Calasans, Jorge Thierry. "Le concept de ressource naturelle partagée : application au ressources de l'eau : l'exemple de l'Amérique du Sud." Paris 1, 1996. http://www.theses.fr/1996PA010292.
Full textThis study, in the field of both public international law and environmental law, deals with the concept of "shared natural resources" and its application in the joint management of water resources, especially among south American countries. "shared natural resources" is a concept established in the seventies, and was used in various bilateral and multilateral treaties, particularly those concerning the production of hydroelectric power. Some treaties are analyzed, as well as the united nations environmental program draft principles concerning the harmonious utilization of shared natural resources, and the international law commission draft project on the law concerning the utilization of international rivers. The study is divided in two parts. The first one deals with water as a "shared resource", that is, the evolution of the juridical approach of international rives and the problems arising from a fragmented perception of water resources. The second part studies, in a more pragmatic way, the application of the concept in the joint management of the plata and amazon basins. It also presents the use of the concept in other parts of the world (especially in the Rio Grande and Mekong basins) and in the field of resources other than water (straddling resources and resources above national jurisdictions)

Full textThis study questions the orchestration, by firms, of customers as resources, and to what extent it unveils new growth drivers in unstable competitive environments. Customers possess a diversity of resources and competences that can be collected, combined and leveraged by companies to create economic value. To seize this opportunity, organizations design new business models based on the exploitation of those resources. To shed light on this phenomenon, we rely on the concept of resource orchestration. We investigate what resources and competences firms collect to structure their resource portfolio; how they combine them to build new capacities; and how they deploy these capacities to create more value for customers. This work is based on the study of seven cases of customers as resources orchestration. We conducted interviews and collected netnographic and secondary data. Based on our analysis we explain how organizations combine customers’ inputs, creating new capabilities to improve the creation of value for consumers and the capture of economic value for the firm. This work invites us to apprehend organizations orchestrating customers as resources as open systems in constant interaction with their strategic environment

Lucas, Rémi. "Planification adaptative des ressources ferroviaires." Electronic Thesis or Diss., Institut polytechnique de Paris, 2020. https://theses.hal.science/tel-03009036.
Full textRailway planning consists of drawing up a transportation plan before operational time, specifying a planning for each resource: the train paths, which correspond to the schedules, the rolling stock that will be used to move the trains, and the crew on board the trains. Given the complexity of the railway system, this transportation plan is carried out potentially several years in advance, when a precise transportation plan is drawn up.However, once a resource has been planned, it is sometimes necessary to adapt the transportation plan and therefore change it. There may be many reasons for this: schedule changes due to work, partially damaged infrastructure, request for an additional train set for a train, damage to a type of rolling stock, etc. Thus, the transportation plan may sometimes be adapted several times between its design, potentially several years in advance, and its execution on the day of traffic. It is therefore legitimate to ask whether the design of a precise transport plan with such large time scales is reasonable.In this thesis, we consider the adding of flexibility to the planning process so that the effort to adapt the transportation plan when necessary is reduced. We introduce the notion of transportation plan adaptation costs, and we propose to make these adaptation costs explicit for the rolling stock resource. In particular, we specify the structural adaptation costs, which make it possible to quantify the similarities between two different rolling stock plannings. Adaptive planning consists in anticipating possible future adaptations of the transport plan as early as the design phase. Several Integer Linear Programs are introduced and experimental results are proposed on real SNCF instances. The adaptive planning approach can be compared with the current approach, and it is shown that the adaptation costs can be effectively reduced by adopting this new way of planning

Full textThe thesis focuses on the evaluation of the Mauritanian demersal fishery resources and the health of the ecosystem as a whole. The biophysical environment and fisheries of the Exclusive Economic Zone are presented in the first chapter. The too following chapters deal with the implementation of a series of stock assessment methods. These methods are first implemented to assess the stock status of white grouper, and then applied more broadly to 22 demersal species. Combined assessment of all stocks indicate an overall overexploitation of demersal stocks, with a current fishing effort that exceeds EMSY by around 30%, and a biomass that has been divided by about 3 since 1982. This third chapter is also an opportunity to discuss more theoretical aspects based on a comparative ecological approach to analyze factors that explain stocks resiliency. These analyzes show that stocks whose index of vulnerability is high and stocks of larger species are those that support the highest fishing pressure, but also those who are currently the most exploited. The last chapter aims at replacing the demersal resources dynamics into ecosystem global dynamics. It is based on the update of an existing Ecopath model, and the development an EcoTroph model. This approach enables a diagnosis at the ecosystem scale. It also highlights the strong interactions between fisheries, particularly between the small-scale coastal fishery (PAC) and the pelagic fishing industry, but also between CAP and the demersal fishing industry. This analysis is very useful for the construction of fisheries evolution scenarios, and ecosystems diagnosis in the region

Full textÀ partir d’une classification des conflits selon une typologie des Etats du monde d’inspiration Centre-périphérie, l’argument principal de ce travail consiste à expliquer les conflits liés aux ressources naturelles – et plus largement tous les conflits – par l’amplification de deux phénomènes :le déclin de l’activité économique et l’exacerbation des tensions politiques. L’examen d’une série de cas (Aceh, Colombie, Angola, Afghanistan, Sierra Leone, Liberia, Cambodge) confirme la lecture matérialiste politico-économique des conflits liés à l’exploitation des ressources naturelles. Le rôle des structures d’appropriation du pouvoir et des revenus, en particulier de la rente des revenus issus de l’exploitation des ressources naturelles – cruciale dans des économies peu industrialisées – apparaît à la lumière du jour.
Enfin, ce travail offre quelques réflexions sur l’influence des structures d’appropriation dans l’éclatement et la durée des conflits. La question de l’origine des structures d’appropriation et de ses liens présumés avec la diffusion de la propriété privée en parallèle avec le développement du système-monde est ainsi développée, précédant la critique du rôle pseudo-développementaliste des ressources naturelles, dont le résultat de l’exploitation est surdéterminé par les structures d’appropriation locales (Tchad). Le travail se conclut sur une mise en perspective des enjeux du contrôle des territoires où sont exploités des ressources naturelles et de l’apport de cette question dans l’élaboration d’une géographie de la violence.

Full textThis thesis constitutes a study on renewable resource economics. Chapter 2 presents two types of extracting behaviour in two optimal control models, continuous and impulse control. Chapter 3 analyses stock dependent instruments and shows their advantages. Chapter 4 compares the two types of extracting behaviour and demonstrates that the impulse control generates higher gains, whereas fiscal revenues and stocks are not always higher. Chapter 5 establishes a dynamic game and shows that the scope for cooperation between heterogeneous agents is greatest for intermediary levels of heterogeneity. Chapter 6 studies forest exploitation and fiscal- and regulatory systems of the forest sector in the Democratic Republic of Congo and in France. Finally, chapter 7 presents a study on forest biodiversity and indicates the economic criteria and cutting strategies that are beneficial for biodiversity preservation

Full textThe growing congestion of road infrastructure, particularly in urban areas, is alarming and requires solutions to increase the logistics productivity. To achieve this goal, we propose an innovative strategy among all actors of the logistic chain which relies on the mutualization of unused logistic capacities. The purpose of this sharing policy is to create a new network of logistic services able to increase the overall ability of the system to satisfy efficiently new demands. Starting from a set of data describing the logistic system and from the set of demands, we determine the transportation route of the demands in order to maximise the revenue generated by demand acceptation. Our problem consists of the allocation of demands on the network of logistic services. A first contribution of this dissertation is our model of the logistic services based on a time-space network, which allows us to express the set of movement possibilities for each service, whatever the transportation mode might be. As opposed to long haul transportation problems, urban transportation services are not necessarily restraint to direct transportation. Next, we handle the demand allocation problem as a multi-commodity flow problem and propose a mathematical formulation. A second contribution consists of proposing a series of techniques for reducing the size of the formulation such that bigger instances can be solved in a reasonable time. For industrial use, we complete the mathematical formulation in order to consider variants of the demand allocation problem. In the last part of this dissertation we describe the integration of the demand allocation module in a software solution for industrial use

Full textThis thesis investigates the determinants of cultural heritage tourism development. Part one is devoted to the notion of heritage, as well as economic issues related to its valorisation. Part two provides a theoretical and conceptual framework that takes into account the specific nature of heritage, and addresses heritage market mechanisms through the notions of absolute and differentiative advantage. Special attention is also being paid to heritage activation process. In part three, this research questions the relationship between cultural resources of outstanding universal value, valorisation through a proven labelling strategy (or at least portrayed as such), and major tourist attraction status, through the analytical lens of UNESCO world heritage list. Econometric modelling is then employed to study the relative contribution of keys cultural heritage features upon tourism and socio-economic performance at the Midi-Pyrénées’ cantonal scale. Our results show that heritage’s potential impact on tourism development is strongly related to its own intrinsic cultural value. However, the real impact of heritage depends more on the way resources are being used, and on the economic environment in which these resources are being brought into the market. Even though labels hold a central position in tourism development policy, the tests we conducted do not provide any conclusive evidence of a quantifiable economic impact. Labelling strategies may act as a catalyst for tourism and economic development, yet expected benefits remain highly contingent upon the sites’ pre-labelling economic profile, as well as the nature of the interventions that accompanies designation

Full textWe first study the problem of growth non-renewable resources within a Schumpeterian endogenous growth model. We examine the optimum and equilibrium paths at the steady-state, and we also study the impact of an economic policy aimed at implementing the optimum. In particular, it turns out that a research subsidy has the same impact as a technical progress in exogenous growth models. We then analyze the impact of the pollution generated by the use of non-renewable resources on the standard results of the literature. In this context, we define a new condition depicting the extraction path, the modified Hotelling rule, and we show that an increase in the houselolds' psychological discount rate leads to a situation in which the social planner slows down the extraction. Finally, we present a simple endogenous growth model that allows us to analyse the effects of an environmental policy. In particular, we show that a decreasing tax on the resource use yields the optimum

Full textTo exceed the debate concerning the superiority of the scientific organization of the work on the organic structure, theories have linked the organizational choice efficiency to characteristics of the environment (theories of the contingency), to the nature of the competitive advantage (the strategic analysis) and others establish a link between the environment, factors of competitiveness and the organization of the work (the economy of institutions). The analysis of the banking sector shows that with the evolution of the competitive environment, banks has passed from a strategy of financial intermediation to a strategy of financial service distribution and pme financing. This strategic evolution has necessitated the decentralization of decision making into branches. This evolution has generated a double disequilibrium of competence : an excess of administrative people and a lack of commercial staff. Changing from an internal market tradition in the seventies, banks in the eighties tended to resort to external flexibility and then to reconstitute their internal market in the nineties. Banking products and computer technologies being available on the market, couple with a qualified labor force lead us to believe that external flexibility should be more efficient. The return to internal flexibility constitutes a paradox with the respect to the institutional economics theory which explains the arbitration between the coordination bargains and the administrative coordination by the degree of asset specificity. The internal market reconstitution is explained by the coproductive nature of services in which the consumer intervenes. The creation of a link of confidence in the banking relationship and the social capital accumulation by banking counselors are fundamental in the evaluation of risks and the financial services distribution. This social capital accumulation supposes a durability of the relationship, rendering necessary the stability of banking counselors. The idiosyncrasic nature of confidence relationship generates specific human capital determined by the apprenticeship of a particular social environment, thus justifying the internal market reconstitution

Full textAt the scale of a city, a sustainable water management raises questions about the links between uses and resources: what water quality is needed for what purpose? The Parisian context is a favourable ground for conducting such type of reflection thanks to the existence of a non-potable water network (RENP) dating from the late nineteenth century. The network is currently supplied by summarily filtrated water from the Seine river (20%) and the canal de l’Ourcql (80%). It is mainly used for municipal purposes: Parisian streets and sewers cleaning, water supply of artificial lakes and green areas watering. An alternative model of water management at Parisian scale is today possible thanks to the decision of the City of Paris in March 2012 to maintain and rehabilitate its RENP. This decision has been confirmed by the approval by the Council of Paris in September 2015 of the master plan of the RENP and its uses (“Schéma directeur des usages et du réseau d’eau non potable de Paris”) for the period of 2015-2020. The public company Eau de Paris, responsible for the water service in Paris, is mandated to implement the decisions and orientations of the master plan. In the context of pressure reduction on natural resources, one potential evolution of the RENP management is its resources diversification. The considered potential resources are mine water, treated wastewater, rain water and swimming pool water. The research raises the following question: How and under what conditions can the RENP supply be sustainably managed on the Parisian territory? In order to answer this question, one first carries out a description of the current situation, then one identifies the potential resources and the associated risen questions. Two approaches are proposed afterwards. The first approach involves the definition of several choices of RENP resource repartition, called scenarii. These scenarii are assessed and compared through performance indicators. The second approach consists of the characterization of the actors’ positions regarding the RENP resource diversification. The characterization of the positions is achieved through conducting semi-structured interviews. Results of both approaches are finally discussed.The results of the research will enable to re-examine the question of the relationship between the water uses and the required water quality. It will highlight the brakes and levers for the valorization of alternative resources to drinking water. It will enrich the reflections on the status of drinking water in the context of sustainable water management

Full textThe railway operations' planning consists in finding the best use of the available infrastructure, rollingstock and crew units to cover a given timetable. A commonly adopted scheme breaks down planningas decision-making levels and resources.However, the occurrence of perturbations may deteriorate the quality of the solutions or even makethem infeasible. Therefore, railway operators aim to find robust schedules that minimize the impact ofperturbations. To this purpose, the decisions made for each resource (infrastructure, rolling stock andcrew) must include the demand cover as well as the robustness objectives.Nevertheless, all tested strategies focus on a single resource at a time, neglecting resource sharing andits impact on the robustness. But the sequential scheme of resource planning can increase thepropagation delays on other trains. Integrating of tactical decisions of the three resourcesinfrastructure, rolling stock and crew can result in a more robust schedule that minimizes thepropagation of delays. The main motivations of the thesis come from this idea.The objective of this work is to develop decision support tools that provide an integrated and robustplanning of railway resources at the tactical level. We propose in this thesis several contributions:1. An optimization model that aims to develop a robust transport plan of the three critical resourcessimultaneously.2. A simulation model (discrete event) to assess the robustness of transport plans. We are trying at thisstage to reproduce the actual behavior of the rail system and the use of three critical resources

Full textIn this thesis, we aim at introducing the management of consumable and renewable resources in temporal, parallel and domain-independent planning. As an application of our work, our purpose is to improve the temporal parallel planner named CPT which is not able to manage resources in its original version. In addition, we want to preserve all the original performances of this planner on temporal planning problems. We focus on the total duration of the plan as the optimization criterion. To express resource constrains, we develop a resource-based formalism in relation of the mutual-exclusion-based one introduced by Smith and Weld and used by the CPT planner to express temporal constraints. We propose two different methods to manage resources in the CPT planner: The first one, based on resource links, requires additional resource constraints which must be respected and can resolve temporal planning problems under resources within remarkable search delays. The second one is based on synchronization actions; it is less restrictive than the first method but it requires many additional propagation rules to speed up the search process. In many cases, the synchronization actions-based method finds temporal optimal parallel plans with better quality than the ones found by the resource links-based method

Full textWe have looked for an answer to the following two problems : in one way, to reveal the caracteristics of decentralization in organized establishments, and in another way the research of effects of the decentralization on the social and the general functionning of the company in particular. We put forth a formular which comprases two equivalent variables of organization : "a decentralized structure" and "a decentralized power of decision". From the time of which there is a distribution of power of decision in organization, we have identified the caracteristics of the decentralization : dimension, degree, assessment. This model of specification of the form of decentralization applicable in a general way to organizations, has been applied to decision making of human resources management practised in companies : recruitment, human resources planning of, career management, remuneration, quality circles, training, industriel relations. A systematic approach has allowed us to see the effects of decentralization. In one way, it shows the evolutions of individual and group behavior and the modifications of power relationships, and in another way the variations in organizational dimensions of the company (differenciation, standardization, formalization, planification and control). A conclusion on the efficiency in relation to the organizational profile of decentralization of the company has been put forth
Favard, Pascal. "Exploitation optimale d'un ensemble de ressources naturelles." Toulouse, 1996. http://www.theses.fr/1996TOU10004.
Full textIn this dissertation, we propose to study the optimal exploitation of a set of natural resources, considering that this exploitation is generally a problem of simultaneous management of renewable resources (flow) and non renewable ones (stocks). To do so, we consider a general equilibrium framework where the population has to make trade off at each moment between the quantity of resources consumed and the quantity of leisure. The average work time necessary to extract a resource is supposed constant, although specify to each resource. In the first chapter, we study the case where a plentiful flow is available. We show that it is never optimal to consume the stocks sequentially by increasing cost order. For a non-degenerated subset of stock levels, it is optimal to consume more then two resources simultaneously, and the path of consumption-leisure couples is largely indeterminate. In the second chapter, the flow is considered scarce. The results established in the first chapter still hold. Moreover, for a non-degenerated subset of stock levels, it is optimal to consume the flow before beginning to exploit a stock, even a less costly one in terms of access cost. In the third chapter, unlike previously, we consider a growing population size. There instantaneous utility per capita can grow when the population grows for certain stock levels. Moreover, if society can spare some resource by stocking part of flow, the stock can be valuable as a reservoir

Full textThe aim of this Ph. D. Thesis is to analyze the link between economic growth and environment. We have tried to set a framework which can allow to build environmental policies that insure sustainability of economic growth in the long run. In the first part, we propose a study which supposes that the authorities in charge of environmental policies have a complete knowledge of the structure of natural phenomena technologies and current and future preferences. After a brief survey of the literature, we use a simple model to study conditions in which the economy can evolve along a win-win balanced growth path in the first chapter. In the second chapter, we provide an ethical study of the sustainability concept. In the second part of this thesis, we evaluate the relevance of the models studied before knowing that the main difficulty to come to a decision today in terms of environmental policy is due to our complete ignorance of its long-run consequences, we wonder on the effects of the introduction of environmental uncertainties on the decisions of the central planner. The third chapter analyses two types of environmental uncertainties one is about future generations preferences and the other is on the evolution of environmental resource's stock. At last, in the fourth chapter, we use a microeconomic approach to study the consumers behavior with environmental uncertainty

Full textEconomists have viewed the presence of externalities and other market failures as leading to a private equilibrium that would not be Pareto optimal. In the exploitation of common-pool resources, this would lead to the 'tragedy of the commons'. In dealing with the 'tragedy of the commons', the common solutions promote either state or market involvement. However, the State-market solution to social dilemmas fails to recognize that individuals in a group or a community interact in social context. This thesis explores the role of social heterogeneity in collective action among communities. This is evident in the case of the social dilemmas associated with natural resources. We propose models of compliance (threshold model, static game, evolutionary game) that allow for the existence of a social norm. The impact of the social norm on pubic policy towards externalities is examined

Full textThis thesis focuses on the optimization of the activities of an emergency department (ED) to improve the quality of services offered to patients. The proposed approaches are divided into two parts. The first part consists in the optimization of the ED activities. The objective is to develop a decision support system capable of optimizing human or material resources. To achieve this, we have first developed a performance-evaluation tool based on discrete event simulation. Then, we are interested in the planning and dimensioning of resources. We developed different optimization methods based on mathematical programming, simulation-based genetic algorithm approach, what-if scenario strategy and VIKOR multi-criteria analysis method. In the second part, the estimation of the average waiting time for a patient is achieved by taking into account the optimization of resources. To this end, a comparative study is performed to compare analytical forecasting methods to a simulation model-based approach with Petri nets. These methods are used to predict simultaneously the average waiting time per hour and the waiting time for each patient.

Full textUtilization of natural ressources, in capitalism is explained by economical and political facts. In this text, the notion of space is used for a description of utilization of natural ressources. Management of the firms is examined, on that point of view. In conclusion, it appears that political ecology is opposed to a management which is efficient

Full textSince the 90s, Internet is at the heart of the labor market. First mobilized on specific expertise, its use spreads as increase the number of Internet users in the population. Seeking employment through "electronic employment bursary" has become a banality and e-recruitment something current. This information explosion poses various problems in their treatment with the large amount of information difficult to manage quickly and effectively for companies. We present in this PhD thesis, the work we have developed under the E-Gen project, which aims to create tools to automate the flow of information during a recruitment process.We interested first to the problems posed by the routing of emails. The ability of a companie to manage efficiently and at lower cost this information flows becomes today a major issue for customer satisfaction. We propose the application of learning methods to perform automatic classification of emails to their routing, combining technical and probabilistic vector machines support. After, we present work that was conducted as part of the analysis and integration of a job ads via Internet. We present a solution capable of integrating a job ad from an automatic or assisted in order to broadcast it quickly. Based on a combination of classifiers systems driven by a Markov automate, the system gets very good results. Thereafter, we present several strategies based on vectorial and probabilistic models to solve the problem of profiling candidates according to a specific job offer to assist recruiters. We have evaluated a range of measures of similarity to rank candidatures by using ROC curves. Relevance feedback approach allows to surpass our previous results on this task, difficult, diverse and higly subjective
