Using the FITradeoff Method for portfolio selection based on the Benefit-to-cost Ratio approach in the context of dengue prevention and control in Brazil

According to data from the World Health Organization, the global incidence of dengue fever has been increasing over the last few decades. Approximately half of the world's population is at risk of contracting the disease. The main form of prevention is the fight against Aedes aegypti mosquitoes. Various actions have been developed over the years to combat dengue fever, but each one has an implementation cost and municipalities have a limited budget. In view of this, this paper presents a real-life application of the FITradeoff Method for portfolio selection using a benefit-to-cost ratio (BCR) approach. The use of the BCR approach is an advantage, as it is an efficient way that requires little computational effort. This method uses partial information provided by the decision-maker which is converted into inequalities and inserted into linear programming models. In this way, it is possible to order the projects and select them according to the available budget.
