The results show a trade-off between accurate representation of problem data and computational performance. Three alternative process models for the energy-intensive melt shop of a steel plant are proposed and linked to a discrete-time formulation. It is claimed that optimization tools of today can effectively support the plant level production. Optimization and Continuous Time Signals.

A new discrete-time aggregate formulation is proposed to rapidly plan the production levels. For instance, usability, interfacing and integration are some aspects discussed in the paper.

Its main objectives are to pursue deep studies in areas of mathematics, to train young researchers at several stages of their career, and to foster and develop applications to relevant problems in the Sciences and from Industry. The increased visibility of this field in the unit is a consequence of the merge of two former units. Research topics of this kind vary from forest management inestigacao analysis and simulations of reaction-diffusion models, the dynamics of fish populations, dengue epidemiology, health care data, sensor location analysis, mass rescue operations, fishing surveys sampling operations, bus driving rerostering, parking enforcement agents routing, and optimal scheduling of petroleum refineries.
