1. A review of three decades of research on some combinatorial optimization problems
This paper presents an overview of our research in combinatorial optimization problems. Over the last three decades, our team has been studying mostly optimization problems that arise in industrial environments through the elaboration and solution of mathematical decision models. In addition to elaborating innovative models, we have improved upon existing so

2. Proposta de um modelo em programação linear para a solução de problemas de sistemas produtivos job shop com setup dependentes da sequência / Proposal of a linear programming model for solving problem systems job shop production with setup times sequence-dependent
Sequencing problems are very common, they happen every time there is a choice regarding the order in which several tasks can be performed. The business can be an airline, a hotel, a computer manufacturer or a university; these issues are part of their routine. The application of the sequencing techniques allows, for example, reducing the costs and fastening

3. Análise e proposta de melhoria do processo de previsão de demanda em uma pequena empresa do setor de cosméticos
Nowadays, even small-sized enterprises are investing in integrated management systems, called ERP (Enterprise Resource Planning), as a way to solve planning problems and to better control their cash flow. However, these enterprises end up neglecting one of the main inputs to improve the PPC (Production Planning and Control): the demand forecast. Thus, planni

4. MONITORING FLEXIBLE RISERS WITH OPTICAL FIBER SENSORS / MONITORAMENTO DE RISERS FLEXÍVEIS COM SENSORES A FIBRA ÓPTICA
The interest in structural health monitoring of flexible risers has grown significantly in recent years. For ducts that are already reaching their design life, monitoring systems can provide early warnings of potential failures and also assist the operator in scheduling downtime. Different techniques are being tested by operators of flexible pipes such as au

5. Um modelo de simulação de sistemas aplicado à programação da produção de um frigorífico de peixe
The necessity for making production processes more efficient and effective is the desire of any organization. For this to become reality and does not generate high investment is necessary to use techniques that assist in improvement of the production process along with a appropriate schedule of productive resources. Among these techniques, the Simulation ass

6. Análise da integração de sistemas hierárquicos para planejamento e programação de produção / Analysis of hierarchical system integration for production planning and scheduling
The efficient use of installed capacity in discontinued production plants (flexible, multi-purpose) in such a way as to analyze the feasibility of standard-less demands of different products is a trend in recent years. The main objective of the production problem is to fulfill orders in a relatively short time, in a way that it is client-focused and enables

7. Implantação de sistemas de programação detalhada da produção: levantamento das práticas de programação da produção na indústria. / Implantation of systems of production scheduling: survey of the practical of the production scheduling in the industry.
Due to the great pressure to reduce inventory and delivery, together with the increasing variety of products, production planning and control (PPC) has become increasingly complex and challenging. Basically, this activity aims business planning and control productive resources, to meet customer demand. Traditionally, the literature has addressed the systems

8. Flexible flow line with setup times: heuristic methods / Flexible flow line com tempos de setup: métodos heurísticos
This work addresses the job scheduling on a flexible flow line with separate setup times. According to the literature, this scheduling problem can be considered as a special case of the Flow Shop with multiple machines, where the jobs may skip stages. Two modeled problems have been studied. In the first scheduling problem the setup times are sequence indepen
