1. Analysis of the impacts of slope angle variation on slope stability and NPV via two different final pit definition techniques
Abstract The traditionally and widely used Lerchs-Grossmann algorithm presents well-known limitations that newer propositions attempt to overcome. The direct block schedule (DBS) methodology, which has gained relevance with computational advances, obtains the final pit as a natural result of production sequencing, different from Lerchs-Grossmann-based algori

2. Construction duration predictive model based on factorial analysis and fuzzy logic
Resumo A definição do prazo de execução de obras residenciais verticais ocorre ainda na fase de estudo de viabilidade econômica e financeira do empreendimento e, na maioria das vezes, de forma empírica, aumentando as incertezas e os riscos para o cumprimento do prazo estabelecido. No entanto, existem ferramentas de inteligência computacional que podem

4. Boom, Burst, and Doom: The Petrochemical Complex of Rio de Janeiro as Catalyzer of Urban-Regional Development
Resumo O desenvolvimento liderado por recursos naturais é amplamente debatido por conta das dificuldades de se converter a riqueza mineral em maior bem-estar social. Assim, a construção do Complexo Petroquímico do Rio de Janeiro - COMPERJ no estado do Rio de Janeiro, o maior produtor brasileiro de petróleo e gás, foi empreendida como uma estratégia de

5. Application of ISO 31000 standard on tailings dam safety
Abstract Tailings dam safety is a frequent subject of discussion during mining project development. However, due to recent accidents with these structures, this issue has become even more prominent. A highlighted point is the risk management, which can be defined as the identification, analysis and maintenance of risks at acceptable levels during the design,

6. Evaluation of an iron ore price forecast using a geometric Brownian motion model
Abstract Mining projects are often budgeted in millions of dollars, making it of interest to the investor to measure a project’s uncertainties and risks, which include the changes in the commodity price. The simulation of asset prices is valid because it enables displaying, with a degree of certainty, the future behavior of a financial asset. One of the mo

7. Analysis of the Insertion of Particular Photovoltaic Generation in the Low Voltage Installations, Under the Approach to Performance, Safety, Maintenance and Operation of the PVS
ABSTRACT The growing use of Photovoltaic Solar Energy in Brazil, both in power plants and in distributed generation systems, brings with it a series of practical and technical questions that are not limited to the design and project of the systems. Environmental factors and resources related to the use, operation, maintenance, decommissioning and final dispo

8. 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

9. Detection of schistosomiasis in an area directly affected by the São Francisco River large-scale water transposition project in the Northeast of Brazil
Abstract INTRODUCTION: The development of the São Francisco River Integration Project [Projeto de Integração do Rio São Francisco (PISF)] in the State of Ceará, Brazil, has resulted in environmental and socioeconomic changes with potential risks to public health. We aimed to determine the presence of Schistosoma mansoni infections in schoolchildren (a

10. 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

11. Economic valuation of a toll road concession with traffic guarantees and the abandonment option
Abstract Governments worldwide have been encouraging private participation in transportation infrastructure. To increase the feasibility of a project, public-private partnership (PPP) may include guarantees or other support to reduce the risks for private investors. It is necessary to value these opportunities under a real options framework and thereby analy

12. PROJECT SCHEDULING OPTIMIZATION IN ELECTRICAL POWER UTILITIES
The problem of choosing from a set of projects which ones should be executed and whenthey should start, depending on several restrictions involving project costs, risks, limited resources, dependencies among projects, and aiming at different, even conflicting, goals is known as the project portfolio selection (PPS) problem. We study a particular version of t
