1. Classical and stochastic mine planning techniques, state of the art and trends
Abstract Determination of the best possible ultimate pit for an open pit mine is a fundamental subject that has undergone a highly evolutionary process, reviewed in this study, since the correct choice carries substantial economic impact for the industry. The correct choice can be very beneficial for project analysis, whereas an incorrect choice has the pote

2. Modeling Bayesian Networks from a conceptual framework for occupational risk analysis
Abstract Occupational risk is the possibility that some element included in a particular work environment can cause damage to someone’s health. Thereby, the risk is understood as the product of probability and consequences. In this sense, risk analysis through probabilistic stochastic techniques, such as Bayesian networks (BN), becomes an important tool to

3. INCLUDING RISK IN ECONOMIC FEASIBILITY ANALYSIS:A STOCHASTIC SIMULATION MODEL FOR BLUEBERRY INVESTMENT DECISIONS IN CHILE
ABSTRACT The traditional method of net present value (NPV) to analyze the economic profitability of an investment (based on a deterministic approach) does not adequately represent the implicit risk associated with different but correlated input variables. Using a stochastic simulation approach for evaluating the profitability of blueberry (Vaccinium corymbo

4. Application of Bayesian Networks in the human error contribution analysis of collision accidents. / Aplicação de Redes Bayesianas na análise da contribuição do erro humano em acidentes de colisão.
Recently, in the naval industry, the normalization of classification societies and IMO (International Maritime Organization) has presented a gradual change, going from prescriptive procedures to a regulatory structure based on risk. That perspective offers some advantages to operators and constructors: 1) greater capacity to incorporate innovations in design

5. Gestão do valor nas empresas num contexto de risco: estudo de caso de uma empresa do setor não cíclico de alimentos da BOVESPA / Value managment of companies in a risk view: a case study of Bovespa`s aciclic food company
Since the 90th decade, the brazilian economy has passed through many industry privatization. This process has changed in different ways the trends of brazilian economy view, bringing the attention of many investors that dealt a lot with the fusion and acquisition market. In this view the acyclic stock exchange of São Paulo(BOVESPA) is presenting in the last

6. Methodology of production strategy optimization based on genetic algorithms / Metodologia de otimização probabilistica de estrategias de produção baseada em algoritmos geneticos
High levels of uncertainty and associated risks in the exploration and production of some oil fields suggest the use of probabilistic optimized production strategies. Therefore, an appropriate production strategy should be chosen considering various geological and economic scenarios. In this work, a new approach for the optimization is proposed where the pro

8. Investment analysis of a thermal power plant: a deterministic and probabilistic assessment / AnÃlise de investimento de uma usina termelÃtrica : uma abordagem determinÃstica e probabiÃstica
Concerning the main changes which took place in the Brazilian electrical sector, there was an increase of competitiveness, especially in the field of energy production, where the new policy of buying and selling electricity occurs by means of auctions. This thesis has as an objective to demonstrate through deterministic and probabilistic studies the better l
