We investigate the use of the concept of indiscernibilityand vagueness in spatial information systems. To representindiscernibility and vagueness we use rough sets, respectivelyfuzzy sets. We introduce a theoretical model to supportapproximate queries in information systems and we show howthose queries can be used to perform uncertain classi.cations.We also explore how to assess quality of uncertainclassi.cations and ways to compare those classi.cations to eachother in order to assess accuracies. We implement the querylanguage in an SQL relational language to demonstrate thefeasibility of approximate queries and we perform an experimenton real data using uncertain classi.cations.

Poverty analysis in fisheries is dominated by assumptions of a linear relationship between fishing, income and poverty. Poverty is seen as a function of income, and income as a function of fish catch. Thus, the analytical frameworks to understand poverty in fisheries, and the policies enacted to reduce it, have focused on issues of overexploitation, regulatory mechanisms to maximize rent extraction, and technological innovation to improve fisheries’ productivity. This set of relations is underpinned by the assumption that improving fish catch per se would reduce fishers’ poverty. The study of fishing livelihoods on Lake Kossou in Côte d’Ivoire problematizes some of these assumptions. I revisit the “essentialization” of fishers with fish by utilizing the Sustainable Livelihood Approach as a lens of analysis, and by demonstrating that fishers’ livelihoods are based on a diversified portfolio of activities that span multiple sectors. Looking at livelihoods also questions the validity of the conventional “sites” of poverty analysis in fisheries (i.e. the boat, the landing site) and how these lead to misrepresentations of fishers’ livelihoods by emphasizing the upstream elements (catches) to the detriment of downstream activities in the value chain (processing and trading) that are crucial in the realization of fishers’ sustainable livelihoods. Looking at the complexity of fishers’ livelihoods sheds light on the relations between poverty (as an outcome variable) and vulnerability as a constant condition that is linked to access to multiple types of assets, the institutional contexts in which they operate, and the ways in which access to natural resources is constantly re-negotiated. To that effect, this study shows how access to Lake Kossou took a completely new meaning when the coffee-cocoa economy collapsed and young Ivorians saw it as an opportunity being stolen from them by Malian fishers. The context of post-colonial national identity formation (epitomized in the search for “Ivoirité”) served as political justification for claiming new rights to natural resources that had been relatively unimportant until then in economic terms. Finally, this study provides an innovative approach to poverty analysis by emphasizing its multiple dimensions, and by utilizing the statistical fuzzy sets methodology to construct multidimensional poverty indices.

Orientador: Valério Antonio Pamplona Salomon / Banca: Fernando Augusto Silva Marins / Banca: Carlos Henrique Pereira Mello / Resumo: Nos últimos anos, várias novas plantas industriais para a produção de veículos automotores foram construídas e estão em operação no Brasil. Esse fato, aliado às mudanças estruturais dos fabricantes em todo o mundo, gerou novas relações entre as montadoras e seus fornecedores de autopeças. As montadoras adotaram um processo de delegação produtiva junto a seus fornecedores. Lançada em 1999, a ISO/TS 16949 tem como objetivo atender aos requisitos normativos das principais montadoras americanas, alemãs, francesas e italianas. Entre estes requisitos tem-se o desenvolvimento e revisão de análises do modo e efeito de falha (FMEA, Failure Mode and Effect Analysis) para a aplicação em desenvolvimento de projetos de produtos e processos de manufatura. Mesmo com um formulário semelhante a um roteiro, o preenchimento de um FMEA de processo é uma atividade complexa, na qual as relações entre as colunas e os critérios de pontuação adotados são de vital importância para o seu desempenho. Em muitos casos o FMEA é usado mais por exigências normativas do que por seus benefícios, sendo que o seu incorreto emprego pode acarretar em desperdício de recursos. Tendo um foco em empresas do setor automotivo, o presente estudo visa apresentar uma proposta para a avaliação do desempenho da aplicação do FMEA de processo, identificando as irregularidades que ocorrem em seu uso, de forma a hierarquizá-las de acordo com a gravidade e obtendo uma sistemática de avaliação de cada caso. Para tanto, foi realizado um embasamento teórico sobre a aplicação de FMEA de processo associado a um estudo de caso para avaliação do uso do FMEA nas organizações selecionadas pela aplicação da metodologia de auxílio à decisão. / Abstract: In recent years, new several industrial plants for the vehicles production were built and are in operation in Brazil. That fact, added to the global changes in the automotive production, generated new relationships between the assembly plants and their suppliers, that it resulted in the adoption of a process of productive delegation with the manufacturers of automotive parts. Maid in 1999, ISO/TS 16949 has as objective assists to the normative requirements of the main American, Germans, French and Italian assembly plants. Among these requirements there is the development and revision of analyses in the mode and faulire effect (FMEA, Failure Mode and Effect Analysis) for the application in development of projects of products and manufacture processes. Even with a form similar to an itinerary, the completion of a process FMEA is a complex activity, which the relationships between the columns and the punctuation criteria adopted are very important for its performance. In many cases FMEA is used more by normative demands than for their benefits, and its incorrect job can result in resources waste. With a focus in companies of the automotive section, this study seeks to present a proposal for the evaluation of the of Process FMEA application, identifying the irregularities that happen in its use, in way the hierarchy in agreement with the gravity and obtaining a systematic of evaluation of each case. For that, a theoretical rising was accomplished about the application of process FMEA associated to a case study for evaluation of FMEA aplication in the selected organizations by the application of the decision-making methodology. Specifically will be used the method AHP (Analytic Hierarchy Process) and the Fuzzy Sets, which, starting from the literature, the fundamental concepts are discussed associates to the theory of this methods. / Mestre

No Capítulo II, foi realizada uma pesquisa bibliográfica quanto ao processo evolutivo da legislação ambiental brasileira e de Sorocaba quanto à reserva de espaços verdes e áreas livres no processo de parcelamento do solo no ambiente urbano. No Capítulo III, foi construído com auxílio da teoria dos conjuntos fuzzy um modelo para analisar os estágios de sucessão florestal em fragmentos florestais. Considerando que a vegetação florestal exerce forte influência nos serviços ecossistêmicos urbanos. O Capítulo IV tem por objetivo, propor um modelo de avaliação dos fragmentos florestais urbanos que possa refletir sua capacidade em contribuir com os serviços ecossistêmicos urbanos. O modelo foi constituído com uso da Teoria dos Conjuntos Fuzzy. Para testar o modelo, foram utilizados parâmetros de loteamentos aprovados e implantados no município de Sorocaba, SP, Brasil.

As a way to discuss this issue in chapter I of this work was performed a literature review in order to understand how science understands the action of urban vegetation in the process of enhancing ecosystem services. In chapter II a bibliographical research as to the evolutionary process of the brazilian environmental legislation and of Sorocaba how to green spaces and open areas in the process of subdivision of the soil in urban environment. In chapter III was built with the aid of fuzzy set theory a model to analyze the stages of forest succession in forest fragments. Whereas the forest vegetation exerts strong influence on ecosystem services. Chapter IV aims to propose a model for the evaluation of urban forest fragments that can reflect your ability to contribute to ecosystem services. The model was constituted with use of Fuzzy set theory. To test the model, approved building lots parameters were used and deployed in the municipality of Sorocaba, SP, Brazil. The result proved to be efficient in your purpose. The system proved serve as auxiliary tool in the decision-making process for approval of projects and can help improve decisions of public managers and improve the process of occupation of urban land. / Doutor
