This thesis describes the work performed over a six and a half month internship at Eastman Kodak Company in Rochester, NY. The thesis focuses on the implementation of a lean manufacturing system, modeled after the Toyota Production System, in the Kodak color film business. The goal of the system is to systematically eliminate all forms of waste from the production process in an attempt to reduce costs and inventory. This thesis approaches the problem from two different points of view. On the one hand, it takes a high level view of the entire supply chain and describes how material and information should flow through the supply chain. It highlights where inventory buffers should be located and which operations should be improved in order to reduce the size of these buffers. Finally, this thesis highlights the importance of leveling the customer demand signal in order to implement a true pull system using Kanbans. On the other hand, this thesis describes the implementation of lean manufacturing tools such as Kanban systems and Heijunka boards in some Kodak operations. This work includes the use of tools such as visual signals, cellular manufacturing, Kanbans, Heijunka boards, etc. The work performed over the internship sets the foundation for the transformation of the Kodak supply chain into a lean supply chain capable of dealing with uncertain demand. Additionally, the work can easily be transferred and applied to other Kodak businesses such as paper and photochemicals.

Essghaier, Fatma. "Collective decision making under qualitative possibilistic uncertainty : principles and characterization." Thesis, Toulouse 3, 2016. http://www.theses.fr/2016TOU30211/document.
Повний текст джерелаThis Thesis raises the question of collective decision making under possibilistic uncertainty. We propose several collective qualitative decision rules and show that in the context of a possibilistic representation of uncertainty, the use of an egalitarian pessimistic collective utility function allows us to get rid of the Timing Effect. Making a step further, we prove that if both the agents' preferences and the collective ranking of the decisions satisfy Dubois and Prade's axioms (1995, 1998) and some additional axioms relative to collective choice, in particular Pareto unanimity, then the egalitarian collective aggregation is compulsory. The picture is then completed by the proposition and the characterization of an optimistic counterpart of this pessimistic decision rule. Our axiomatic system can be seen as an ordinal counterpart of Harsanyi's theorem (1955). We prove this result in a formalism that is based on Von NeuMann and Morgenstern framework (1948) and compares possibilisitc lotteries. Besides, we propose a first attempt to provide a characterization of collective qualitative decision rules in Savage's formalism; where decisions are represented by acts rather than by lotteries. From an algorithmic standpoint, we consider strategy optimization in possibilistic decision trees using the decision rules characterized in the first part of this work. So, we provide an adaptation of the Dynamic Programming algorithm for criteria that satisfy the property of monotonicity and propose a Multi-Dynamic programming and a Branch and Bound algorithm for those that are not monotonic. Finally, we provide an empirical comparison of the different algorithms proposed. We measure the execution CPU times that increases linearly according to the size of the tree and it remains affordable in average even for big trees. Then, we study the accuracy percentage of the approximation of the pertinent exact algorithms by Dynamic Programming: It appears that for U-max ante criterion the approximation of Multi-dynamic programming is not so good. Yet, this is not so dramatic since this algorithm is polynomial (and efficient in practice). However, for U+min ante decision rule the approximation by Dynamic Programming is good and we can say that it should be possible to avoid a full Branch and Bound enumeration to find optimal strategies

Повний текст джерелаThe goal of this thesis is to analyze the nature and functions of burdens of argumentation, within the context of their relationship with the structure of the legal system and their role in legal reasoning. Such analysis understands law as limited domain, subject to constraints that can be analytically represented by a three-level approach. According to this view, law and legal reasoning are extrinsically, intrinsically and institutionally constrained. In this complex scenario, the argument of this paper is twofold. On the one hand, it claims that burdens of argumentation are necessary components of a legal system that contains rules and principles. On the other hand, by looking at their structure, it claims that these burdens can be understood as effects of rules and standards that establish normative priority relations. On the basis of these analyses, I argue that burdens of argumentation are mechanisms of control and stabilization of the uncertainty that characterizes the suboptimal character of law. First, they make it easier to justify the maintenance in concreto of a preexistent relationship of priority between different principles. Second, they make it harder to invert these relationships of priority. Lastly, burdens of argumentation create stopping points in legal reasoning whenever there is uncertainty about whether the development of new chains of arguments is enough to justify the maintenance or the inversion, in a concrete case, of a given normative relationship of priority.

Повний текст джерелаBy acknowledging the flexible and complex nature of the precautionary principle in EU law, the purpose of this work is to provide a polycentric interpretation of this principle based on diversity rather than uniformity. To achieve this objective, a methodology derived from the methodological pluralism is employed. This allows for the “unitas multiplex” between the different definitions and applications of the precautionary principle to be researched. The core claim is that the polycentric interpretation of the precautionary principle can be built on two concepts: anticipation and action. In the first part of this study, I argue that anticipation implies the qualification by law and the evaluation by science of uncertain risks. In the second part, I consider that, after having anticipated the time of action, decision-makers should act on the basis of the precautionary principle. However, the action undertaken has different meanings and consequences from the procedural and substantive perspective. From the procedural side, the decision-makers have the obligation to take into account this principle, white they remain free on the substantive side, to adopt a precautionary measure

Bahri, Oumayma. "A fuzzy framework for multi-objective optimization under uncertainty." Thesis, Lille 1, 2017. http://www.theses.fr/2017LIL10030/document.
Повний текст джерелаThis thesis is devoted to the study of multi-objective combinatorial optimization under uncertainty. In particular, we address multi-objective problems with fuzzy data, in which fuzziness is expressed by fuzzy triangular numbers. To handle such problems, our main idea is to extend the classical multi-objective concepts to fuzzy context. To handle such problems, we proposed a new Pareto approach between fuzzy-valued objectives (i.e. vectors of triangular fuzzy numbers). Then, an extension of Pareto-based metaheuristics is suggested as resolution methods. The proposed approach is thereafter illustrated on a bi-objective vehicle routing problem with fuzzy demands. At the second stage, we address robustness aspect in the multi-objective fuzzy context by proposing a new methodology of robustness evaluation of solutions. Finally, the experimental results on fuzzy benchmarks of vehicle routing problem prove the effectiveness and reliability of our approach

Повний текст джерелаMany physical signals including audio (music, speech), medical data (ECG, PCG), marine mammals or gravitational-waves can be accurately modeled as a superposition of amplitude and frequency-modulated waves (AM-FM modes), called multicomponent signals (MCSs). Time-frequency (TF) analysis plays a central role in characterizing such signals and in that framework, numerous methods have been proposed over the last decade. However, these methods suffer from an intrinsic limitation known as the uncertainty principle. In this regard, reassignment method (RM) was developed with the purpose of sharpening TF representations (TFRs) given respectively by the short-time Fourier transform (STFT) or the continuous wavelet transform (CWT). Unfortunately, it did not allow for mode reconstruction, in opposition to its recent variant known as synchrosqueezing transforms (SST). Nevertheless, many critical problems associated with the latter still remain to be addressed such as the weak frequency modulation condition, the mode retrieval of an MCS from its downsampled STFT or the TF signature estimation of irregular and discontinuous signals. This dissertation mainly deals with such problems in order to provide more powerful and accurate invertible TF methods for analyzing MCSs.This dissertation gives six valuable contributions. The first one introduces a second-order extension of wavelet-based SST along with a discussion on its theoretical analysis and practical implementation. The second one puts forward a generalization of existing STFT-based synchrosqueezing techniques known as the high-order STFT-based SST (FSSTn) that enables to better handle a wide range of MCSs. The third one proposes a new technique established on the second-order STFT-based SST (FSST2) and demodulation procedure, called demodulation-FSST2-based technique (DSST2), enabling a better performance of mode reconstruction. The fourth contribution is that of a novel approach allowing for the retrieval of modes of an MCS from its downsampled STFT. The fifth one presents an improved method developed in the reassignment framework, called adaptive contour representation computation (ACRC), for an efficient estimation of TF signatures of a larger class of MCSs. The last contribution is that of a joint analysis of ACRC with non-negative matrix factorization (NMF) to enable an effective denoising of phonocardiogram (PCG) signals

Повний текст джерелаUncertainty is immanent in every innovation. Uncertainty about environmental and health risks that surround nanotechnology raises the questions of innovation success. Due in part to a lack of consistent data, there is limited empirical literature on determinants of the diffusion of nanotechnology. As part of a research program on nanotechnology, this research aims to investigate determinants of uptake of innovation in a situation of uncertainty about environmental and health risks. With this goal, as a first step, this work seeks to provide better understanding of the diffusion of a product that has been on the market for a long time. We have chosen a chemical, bisphenol A (BPA), because of the lack of historical data on nanomaterials. As a second step, we compare the results of the BPA study to nanosilver. We apply different econometric methods to gain insights into the relationship between consumption, economic growth, new scientific knowledge about risk and other variables using the data on BPA. The results illustrate a set of factors that influences the consumption of BPA at international level. The comparative study between BPA and nanosilver helps to refine the interpretation of main results and to obtain additional insights into the determinants of uptake of nanosilver. An explanatory analysis sheds light on the actions that different stakeholders undertake in response to new scientific knowledge about risk and deepens our understanding of “nanoresponsible development”.Keywords: Innovation, diffusion of innovation, product life cycle, nanotechnology, bisphenol A, risk, uncertainty, environment, health, precautionary principle, Safer by Design, responsible development

O estudo do buraco negro acústico, ou análogo acústico, se assemelha ao gravitacional da seguinte forma: verifi ca-se o fenômeno da radiação Hawking, apresença de um horizonte de eventos, a possibilidade de se calcular a sua temperatura, também chamada de temperatura Hawking, e obtêm-se uma métrica que descreve a geometria do buraco negro. Inserimos na métrica acústica a teoria não-comutativa, a fim de vericar as correções que resultam desta teoria. Neste trabalho, consideramos o princípio da incerteza generalizado, no formalismo de tunelamento via método de Hamilton-Jacobi, para determinar a temperatura Hawking e a entropia quântica corrigida para buracos negros acústicos não comutativo sem 2+1 dimensões. Em nossos resultados obtemos uma entropia de área, comum termo de correção logarítmica em ordem dominante um termo, em ordem menor, proporcional à temperatura de radiação associada com os buracos negros acústicos comutativos e um termo extra que depende de uma carga conservada. Assim, como no caso gravitacional, não há necessidade de apresentar o corte ultravioleta e as divergências são eliminadas.
Acoustic black hole study resembles the gravitational black hole as follows: we verify Hawking radiation phenomenon the presence of an event horizon, the possibility to calculate its temperature, also known as Hawking temperature, and we obtain a metric that describes the black hole geometry. We insert in the acoustic metric theory the non commutative theory in order to verify the corrections that result from this theory. In this study, we consider the generalized uncertainty principle in tunneling formalism by Hamilton-Jacobi method to determine Hawking temperature and quantum entropy corrected for non commutative acoustic black holes in 2+1 dimensions. In our results, we obtain an entropy are a with a termoflogarith mic correction in ruling order a termina smaller order, proportional to the radiation temperature associated with the commutative acoustic black holes and an extra term that depends on a conserved charge. Thus as in the gravitational case, there is noneed to present the ultraviolet cut-off and differences are eliminated.
Haberstich, Cécile. "Adaptive approximation of high-dimensional functions with tree tensor networks for Uncertainty Quantification." Thesis, Ecole centrale de Nantes, 2020. http://www.theses.fr/2020ECDN0045.
Повний текст джерелаUncertainty quantification problems for numerical models require a lot of simulations, often very computationally costly (in time and/or memory). This is why it is essential to build surrogate models that are cheaper to evaluate. In practice, the output of a numerical model is represented by a function, then the objective is to construct an approximation.The aim of this thesis is to construct a controlled approximation of a function while using as few evaluations as possible.In a first time, we propose a new method based on weighted least-squares to construct the approximation of a function onto a linear approximation space. We prove that the projection verifies a numerical stability property almost surely and a quasi-optimality property in expectation. In practice we observe that the sample size is closer to the dimension of the approximation space than with existing weighted least-squares methods.For high-dimensional approximation, and in order to exploit potential low-rank structures of functions, we consider the model class of functions in tree-based tensor formats. These formats admit a multilinear parametrization with parameters forming a tree network of low-order tensors and are therefore also called tree tensor networks. In this thesis we propose an algorithm for approximating functions in tree-based tensor formats. It consists in constructing a hierarchy of nested subspaces associated to the different levels of the tree. The construction of these subspaces relies on principal component analysis extended to multivariate functions and the new weighted least-squares method. To reduce the number of evaluations necessary to build the approximation with a certain precision, we propose adaptive strategies for the control of the discretization error, the tree selection, the control of the ranks and the estimation of the principal components

Повний текст джерелаChemical substances have become an inextricable feature of the late-industrial society, deemed necessary for the welfare, technological development and economic growth that large parts of the world have come to expect. In Sweden, the identification in the 1960s and 1970s of DDT, PCB and mercury as serious environmental threats led to the establishment of a system of chemicals control which is widely held to be one of the most advanced in the world. The thesisexamines this control system, its possibilities, its problems and its logic, through text analysis of state reports, governmental propositions, the reports of the Swedish Environmental Protection Agency (SEPA) and the Swedish Chemicals Agency (SCA), and interviews with employees at these agencies. The analysis shows chemicals control in Sweden to be a system pervaded with contradictions, which may be explained by an epistemological paradox at its core: that the accumulation of knowledge only serve to increase uncertainty. The constant increase of chemicals production, in combination with the highly unpredictable character of chemicals in the environment, puts the monitoring agencies in an impossible situation, always working against the tide. The thesis also shows, however, that the agencies are themselves an important part of maintaining a system of control that is to a large extent simulated. This in the sense that the system, by its very existence as well as by the circulation of regulatory concepts and principles within it which are in fact without much substance, always signals control, and constitute uncertainty as the exception.

Повний текст джерелаIntroduction - Since the 1970s, the society at large has been faced with unprecedented risks and uncertainties. Landmark cases in the health, safety and environmental areas have been extensively debated by the media, nongovernmental organizations, governments, corporations and the civil society as a whole, and the law has been called upon to take a stance over these issues. To cope with these issues, international and environment law has devised, over the last two decades, the so-called precautionary principle. Scope - This research seeks to draw a distinction between what the precautionary principle has been from what it is not, and what it may come to be, thus contributing to studies on the legal realms of the Risk Society and the relations between the law and uncertainties. Bibliography - This study has primarily relied on French literature covering the precautionary principle, international case law, and the recent initiatives of both the European Union and the World Health Organization. Brazilian case law, legal writings and laws have also been taken into consideration. Aspects - This work addresses the framework of Risk Society and how environmental law relates to its scientific aspects. Then, the consolidation of such principle on its ethical and legal fronts was studied. As current (and rather debatable) themes are into play, the application of Risk Society is still controversial, but the difficulties faced by such application and the criticism directed at it help understand the potential characteristics of this framework. Conclusion - In Brazil, understanding what the precautionary principle stands for (or even what it does not) is still incipient. Brazilian courts make a confusion between precaution and prevention: the precautionary principle is taken as a synonym for a general duty to conserve the environment or as a reason for limitations. A deeper understanding of this precautionary principle calls for a greater awareness of its theory and practice. Applying the precautionary principle should thus be grounded on risk analyses; on the adoption of standards that are capable of governing its practice; and on effective use of legal standards. The controversy over the precautionary principle has invited to a more reflective approach to science, while also strengthening (within the realms of law, and beyond) decision-making efforts involving the public opinion and the scientific community.

Survey indicators produced by FGV are economic information published relatively quickly and used as a 'thermometer' of the Brazilian level of activity in the short term. The use of the Consumer Confidence Index (CCI), as well as other indicators within the survey, are taken as a antecedent or coincident in household consumption forecasting models and other official quantitative variables. However, the work seeks to show evidence that information at the aggregate level has not always the best predictive power. The work seeks to analyze the behavior of consumers under a more disaggregated view of the research in order to obtain greater correlation and robustness with the target variables. There is evidence that some consumer groups are able to provide better assessments on one topic than others. Using the Principal Component Analysis (PCA), we reduce the dimensionality of these better indicators to obtain robustness in the forecasting scenarios. To complement these predictions, we will use the indicator of dispersion of responses as an uncertainty proxy, in an attempt to understand subjectivity of survey data. The conclusion of the article is given through the analysis of the stylized facts of the behavior of these groups selected for each case.
Indicadores de sondagens produzidas pela FGV são informações econômicas divulgadas de forma relativamente rápida e utilizadas como 'termômetro' do nível de atividade brasileira no curto prazo. A utilização do ICC (Índice de Confiança do Consumidor), assim como outros indicadores por dentro da sondagem, são tidas como antecedente ou coincidente em modelos de previsão do consumo das famílias e para as demais variáveis quantitativas oficiais. No entanto, o trabalho procura mostrar evidências de que nem sempre as informações ao nível agregado, possuem o melhor poder preditivo. O trabalho busca analisar o comportamento dos consumidores sob uma ótica mais desagregada da pesquisa a fim de obter maior correlação e robustez com as variáveis target. Existem evidências de que alguns grupos de consumidores conseguem fornecer melhores avaliações sobre determinado tema do que outros. Utilizando a técnica de componentes principais, extraímos o núcleo destes melhores indicadores desagregados para obter robustez nos cenários de previsão. Para complementar estas previsões, utilizaremos o indicador de dispersão das respostas como uma proxy de incerteza, na tentativa de compreender o lado subjetivo intrínseco às pesquisas de sondagem. A conclusão do artigo se dá através da análise dos fatos estilizados do comportamento destes grupos selecionados para cada caso.
