13. BIFUEL CONVERSION OF THERMAL POWER PLANTS UNDER UNCERTAINTY: A REAL OPTIONS APPROACH / CONVERSÃO DE TERMELÉTRICAS PARA BI-COMBUSTÍVEL EM AMBIENTE DE INCERTEZA: UMA ABORDAGEM POR OPÇÕES REAIS
In Brazil, despite the predominant participation of hydro power plants, some years ago, due to Thermo Power Priority Program (PPT), a large number of Natural Gaspowered plants were implanted. A lot of uncertainties are imposed to the players in the Brazilian Power Market, and one more risk arises: the Natural Gas offer. The bi-fuel conversion arises as an op

14. Metodologia de planejamento estratégico de lavra incorporando riscos e incertezas para a obtenção de resultados operacionais. / Strategical minnig planning methodology incorporating risks and uncertanties to obtain operational results.
Strategic mine planning corresponds to the process to determine the best mine design and scheduling according to a previously stablished strategy. It is considered as a key element for the success of a mining venture, once supports the decision process related to it conduct and development. Conventional strategic mine planning methods are based on determinis

16. Uso de poços inteligentes em desenvolvimento de campos de petroleo sob incertezas / Use of smart wells in petroleum field developments under uncertainties
The selection of a production strategy is one of the most important tasks to ensure success of petroleum fields development. In order to improve the performance of fields, the use of smart wells is becoming a common practice. In such wells, devices like valves and sensors are able to monitor and control the production in real time, adding flexibility to the

17. A análise custo-efetividade : sua aplicação como auxílio para a definição de políticas de regulamentação do uso de agrotóxicos
The cost-effectiveness analysis is an analysis that compares the costs and outcomes of two or more projects, and selects the one that gives the best result to improve the well-being of the population. In this dissertation the cost-effectiveness analysis was carried out to analyse four projects that aim to regulate pesticide spray in tomato crops: pesticide m

18. Diretrizes para implantação de sistemas de reúso de água em condomínios residenciais baseadas no método APPCC - análise de perigos e pontos críticos de controle: estudo de caso Residencial Valville I. / Guidelines for water reuse system in residential condominiums based on HACCP method: Valville I case study.
Water is about to become a scarce resource, due to the population growth that increases the demand or even because of the offer reduction, especially due to water springs´ pollution. One of the alternatives to face this problem is the Water Reuse technique, an important instrument to water management and owner of high technologies to its properly utilizatio

20. Comparação de tecnicas de analise de risco aplicadas ao desenvolvimento de campos de petroleo / Comparison of tecniques for risk analysis applied to petroleum field development
Petroleum field decision-making process is associated to high risks due to geological, economic and technological uncertainties, and high investments, mainly in the appraisal and development phases of petroleum fields where it is necessary to model the recovery process with higher precision increasing the computational time. One way to speedup the process is

21. Risk assessment for reservoir development under uncertainty
Decision analysis applied to petroleum field development is always strongly related to risk due to the uncertainties present in the process. Methodologies to quantify the impact of uncertainties are still not well established due to the amount of variables that have to be considered. The complete analysis usually depends on geological, economical and technol

23. Quantificação do impacto de incertezas e analise de risco no desenvolvimento de campos de petroleo
Decision analysis applied to the development phase of petroleum field must take into account the risk associated to several types of uncertainties. In the transition of the appraisal to the development phase, the importance ofrisk associated to the recovery factor may increase significantly. The process is complex due to (I) high investments (2) large number

24. APPLICATION OF FUZZY LOGIC TO THE MUHLBAUER MODEL FOR PIPELINE RISK ANALYSIS / APLICAÇÃO DA LÓGICA NEBULOSA AO MODELO MUHLBAUER PARA ANÁLISE DE RISCO EM DUTOS
W. Kent Muhlbauer made a detailed identification of approximately 300 different conditions that influence in the evaluation of the Risk in a pipeline, so, He proposed a punctuation system that is known as the method of Muhlbauer. Muhlbauer`s method evaluates the several variables that influence in the pipeline Risk by the attribution of quantitative values.
