1. A GENERIC TACTICAL PLANNING MODEL TO SUPPLY A BIOREFINERY WITH BIOMASS
ABSTRACT The supply chains which bring biomass to biorefineries play a critical role in biofuel production. Optimization models can help decision makers to design more efficient chains and minimize the cost of biomass delivered to the refineries. This article based on a French national research project on biomass logistics considers one refinery, able to pro

2. Decision support bioeconomic model for livestock systems / Modelo bioeconômico para suporte à decisão em sistemas pecuários
Rural managers make decisions in uncertain and dynamic environments. These characteristics, associated with bounded rationality can lead to the formulation of mental models that reflect reality in a distorted way. In this context, the procedures for modeling and simulation are important tools to understand how the production systems operate and to make decis

4. A quantitative and qualitative approach for targeting as a weapon-target assignment.
This essay presents the construction of a two-steps approach using Weapon-Targeting Assignment (WTA) problem mathematical modeling and Analytical Hierarchy Process (AHP) addressing two phases of the the targeting cycle, concerning both targeting and weaponeering activities on the context of a small Joint Force Air Component, in order to support timely, feasi

5. Análise matemática de um modelo de controle de populações de mosquitos / A mathematical analysis of a model for control of mosquito populations
The proliferation of mosquitoes in inhabited regions is an important public health issue since these insects are vectors of several infectious diseases. Thus, the study of techniques for controlling of mosquito populations has an important role in the quest for efficient combat techniques; in particular, the adequate understanding of mathematical models that

6. Métodos e processos para a análise experimental de sistemas oceânicos de produção de petróleo e gás. / Methods and procedures for the experimental analysis of offshore systems for oil and gas production.
The increasing complexity of o shore system operations for oil and gas production is a reality. Currently, the need to evaluate the seakeeping of these systems requires understanding some phenomena not yet explored and, for that reason, researches using experiments with small scale models become indispensable. Results obtained in model basins require methodo

8. Fuzzy modeling to predict the risk of recurrence and progression of superficial bladder tumors / Modelagem fuzzy para predizer os riscos de recidiva e progressão de tumores superficiais de bexiga
Nowadays, the bladder cancer is the fourth most common cancer in adults and the second most frequent urogenital tumor. Predicting recurrence and progression of superficial bladder tumors, with available clinical information to decide the therapy to be used is hard work. In this work, two mathematical models were developed to help specialist on the decision p

9. Modelagem do planejamento agregado da produção em usinas cooperadas do setor sucroenergético utilizando programação matemática e otimização robusta
The main concern of this work is related to the development of an aggregate production planning model of a cooperative society of sugar and alcohol milling companies. This mathematical model is based on a hierarquical approach between the annual planning problem of the cooperative and the tactical planning horizon of the sugarcane mills. In the cooperative l

10. Otimização no planejamento agregado de produção em indústrias de processamento de suco concentrado congelado de laranja
This work aim at developing models using linear programming, goal programming and robust optimization to support decision making in the frozen concentrated orange juice planning process. The proposed model includes orange harvesting plan, which takes into account oranges maturation curves. This fact leads to a model that incorporates a large portion of the s

11. Expoente de Hurst e diagrama de fase para persistência induzida amnesticamente em processos não-markovianos. / Hurst exponent and the phase diagram for persistence induced amnestic on a non-Markovian
Nowadays there has been a growing interest in anomalous diffusion: the super difusive and sub-difusive processes. The problem about normal diffusion already well established whereas many problems still exist in anomalous diffusion. Several mathematical models and computational techniques have been developed to model such processes. In this work we studied a

12. ProgramaÃÃo linear inteira aplicada no planejamento da alocaÃÃo de vagÃes de carga / Integer linear programming applyed for railroad freight wagons allocation planning
Load transportation attendance for demand is related to the process of wagon allocation that in its turn, is associated with the way by which the decision is taken. The distribution of the wagons to the shipment terminals depends on the planning and movement of the empty wagons, being the trip of the empty wagon the parcel with bigger financial impact on the
