O método multicritério PROMETHEE V possui uma abordagem voltada para seleção de portfólios, porém possui problemas devido às suas transformações de escala, distorcendo o resultado. Foi testado então um modelo que utiliza o conceito de portfólios c-ótimos, para eliminar tais distorções devido a mudanças de escalas. O modelo baseado no PROMETHEE V com conceitos de portfólios c-ótimos foi aplicado a um problema realístico, sendo realizada também uma análise de robustez sobre o resultado. Foram verificadas, porém, distorções oriundas do próprio método PROMETHEE V. Uma análise aprofundada do método mostrou uma fonte destas distorções, oferecendo uma prova matemática da inadequação do PROMETHEE V. Um novo modelo foi proposto, como alternativa que utiliza a racionalidade não-compensatória do PROMETHEE sem apresentar as distorções verificadas no PROMETHEE V, para encontrar a solução do problema. O novo modelo aplica o método PROMETHEE II sobre os portfólios ao invés de projetos, para isto foi utilizado um procedimento de geração de portfólios de fronteira descrito na literatura, realizando sobre este procedimento uma adaptação que aumenta a sua eficiência. O novo modelo proposto foi aplicado a problemas simulados, sendo feita uma comparação que mostra que sua recomendação supera e podendo inclusive dominar a recomendação do modelo com PROMETHEE V. / This work presents a methodology for selection of information system portfolios that integrates the strategic view of the organization to the IS planning. The multi-criteria method PROMETHEE V has an aproach that aims the portfolio selection, but it has problems due to its changes in scale that distorts the result. A model that uses the concept of c-optimo portfolios has been tested then, in order to eliminate these distortions caused by changes in scale. The PROMETHEE V with the c-optimo portfolio concept has been used in a realistic problem, an analysis of robustness has also been done. However, distortions from the PROMETHEE V method have been verified. A deep analysis of the method has showed a source of these distortions, offering a mathematical proof of the PROMETHEE V inadequacy. A new model has been proposed as an alternative that uses the non compensatory rationality of the PROMETHEE, without presenting the distortions verified on the PROMETHEE V, in order to find solutions to the problem. The new model applies the PROMETHEE II methodon the portfolios instead on the projects. With this aim, was used a boundary portfolio generation procedure, described in literature, changing this procedure to increase its efficiency. The new model proposed was applied to simulated problems, and in a comparison of results, its recommendation was better and even dominates the PROMETHEE V recommendation.

Neste trabalho, ele é resolvido com a devida consideração das restrições de fluxo de intercâmbio energético entre os subsistemas em um único modelo. Para tanto, fez-se necessária a representação explícita do balanço energético, definido como a soma das gerações hidro e termelétrica e do intercâmbio líquido, tal que a demanda de carga seja atendida. As dificuldades algébricas e computacionais impostas pela formulação do problema são contornadas por meio de um método de pontos interiores primal-dual não-linear. Nele, é empregada busca unidimensional com filtro que, dada a implementação proposta, apesar de não garantir convergência global, mostrou-se eficaz em todas as instâncias de testes numéricos realizados, dispensando o uso de funções de mérito. A estrutura esparsa bloco-diagonal das restrições do problema é explorada com vistas à obtenção de melhor desempenho computacional. Resultados dos estudos de caso numéricos para dados reais do sistema elétrico brasileiro sob diferentes configurações são apresentados. / Abstract: This work presents the solution of the medium-term operation scheduling problem for hydrothermal power systems, a complex large-scale nonlinear problem, with consideration of power exchange between interconnected systems. This required the need to explicitly represent the power balance nonlinear equations, defined as the sum of hydro and thermal outputs, and net power imports such that load demand is attained. Algebraic and computational difficulties arisen by the problem formulation are overcome by the use of a nonlinear primal-dual interior-point line search filter method. A line search filter procedure is chosen for these are known to generally outperform penalty merit functions. Although the implementation proposed herein does not guarantee global convergence, it has shown to be very efficient for all numerical tests performed. In addition, the problem's block-constraint structure is exploited for means of improved computational efficiency. Results for diverse numerical tests applied to the Brazilian power system are shown. / Doutorado / Energia Eletrica / Doutor em Engenharia Elétrica

O PET é um problema de grande extensão, inteiro misto, não linear, e não convexo. Portanto, mais técnicas de otimização devem ser investigadas para resolvê-lo de forma eficiente. Neste trabalho de pesquisa, o foco do estudo foi a metaheurística de otimização por enxame de partículas (PSO) aplicada ao problema PET estático. Os desempenhos das variantes Global (GPSO) e Local (LPSO) são comparados com quatro novas variantes do PSO baseado no comportamento quântico de otimização por enxame de partículas (QPSO). QPSO considera um comportamento quântico dos movimentos de partículas, de acordo com a mecânica quântica, que, em teoria, levaria a uma melhor convergência global do que o tradicional PSO. Esta pesquisa utiliza o modelo DC das redes de potência, considerando restrições de segurança usando o critério . Os conhecidos sistemas Garver, IEEE de 24 barras, e equivalente sul brasileiro de 46 barras são usados para apresentar os resultados deste trabalho de pesquisa / Abstract: The Transmission Expansion Planning (TEP) consists of determining all the changes needed in the transmission system infrastructure, i.e. additions and reinforcements, in order to allow the balance between the projected demand and the power supply, at minimum investment along the planning horizon. The TEP is a large scale, mixed-integer, non-linear and non-convex problem. Therefore more optimization techniques must be investigated to solve it in an efficient way. In this research work, the focus was on the study of the optimization metaheuristics by particle swarm (PSO) applied to the static version of the TEP problem. The performances of the Global (GPSO) and Local (LPSO) variants are compared against four new PSO variants based on the Quantum-behaved Particle Swarm Optimization (QPSO). QPSO considers a quantum behavior of particles' movements, according to quantum mechanics, which in theory would lead to a better global convergence than traditional PSO. This research uses the DC model for the network and takes into account security constraints using the well-known criterion. The well-known Garver, IEEE 24-bus, and the 46-bus Southern Brazilian equivalent networks will be used to present the results of this research work / Mestrado / Energia Eletrica / Mestre em Engenharia Elétrica

Propostas para a construção da matriz de energia elétrica brasileira com foco na sustentabilidade do processo de expansão da oferta e segurança no suprimento da carga / Proposals for the construction of the Brazilian electric power matrix with focus on the sustainability of the expansion process and the security of supply

Dester, Mauricio 21 August 2018 (has links)
Orientadores: Sérgio Valdir Bajay, Moacyr Trindade de Oliveira Andrade / Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecânica / Made available in DSpace on 2018-08-21T11:31:07Z (GMT). No. of bitstreams: 1 Dester_Mauricio_D.pdf: 5389676 bytes, checksum: 7c5e6ad30bbd780ddf1b9300f7cc4317 (MD5) Previous issue date: 2012 / Resumo: A eletricidade é bem de consumo e também insumo posicionado dentre aqueles considerados essenciais para a sociedade moderna. Neste contexto, o planejamento e a construção de uma matriz de energia elétrica é questão de importância capital não somente para o setor elétrico, como também para o desenvolvimento do Brasil. A constituição desta matriz deve ser pautada, sobretudo, pelo aspecto sustentabilidade. Neste sentido, sua concepção deve, imprescindivelmente, contemplar todas as perspectivas que permeiam o processo estratégico que a origina, a saber: técnica, econômica e sócio-ambiental. Somente balizado por estas óticas é possível proporcionar a expansão da oferta de energia elétrica de forma sustentável e com segurança no que concerne ao atendimento pleno da demanda, um requisito indispensável para que este serviço possa ser um sólido sustentáculo de um processo maior: o desenvolvimento socioeconômico da sociedade brasileira. A participação das fontes renováveis na matriz de energia elétrica é fator desejável e colabora, de forma meritória no que diz respeito aos impactos ambientais decorrentes da produção de eletricidade. Todavia, há algumas questões de ordem econômica e principalmente técnica as quais devem ser tratadas e lapidadas de forma a eliminar as lacunas existentes, permitindo que se possa estabelecer planos de expansão da oferta de eletricidade sustentáveis sob todos os pontos de vista. O objetivo principal deste trabalho é proporcionar e aprofundar o debate sobre estas questões e apresentar uma solução que propicie a integração das fontes renováveis na matriz de energia elétrica brasileira mantendo a confiabilidade no atendimento da carga. Outrossim, não somente os aspectos técnico e econômico foram contemplados na análise, mas, também o socioambiental, possibilitando assim oferecer subsídios para a evolução da oferta com orientação para a sustentabilidade. Para elaboração da proposta foi realizado um estudo abrangente sobre as principais fontes primárias a partir das quais é possível produzir eletricidade, além de uma revisão de todo o extenso e complexo caminho pelo qual passou o setor de planejamento da expansão desde seus primórdios até o modelo atual. São também apresentados vários pontos de vista sobre as dificuldades encontradas pelo planejador, desde os empecilhos de ordem regulatória, passando por aqueles oriundos de uma falta de coordenação dentre os setores do governo envolvidos no problema, até as questões de ordem ambiental. Por fim, no decorrer do trabalho e particularmente ao concluí-lo, propõe-se um conjunto de medidas estratégicas por intermédio das quais se pode construir uma matriz de energia elétrica segura e sustentável e lograr êxito, sob as perspectivas técnica, econômica e socioambiental, ao se realizar o planejamento da expansão da oferta, seja no horizonte de curto, médio ou longo prazos / Abstract: Electricity is not just a consumer good but also an input which commands a place amongst those goods considered essential to modern society. In this context, the planning and construction of an electricity matrix is a question of paramount importance, not just for the electricity sector but also for Brazil's development as a whole. The establishment of this matrix should, above all, be regulated with an emphasis on sustainability. In this regard, its conception must necessarily embrace all the perspectives that imbue the strategic process that gives rise to it: technical, economic and socio-environmental. Delimited by these viewpoints alone, it is possible to provide the sustainable expansion of an electric power supply that is also secure in terms of being able to fully meet demand. This is a fundamental prerequisite to this service becoming a solid base for a larger process, namely the socio-economic development of Brazilian society. The participation of renewable energy sources in the electric energy matrix is a desirable factor and contributes laudably to the mitigation of environmental impacts resulting from the electricity generation. Nevertheless, there are several issues of an economic and mainly technical nature which have to be dealt with and refined in order to close the existing gaps and enable plans to be established, that are sustainable from all points of view, for the expansion of an electric power supply. The main aim of this study is to prompt, and study in greater depth, the debate over these issues and present a solution that delivers the integration of renewable sources into Brazil's electricity matrix while maintaining reliability of load fulfillment. Similarly, not only were the technical and economic aspects covered in the analysis but also the socio-environmental aspects, thereby making it possible to provide support for the evolution of a sustainability-oriented supply. For the purposes of drafting this proposal, a wide-ranging study was conducted of the principal primary sources from which it is possible to generate electricity, as well as a review of the long and complex path which the expansion planning sector has taken, from its outset through to the current model. Various points of view are also put forward about the difficulties encountered by the planner, ranging from the regulatory obstacles to those arising from a lack of coordination between the government sectors involved in the problem and to issues of an environmental nature. Finally, throughout the study and in particular in its conclusion, a set of strategic measures is proposed through which a secure, sustainable electricity matrix can be constructed from a technical, economic and socio-environmental perspective, which is successful in carrying out supply expansion planning in the short, medium and long term / Doutorado / Planejamento de Sistemas Energeticos / Doutor em Planejamento de Sistemas Energéticos

Urban Planning & Governance in the Age of AI : A Study of the Potential Benefits and Risks / Stadsplanering och styrning i AI-tidsåldern : En studie om potentiella fördelar och risker

Gummesson, Jonas January 2023 (has links)
Artificial intelligence (AI) is a rapidly developing technology which in this project refers to software that given objectives generate content, predictions, recommendations, or decisions influencing their environment. Using literature reviews and semi-structured interviews, the current and future uses, sentiments, regulations, and risks of AI in urban planning and governance are gathered. While current uses are few, the potential capabilities range from highly complex and large-scale, to small-scale and routine tasks. These tasks include smart resource management, predictive analysis, digital personal assistance, intelligent data processing, and visualization and recommendation. The general goal is to better reinvest human time and effort, for instance in providing meaningful citizen interactions. A lack of good governance and regulation of AI could permit profit-driven technology companies to control the discourse, possibly contributing to issues of public trust, lack of transparency and accountability, inequality, and public participation. Organisations and nations including the UN, EU, and Sweden have formulated strategies for AI, and the EU is currently developing the first regulatory framework for AI facilitating the protection of good operation, design, inclusivity, and privacy of the systems. Further research and debate on this topic is needed to ensure that AI is developed, implemented, and used ethically and responsibly. / Artificiell intelligens (AI) är en snabbt utvecklande teknologi som i detta projekt avser programvara som med givna mål genererar innehåll, förutsägelser, rekommendationer eller beslut som påverkar dess omgivning. Genom litteraturöversikter och semistrukturerade intervjuer har de aktuella och framtida användningsområdena, åsikterna, regleringarna och riskerna med AI inom stadsplanering och styrning samlats in. Trots att de nuvarande användningsområdena är få sträcker sig de potentiella förmågorna från mycket komplexa och storskaliga till småskaliga rutinuppgifter. Dessa uppgifter inkluderar smart resurshantering, prediktiv analys, digital personlig assistans, intelligent databehandling samt visualisering och rekommendation. Det övergripande målet är att investera mänsklig tid och ansträngning på ett bättre sätt, exempelvis genom att erbjuda meningsfulla interaktioner med medborgare. En brist på god styrning och reglering av AI skulle kunna tillåta vinstdrivna teknikföretag att kontrollera diskursen, vilket kan leda till problem med allmänhetens förtroende, brist på transparens och ansvar, ojämlikhet och offentlig delaktighet. Organisationer och nationer inklusive FN, EU och Sverige har formulerat strategier för AI, och EU utvecklar för närvarande det första regelverket för AI för att underlätta god drift, utformning, inkludering och integritet hos systemen. Ytterligare forskning och debatt om detta ämne behövs för att säkerställa att AI utvecklas, implementeras och används på ett etiskt och ansvarsfullt sätt

Strategic Information Systems Planning (SISP) in the banking sector: An Investigation of Strategic Information Systems Planning (SISP) in the Saudi Banking Sector

Al-Faidi Al-Juhani, Mohammed H. January 2011 (has links)
The improvement of SISP practices has rapidly become one of the most critical issues facing many organisations, including banks. Globally, the banking sectors, including the Saudi one, have developed and implemented many IS strategies. Several systems have been executed to support the countries’ economies which have benefited from the increased trading resulting from the greater flexibility in time and costs associated with banking transactions. To continue these achievements and to improve SISP processes, several factors require careful investigation based on their relationship to SISP success; which include SISP objectives, SISP internal factors, external consultant functions, SISP external factors, measurements of SISP success, key stakeholders’ roles, and triggers. Therefore this study investigates the impact of these factors on SISP success. Data were collected in three phases. Phase 1 was an initial study with one or two interviews with the IT directors of each bank in the Saudi banking sector comprising the central bank and 11 commercial banks. The outcomes informed the development of a survey that was used in Phase 2; to investigate a sample containing a central bank, a domestic commercial bank and a domestic-foreign commercial bank to determine their SISP processes. 157 completed questionnaires were returned from the bank executives, business and IT directors and consultants. In Phase 3, 57 interviews confirmed and explained the quantitative results from Phase 2. Therefore, an in-depth case study was made in the three banks during Phases 2 and 3. The research results support previous findings on the SISP’s seventeen objectives collected by several researchers across different industries and in various countries. Furthermore, the research condenses these seventeen objectives into five more practical and achievable objectives for the banking sector. These are: 1) planning and deployment of information systems; 2) leading organisation changes; 3) improving stakeholders’ involvement and communication; 4) achieving the strategic priorities; and 5) alignment of organisational policies and architecture for business and IS. In addition, the findings identify the factors according to their relationship with SISP success and therefore explore several elements with positive, negative or no impact on SISP success in the banking sector. The thesis presents conclusions and suggests areas for further research.

Methodology for the optimal management design of water resources system under hydrologic uncertainty

Haro Monteagudo, David 12 January 2015 (has links)
Un sistema de gestión de sequías apropiado requiere de la anticipación de los posibles efectos que un episodio de este tipo tenga sobre el sistema de recursos hídricos. Esta tarea sin embargo resulta más complicada de lo que parece. En primer lugar, debido al alto grado de incertidumbre existente en la predicción de variables hidrológicas futuras. Y en segundo, debido al riesgo de sobrerreacción en la activación de medidas de mitigación generando falsa sensación de escasez, o sequía artificial. A este respecto, los planes especiales de sequía proveen de herramientas para la gestión eficiente de situaciones con escasez de recursos y la preparación de cara a futuros eventos. De todos modos, las diferentes estrategias de operación seguidas en cada sistema de recursos hídricos hacen que las herramientas que en algunos casos resultaron altamente útiles no lo sean tanto cuando se aplican en sistemas distintos. Debido a la falta de tiempo y/o al exceso de confianza en los trabajos realizados por terceros, con excelentes resultados en sus respectivos casos, a veces se cae en el error de implementar metodologías no del todo apropiadas en sistemas con requisitos completamente distintos. El desarrollo y utilización de metodologías generalizadas aplicables a diferentes sistemas y capaces de proporcionar resultados adaptados a cada caso es, por tanto, muy deseable. Este es el caso de las herramientas de modelación de sistemas de recursos hídricos generalizadas. Estas permiten homogeneizar los procesos mientras siguen siendo los suficientemente adaptables para proporcionar resultados apropiados para cada caso de estudio. Esta tesis presenta una serie de herramientas destinadas a avanzar en el análisis y comprensión de los sistemas de recursos hídricos, haciendo énfasis en la prevención de sequías y la gestión de riesgos. Las herramientas desarrolladas incluyen: un modelo de optimización generalizado para esquemas de recursos hídricos, con capacidad para la representación detallada de cualquier sistema de recursos hídricos, y una metodología de análisis de riesgo basada en la optimización de Monte Carlo con múltiples series sintéticas. Con estas herramientas es posible incluir tanto la componente superficial como la subterránea del sistema estudiado dentro del proceso de optimización. La optimización está basada en la resolución iterativa de redes de flujo. Se probó la consistencia y eficiencia de diferentes algoritmos de resolución para encontrar un balance entre la velocidad de cálculo, el número de iteraciones, y la consistencia de los resultados, aportando recomendaciones para el uso de cada algoritmo dadas las diferencias entre los mismos. Las herramientas desarrolladas se aplican en dos casos de estudio reales en la evaluación y posibilidad de complementación de los sistemas de monitorización y alerta temprana de sequías existentes en los mismos. En el primer caso, se propone un enfoque alternativo para la monitorización de la sequía en el sistema de operación anual del río Órbigo (España), complementándolo con la utilización de la metodología de análisis de riesgo. En el segundo caso, las herramientas se emplean en un sistema con una estrategia de operación completamente distinta. Se estudia como el análisis de riesgo de la gestión óptima puede ayudar a la activación anticipada de los escenarios de sequía en los sistemas de los ríos Júcar y Turia, cuya operación es hiperanual. En esta ocasión, el sistema de indicadores existente goza de una gran confianza por parte de los usuarios. La metodología de análisis de riesgo es, sin embargo, capaz de anticipar los eventos de sequía con mayor alarma, aspecto que es deseable si se quiere evitar que los episodios en desarrollo vayan a más. En ambos casos se muestra como la evaluación anticipada de las posibles situaciones futuras del sistema permiten una definición confiable de los escenarios de sequía con suficiente antelación para la activación efectiva de medidas de prevención y/o mitigación en caso de ser necesarias. La utilización de indicadores provenientes de modelos frente a indicadores basados en datos observados es complementaria y ambos deberían utilizarse de forma conjunta para mejorar la gestión preventiva de los sistemas de recursos hídricos. El empleo de modelos de optimización en situaciones de incertidumbre hidrológica es muy apropiado gracias a la no necesidad de definir reglas de gestión para obtener los mejores resultados del sistema, y teniendo en cuenta que las reglas de operación habituales pueden no ser completamente adecuadas en estas ocasiones. / Haro Monteagudo, D.
