Estudo comparativo de modelos matemáticos de qualidade de águas superficiais

Surface water quality models have been developed since 1925, when Streeter e Phelps created first order equations that represent the balance between DO and BOD. Since then, and specially after the ‘60s, new computational technologies evolved, making it possible to create more complex models, which try to represent, through mathematics, natural phenomena like eutrophication and rivers self-depuration. As main objective of such models is the understanding of aquatic systems and the relationship between them and the environment, so that it can support decision makers in creating water manage plans and in elaborating environmental projects of such resources. Regarding to that, it is of crucial importance the understanding of the models structures, so that one can choose the most appropriate model for the river in question. While one-dimensional models like QUAL2K are more appropriate for long and narrow rivers, bi- or tridimensional models (CE-QUAL-W2, WASP and CEQUAL- ICM) are more commonly used in wide and slower rivers, with higher lateral and/or vertical mixes rates. Besides, the more complex is the river studied more complex the model should be, which demands more costs and time for the model to be applied

Um problema de corte de estoque multiobjetivo

In this paper we deal with the one-dimensional integer cutting stock problem, which consists of cutting a set of available objects in stock in order to produce ordered smaller items in such a way as to optimize a given objective function, which in this paper is composed of three different objectives: minimization of the number of objects to be cut (raw material), minimization of the number of different cutting patterns (setup time), minimization of the number of saw cycles (optimization of the saw productivity). For solving this complex problem we adopt a multiobjective approach in which we adapt, for the problem studied, a symbiotic genetic algorithm proposed in the literature. Some theoretical and computational results are presented.
