2. An overview of flexibility and generalized uncertainty in optimization
Two new powerful mathematical languages, fuzzy set theory and possibility theory, have led to two optimization types that explicitly incorporate data whose values are not real-valued nor probabilistic: 1) flexible optimization and 2) optimization under generalized uncertainty. Our aim is to make clear what these two types are, make distinctions, and show how

3. OS CUSTOS DE TRANSAÇÃO DA CADEIA PRODUTIVA DO BIODIESEL À BASE DE SOJA NO RIO GRANDE DO SUL: IMPACTOS SOBRE A GESTÃO DAS CADEIAS DE SUPRIMENTOS DAS USINAS INSTALADAS / THE TRANSACTION COSTS OF THE PRODUCTIVE CHAIN OF THE BIODIESEL BASED ON SOYBEAN IN RIO GRANDE DO SUL: IMPACTS ON THE MANAGEMENT OF SUPPLY CHAINS OF PLANTS INSTALLED
This research aims to identify and assess the main sources of transaction costs of the productive chain of soy biodiesel in Rio Grande do Sul and how they affect the management of supply chains of organizations. To do so, proceeded with semi-structured interviews and visits to four plants in operation in Rio Grande do Sul state. It is diagnosed that the main

4. AVALIAÇÃO DE INVESTIMENTOS SOB INCERTEZA: UM ENFOQUE CRÍTICO / INVESTMENT ANALYSIS UNDER UNCERTAINTY: AN ANALYTICAL APPROACH
The valuation of investment opportunities is undoubtedly a topic of great interest as it is the manner by which firms guide their investment decisions and assess whether this or that project creates or not value. The valuation theory of productive investments starts its way on the Net Present Value Rule (NPV) and branches along its literature, pursuing alway

5. JustificaÃÃo de investimentos em tecnologias avanÃadas de manufatura: um framework para a avaliaÃÃo da opÃÃo de esperar, sob a Ãtica das opÃÃes reais
Evaluating capital investment projects for the adoption of advanced manufacturing technologies (AMT) is a critical task faced by manufacturing managers. Due to the normally high levels of risk and uncertainty involved, the traditional investment appraisal techniques are often insufficient and must be complemented by sophisticated evaluation methods. Since th

7. Retroanálise probabilista aplicada à análise dinâmica da cravação de estacas. / Probabilistic back-analysis applied to dynamic loading test for pile driving.
An dynamic loading test can be performed in concrete piles, bored piles, drilled shafts, auger cast-in-place (continuous flight auger) piles. Such essay bases on the Theory of the Propagation of Wave in piles with the aim of evaluate the capacity of static load mobilized from the dynamic event. The analysis of the test is made by a PC program (p.e. CAPWAP or

9. Bayesian inference in the assessment of precast piles foundations safety. / Inferência bayesiana na avaliação da segurança de fundações em estacas de deslocamento.
The theme of "foundations safety" deserves special attention in theory and practice, due to the need to find optimized solutions, which balance cost and safety, solutions that differ in their method of uncertainty treatment. An important way of coping with these uncertainties is the proof pile load tests. Recently, the importance of proof load tests in the r

10. Estimação de posição e quantificação de erro utilizando geometria epipolar entre imagens. / Position estimation and error quantification using epipolar geometry between images.
Position estimation is the direct result of scene reconstruction, one of computer visions fields. It is also an important information for the control of mechanical systems - specially the autonomous robotic systems. As an engineering application, those systemsperformance must be evaluated in terms of efficiency and effectiveness, measured by processing costs

12. VALUATION OF AN OPTION OVER A FUTURE CONTRACT / VALORAÇÃO DE UMA OPÇÃO SOBRE UM CONTRATO FUTURO
The object of this work is to develop a model based on techniques of simulation and binomial tree to valuate a call option over a future contract. The tool will be based on the theory of derivatives and stochastic processes to simulate the behavior of the active object. The model Black, Derman &Toy uses binomial tree to construct future possibilities of exer
