8. A NEW MATHEMATICAL MODEL FOR THE WORKOVER RIG SCHEDULING PROBLEM
ABSTRACT One of the most important activities in the oil and gas industry is the intervention in wellsfor maintenance services, which is necessary to ensure the constant production of oil. These interventions are carried out by workover rigs. Thus, the Workover Rig Scheduling Problem (WRSP) consists of finding the best schedule to service the wells while con

9. Solving the Integrated Schedule Generation and Fleet Assignment Problem: an ACOBased Metaheuristic Approach
Abstract Traditionally, the initial steps on airline planning – Schedule Generation and Fleet Assignment problems – are solved separately. This traditional approach usually leads to suboptimal solutions, since flight profitability – the decision criteria to schedule a flight – depends on what aircraft type will be used on that flight. On the other ha

11. 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
