mesurer les gains financiers ou encore les pertes engendrées par la mise en place de telles stratégies. Plus particulièrement, six stratégies ont été testées. À la suite d’une étude comparative basée sur la profitabilité de chaque stratégie, il s’est avéré que le meilleur scénario permettait d’augmenter les profits de la scierie à l’étude de près de 5%, tout en offrant une augmentation de profit durant un grand nombre d’heures de GDP (68 heures). Somme toute, l’étude a permis de trouver, pour une scierie type du Québec, la meilleure stratégie à mettre en place pour participer au programme de GDP d’Hydro-Québec. Elle a également a permis de développer un modèle de planification pour l’industrie du bois d’oeuvre intégrant la facette énergétique et de générer une méthodologie générale permettant de reproduire les travaux réalisés dans le cadre de la recherche à d’autres secteurs.
The forestry industry is an economic sector that generates a lot of jobs in Quebec, Canada. In order to ensure the competitiveness and profitability of sawmills, many owners are therefore obliged to review their production systems. In addition, they are looking into new opportunities to generate profits like Hydro-Quebec's Demandresponse program (DR). It is in this perspective that this master project is integrated, whose aim is to find the best strategy at the level of profitability, for a typical Quebec sawmill, to participate in Hydro-Quebec’s DR program. To this end, a literature review was conducted to establish a state of the art on energy management systems in industry, on demand-response programs and on existing planning models in the lumber manufacturing industry. Then, the study of a real lumber production system and the information collection about the equipment electricity consumption and the workspace heating used were realized. This information was subsequently integrated into a tactical operations planning model. With such a model, it became possible to test different strategies to reduce the equipment power demand in case of DR event and measure the financial gains or the losses generated by the implementation of such strategies. More specifically, six strategies were tested. As a result of a comparative study based on the profitability of each strategy, it turned out that the best scenario allowed the sawmill profits to increase by almost 5% while offering a profit increase for a large number of DR hour (68 hours). All in all, the study found that, for a typical Quebec sawmill, the best strategy to put in place to participate in Hydro-Québec's DR program. It also helped develop a planning model for the lumber industry integrating the electrical energy facet and generates a general methodology for replicating the work done in the present research to other sectors.

Texto completo da fonterecherche est également la construction d'une démarche permettant d'identifier et de caractériser les facteurs clés d'efficacité à partir desquels se joue la compétition dans les deux pays.
Le travail place au centre de la réflexion les stratégies d'entreprises, et plus particulièrement les stratégies concurrentielles, définies par PORTER.
Notre thèse centrale est que l'efficacité de l'entreprise de construction est fortement associée aux gains d'efficience obtenus selon une logique technico-économique. Des gains sont acquis en agissant sur des procès, entendus comme des
regroupements cohérents dans le temps des activités qui mènent à l'obtention d'une véritable valeur ajoutée au produit-bâtiment. Ces actions se matérialisent à travers des outils et des méthodes d'organisation et de gestion. Elles portent non seulement sur des aspects locaux, mais aussi transversaux, exigeant d'intervenir aussi bien au
sein de l'entreprise de construction elle-même, qu'au niveau des acteurs du secteur et de leurs relations.
Les nouveaux enjeux concurrentiels et de marché dans le Bâtiment / Logement constituent donc l'occasion de revenir sur la problématique de l'entreprise de construction face à l'efficacité. Les pays comme le Brésil, où l'efficacité commerciale
et l'efficience financière primaient traditionnellement sur l'efficience technique, n'échappent pas à cette règle.

Texto completo da fonteIn order to improve the « effectiveness » of building construction firms, we have studied the « new types of rationalisation of production » in France and in Brazil. For us, effectiveness is the capacity of the firm to hold constant or even to increase its level of activities. Efficiency is the firm’s capacity of performance through the entire « production process ». One of the results of this research is the construction of a special procedure that allows us to identify and to characterise the « main factors of effectiveness » that are at play in competition between firms in both countries. Thereby, the procedure allows us to identify and to analyse the « new types of rationalisation of production » that firms put into practice in order to be efficient in this competition. The investigation described in this thesis centers around the strategies of the firms, especially the « generic competitive strategies » developed by PORTER. To survive, the firm must win the competition by producing « better » or by producing « cheaper ». Our main thesis is that building construction firm’s « effectiveness », nowadays, is closely associated with the gains in « efficienty » achieved by the application of technical and economic approaches. Savings are obtained by improving the phases of the « production process » in general of the phases of « production system » in particular. These improvements are articulated by mans of the « processes », sets of activities that are put together in a coherent way, that lead to a real gain in the value of the building-product. These « processes » are put into practice through tools and methods used by the organization and the management. They concern both local and transversal aspects, that act both on the struture of the building construction firm and on the other actors of the building industry. All actors must question their roles, their strategies, the form of their organization and managemet, and either their relationship of their collaborations with the other actors. The survival and the prosperity of each actor and the industry depends on of all these issues. This new competitive stakes of the building market represent the occasion of rethinking the construction firm’s policies in regards to « effectiveness ». In this respect, even countries like Brazil, where commercial « efficiency » and financial « effectiveness » has always commanded over technical « effectiveness », are concerned

Texto completo da fonteCe mémoire s’intéresse à la rencontre de l’objet-chanson et du théâtre dans le cadre d’un concert de chansons. Il le fait à travers trois corps: le chant-acteur, le musicien-acteur et le «corps» musical. La visée principale de cette recherche est de dévoiler et de tester des stratégies de théâtralisation brouillant la frontière entre les genres, avec le désir de donner au concert de chansons toute l’amplitude qu’il peut prendre, voire de lui ouvrir les portes d’un nouveau langage. Pour ce faire, après avoir analysé un corpus d’œuvres au profil hybridant, nous avons cherché des pistes de réponse à nos questions de recherche dans des ouvrages dédiés à la musique contemporaine. Les hypothèses issues de cette phase de travail ont été mises à l’épreuve lors de la création du spectacle expérimental Le spectacle raté de la chanteuse écrapoutie. Le présent essai retrace donc ce processus en mettant en évidence les stratégies qui nous ont semblé les plus efficaces, tant parmi celles que nous avions formulées au départ que parmi celles qui sont nées du travail de création lui-même. En annexe, le lecteur pourra consulter nos différents outils de travail, suivre notre processus de création en images et lire la partition finale du spectacle en version simple ou commentée. Un enregistrement du spectacle est aussi disponible.

Texto completo da fonteThis research falls within the scope of strategic management, corporate communication, and language science. It includes the strategic and managerial dimension of the discourse of french managers in charge of large companies. The approach favoured, both empirical and inductive consists in the techniques of content analysis and lexicometric analysis. The study is based on a sample of 500 "messages" taken from managing directors' annual corporate reports during 4 periods of observation : 1976, 1983, 1987, 1991. The thesis is divided into 4 parts. The first part sets out to highlight concepts so as to identify the foundary qualities of strategic thinking, the dissemination of, and the scope of strategic corporate discourse, then its informative and persuasive functions (of rationalization, energizing, confidence, identity, legitimacy. . . ). The second part bears out the methodology using a variety of studies and methods. The third part is devited to the conditions in which the "messages" were produced and their explicit and implicit content (performative, normative and magic discourse). The long term development of managerial language is analysed through 12 dimensions structuring the thesaurus built up (strategy, context, actors,. . . ), the diversity of representations conveyed and the rethoric implemented. The last part focuses on the contingency of discourse in its strategic vocation. The lexical content and the lexical content and the thematic structure of the "messages" highlight the mains concerns, the coherence of their construction and thier pathology. The use of techniques of data analysis reveals the discrepancy between different speech logics (E. G. : factual vs managerial). Finally, it is the combinations of these which make up, firstly, a typology of forms of managerial language (or strategies of discourse) and secondly, a typology of managing directors. These results are assessed via profile characteristics of companies

Texto completo da fonteWith the development of fuel cell (FC) and water electrolysis technologies, electrolytic hydrogen is becoming a pillar of the energy transition, a substitute for fossil resources and a tool for integrating intermittent renewable energy sources (RES). On the scale of isolated or islandable microgrids, this transition is based on the development of hybrid systems, coupling photovoltaic (PV) panels and electrolyzers for hydrogen production, storage systems - hydrogen (H2) tanks and batteries (Bat) - and FC for electricity production. This study presents control strategies for a PV-H2-Bat-FC system to optimize intermittent PV energy management while respecting the operating conditions of electrolyzers and FC. First, a MPPT (Maximum Power Point Tracking) control system is developed to ensure the operation of PV at maximum power, and a control strategy based on Model Predictive Control is implemented to define a current reference for the FC, the electrolyzer and the batteries. Secondly, IP controllers are used to regulate these currents. Thirdly, an optimization problem makes it possible to define a commitment plan to use the FC and the electrolyser taking into account energy supply, demand and stocks

Texto completo da fonteThe general study framework is built around the maintenance management integrated with the production, taking into account the constraint of subcontracting. Our research specifically addresses the economic management of the production delivery from one or more subcontractors that differ in their availability and cost per unit of production. The economic study consists in minimizing the total cost including production, inventory and maintenance. Our study will be conducted along two axes. In a first axis, we consider a constant demand on an infinite time horizon. An analytical study is conducted to determine the maintenance policy to be adopted and the choice between several subcontractors. In a second axis, we considered a random request to accommodate over a finite time. This application must be met in a required level of service by using outsourcing while assuming that the failure rate of the main machine varies with use and time. The objective was to propose an optimal production maintenance plan that satisfies the level of service and taking into account the deterioration of the machine while minimizing production, inventory and maintenance costs. The analytical models developed in the two axes are validated by numerical examples and interpreted through sensitivity studies

Texto completo da fonteDe nouveaux systèmes de production flexible se développent depuis les années 1990. Ils sont basés sur des réseaux d'entreprises, très mobiles et très réactifs, et montrent des spécialisations spécifiques de leurs marchés. Ils sont surtout le fait de communautés de Chinois d'Outremer, d'Indiens, de Libanais et d'Italiens. Ces quatre types de réseau sont en fait très semblables dans leur organisation. Les entreprises concernées sont simultanément en coopération et en compétition, d'où le concept de coo-pétition. Leur compétitivité se base sur l'échange d'information et la minimisation des coûts de transaction.
A la croisée de l'économie, de la géographie, des sciences régionales et de gestion, un modèle théorique généralisé de la production en réseau explique tous ces différents réseaux d'entreprises. La confiance et la réputation sont institutionnalisées. L'intermédiation entre les acteurs a ont un rôle essentiel. Le concept de dimension de la transaction est proposé. Dans cette dimension, les entreprises optimisent leur localisation grâce la hiérarchisation des relations entre acteurs et leur communautarisme. Le modèle explique aussi la dynamique des réseaux, la résilience de leurs propriétés, l'emboîtement de leurs échelles de structuration.
Des systèmes multi-agents basés sur Visual-Basic et sur Cormas permettent de valider expérimentalement le modèle, en simulant les réseaux d'entreprises et leurs dynamiques.

Texto completo da fonteBased on the cognitive model of human production of Anderson, we considered in this thesis, a large part of the learning strategies presented in the various classifications as universal human process system production. In this context we examined the strategic difference of learners, as some argue, and the modification that could produce training in the use of learning strategies in the repertoire of strategies learners.We have shown that the development of language skills is based on the activation of general procedures for solving problems governed by universal strategies.We are particularly interested in this thesis, in the universal nature of learning strategies. In this perspective we conducted an empirical study which aims at analyzing learning strategies of two groups of Iranian adult learners, one of which received training in the use of learning strategies learning. The results of our analysis of their oral and written productions have confirmed the theoretical basis of our research. Indeed, the teaching of learning strategies, that offer some, do not change the use of learning strategies and their language productions depend on their declarative knowledge. .Keywords: cognitive model of human production, learning strategies, training in the use of learning strategies, declarative knowledge, Iranian adult learners

Texto completo da fonteThis thesis examines the interactions of transactions entailed in the process of setting up residential and industrial Mega-Projects. In Chennai (capital of Tamil Nadu, India), the regional government has been promoting Economic Development Corridors, which, for over two decades, have been transforming hectares of private agricultural lands, public lands and even entire villages. Although research on public policies, foreign private investment or land conflicts is well documented, little attention has been paid to the upstream mechanisms, the multiplicity of negotiations and the historical context in which those projects develop. By studying the interaction between villages and projects and the social and spatial local transformation taking place, this work presents a new perspective : how do local actors appropriate those vectors of growth to strengthen and defend their social position? Using ethnographic methodology, we describe and examine the meaning of land and land acquisition practices in order to bring to light the "micro-logics": fragile and uncertain processes in which actors implement non-linear and flexible strategies. This approach allows highlighting the paradoxes inherent in the process of project concretisation and which result from power relationships and compromises. In addition, it allows to unpack "land innovations processes" which emerge from legal norms, the interplay of political forces, beliefs and social roles
