The main purpose of this thesis was the application of the multicriterial decision making options methods on specific decision situations in the public sector. The task was to present the most important methods and to show the possibility of their use in reality. From the methods requiring ordinal information I chose the Cook - Seiford method which can be utilized when the sources are limited. From the cardinal data requiring methods I chose the Weighted Sum Approach method and the AHP method (based on the calculation of values of the utility function), the TOPSIS method (based on the minimization of distance from the ideal option) and the ELECTRE I. method (based on the plotting of the preferential relation).

Conselho Nacional de Desenvolvimento Científico e Tecnológico / Nowadays, the Brazilian electric systems need the development of new researches and tools, in order to obtain a logic solution to maintain and improve the reliability and the quality of the power delivered to customers. Therefore, the study of the appropriate connection of distributed generation sources is an essential topic to be analyzed, since this process may provide positive impacts along the feeders. An appropriate DG site is an important aspect mentioned in the PRODIST (Proceedings of Electric Energy Distribution on Electrical National System), inside section 3. For now, the PRODIST is just an orientating tool established by the ANEEL - National Regulatory Agency of Electric Energy. It is important to observe that after the approval of PRODIST, this tool will be the standard for several processes considering planning and operation of distribution systems in Brazil. During the development of this work the main types of distributed energy sources were presented in order to observe their characteristics and their applications on distributions networks. Besides, the main effects of the DG operation inside three distribution system models were analyzed through the software DigSilent®, considering power losses and voltage levels. Moreover, this study intends to perform a multi-objective analysis defining some quantitative and qualitative parameters evaluated by specific softwares, according to the types of parameters. It is important to emphasize that the appropriate choice of these parameters is essential to support the final results, since a wrong choice or a lacking of an import parameter may provide undesirable outputs. These parameters were applied on the Bellman-Zadeh algorithm and the membership fuzzy functions, in order to find the appropriate DG site inside a distribution system model. These two methods are described separately. However, the methods are applied on a practical example together. Therefore it is possible to analyze the main characteristics of each method, emphasizing its applications on the multi-objective analysis. The developed methodology intends to provide positive effects in distribution networks and also work towards the planning of distribution systems. It is important to observe that the methodology presented in this study may be applied to distribution system feeders to find in which feeder will be the most appropriate DG location, and to any node inside a determined feeder providing a specific place for the appropriate DG site. / Avaliando o momento atual do setor elétrico brasileiro, percebe-se a crescente necessidade de se encontrar novos caminhos para o avanço dos setores de distribuição de energia elétrica. Desta forma a inserção de fontes de geração distribuída (GD) apresenta-se como uma alternativa estratégica para o desenvolvimento do sistema energético brasileiro. A adequada localização das fontes de GD é um importante aspecto citado nos Procedimentos de Distribuição de Energia Elétrica no Sistema Elétrico Nacional (PRODIST) Módulo 3, sendo este um instrumento orientativo criado pela Agência Nacional de Energia Elétrica (ANEEL). Durante o desenvolvimento deste trabalho foram pesquisados os principais tipos de fontes de geração distribuída com o objetivo de avaliar as características e aplicações das mesmas. Além disso, foram observadas as principais conseqüências da conexão de fontes de GD em três protótipos de sistemas de distribuição, considerando perdas de potência e níveis de tensão, simulados através do software DigSilent®. Com base em uma análise multicriterial foram definidos parâmetros quantitativos e qualitativos, avaliados previamente através de softwares específicos para cada tipo de parâmetro. Deve-se observar a importância da correta escolha destes parâmetros, pois a ausência de um único parâmetro, que possua uma elevada importância para o sistema em questão, pode comprometer a validade dos resultados obtidos. Estes parâmetros foram aplicados em uma metodologia utilizando o algoritmo de Bellman-Zadeh e os conjuntos fuzzy, com o objetivo de encontrar a localização mais adequada de uma fonte de geração distribuída em um sistema de distribuição. Estes dois métodos serão descritos separadamente e avaliados de forma conjunta, visando estabelecer suas principais características a suas diferentes aplicações em análises multicriteriais. A metodologia desenvolvida neste estudo visa o correto desenvolvimento dos sistemas de distribuição de média tensão, contribuindo para futuros planejamentos deste sistema. Outro importante fato a ser observado é que a metodologia proposta neste estudo pode ser aplicada tanto na análise de um sistema de distribuição com intuito de determinar qual é o alimentador mais adequado a se instalar a fonte de GD, quanto na análise de determinados alimentadores buscando especificamente qual é o local dentro de cada alimentador onde deve ser instalada a fonte de GD.

[pt] Em um cenário mundial de intensa competição, com indústrias cada vez mais complexas e dinâmicas, a tomada de decisão se tornou um fator chave que muitas vezes pode determinar a sobrevivência e o sucesso de uma empresa. A indústria do petróleo possui investimentos anuais na ordem de bilhões de dólares e por isso toda decisão é considerada vital para esta indústria. Em função da grande quantidade de projetos sendo estudados e propostos, tanto de ampliação quanto de manutenção da estrutura das empresas, do alto valor de cada um e da restrição orçamentária de cada empresa, a tomada de decisão é um passo importante e complexo, devido às inúmeras variáveis e restrições envolvidas. Esta dissertação elabora uma proposta de método de apoio para o processo de tomada de decisão usado na seleção de projetos de investimento em logística de uma grande empresa do setor de óleo e gás. Na maioria das vezes, os critérios utilizados para a tomada de decisão na seleção de projetos consideram apenas os aspectos financeiros, sem levar em consideração outros critérios, que são abordados nesse trabalho. Em função da importância dos projetos e da quantidade de variáveis envolvidas durante a seleção e priorização deles, esse trabalho utiliza o método AHP (Analytic Hierarchy Process) Simplificado e os conceitos de Programação Linear Inteira Mista (PLIM) para determinar os projetos prioritários e otimizar a satisfação do grupo tomador de decisão. Foram estudados seis dos principais projetos da empresa, que juntos somam, aproximadamente, 2,7 bilhões de doláres e representam quase 80 por cento da carteira da área de logística da empresa estudada. Este estudo possibilitou uma seleção mais eficaz, resultando em uma maior integração entre os tomadores de decisão e um maior conhecimento sobre cada um dos projetos avaliados. / [en] In a global scenario of intense competition with increasingly complex and dynamic industries, decision-making has become a key factor that can often determine the survival and success of a company. The oil and gas industry has annual investments of billions of dollars and every decision is considered vital for this industry. Due to the large number of projects being proposed and studied, involving both expansion and maintenance of business structure, the high value of each and the budget constraint of each company, the decision-making is important and complex, due to numerous variables and constraints involved. This dissertation develops a proposed method of support to the process of decision making used in the selection of logistics investment projects, in a large company in the oil and gas industry. In most cases, the criteria used for decision making in project selection only considers the financial aspects, without taking into account other ones, which are addressed in this work. Due to the importance of the projects and the amount of variables involved when selecting and prioritizing them, this work uses the Simplified AHP (Analytic Hierarchy Process) and concepts of Mixed Integer Linear Programming (MILP) to determine priority projects and optimize the satisfaction of the decision-making group. Six of the main projects of the enterprise were studied, which together sum up to approximately 2.7 billion dollars and represent almost 80 per cent of the logistics portfolio of the studied company. This study allowed a more effective selection, resulting in a greater integration between decision makers and a greater knowledge of each of the evaluated projects.

Noise currently represents a problem in society, which disturbs mainly inhabitants in populated areas. It decreases their quality of life and endangers their health. The sensitivity to noise is individual, yet it is possible to measure noise by various means and evaluate its intensity and impact on human beings. Noise as a part of the environment, is becoming on the basis of resident complaints a discussed matter on the town and city level. Their management of noise necessarily involves monitoring and taking subsequent precautions. This work deals with comparing objective and subjective methods in noise evaluation in urban environments and its impact on the quality of life and the health of the residents. It uses a method of the multicriterial evaluation of variant also known as the multicriterial analysis. It compares four approaches to evaluate noise; two objective involving measuring, one subjective using a survey method and one hybrid. The winning method represents the subjective evaluation, which has fulfilled given criteria and acquired a significance of 75 %. All variants included in the analysis are suitable for noise evaluation in outdoor environments on a local level. The outcome of this work is to recommend towns and cities in the Czech Republic to use the winning compromising variant,...
