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. Linear Programming in the economic estimate of livestock-crop integration: application to a Brazilian dairy farm
ABSTRACT A linear programming mathematical model was applied to a representative dairy farm located in Brazil. The results showed that optimization models are relevant tools to assist in the planning and management of agricultural production, as well as to assist in estimating potential gains from the use of integrated systems. Diversification was a necessar

3. Pão de forma sem glúten a base de farinha de arroz / Gluten free pan bread based on rice flour
It is being a challenge for researchers in the food field to make available to the celiac the variety of foods that they are not allowed to consume. The bread has been studied as deep in it, especially the replacement of the technological functionality of gluten, which is particularly nontrivial. The objective of this work was to develop gluten-free bread ba

4. Método para estimar o tamponamento nutricional para vacas de corte em sistemas pastoris.
Planning forage needs in beef cattle enterprises is necessary for efficient utilization of genetic and environmental resources in pastoral systems and to generate economic benefits in an environmentally sound way. Production risk evaluation is essential in feed planning for cow-calf operations in pastoral systems. The proposed method to accomplish with produ

5. 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

6. 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

7. 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

8. Crop rotation Scheduling - modeling and solution methodolies / Programação de rotação de culturas - modelos e métodos de solução
Over the last decades, various proposals for techniques and processes to increase agricultural sustainability have been put forward. These proposals bring new planning models in which technical and ecological production aspects must be considered, as well as the access of small farmers to the consumer market. In this type of agricultural production planning,

9. Proposta de um modelo de planejamento agregado da produção numa usina de açúcar e álcool vinculado à flutuação de preços em mercados à vista e no mercado futuro. / A model of aggregate production planning in a sugar mill and alcohol linked the decisions of prices in future markets and present markets.
The objective of study this dissertation is to develop a model of aggregate production planning to support the decisions of management and board level of sugar and alcohol plants in regard to varieties of cane harvested each week, purchasing cane of nonsugar, the type of transport (own or outsourced) to use each week, the total cane processed per week for ta
