13. Planejamento do "mix energÃtico" de geraÃÃo de energia elÃtrica no Brasil : uma avaliaÃÃo da aplicabilidade de otimizaÃÃo linear multiobjetivo no contexto do novo modelo institucional do setor elÃtrico
This dissertation was developed having as premisse to be including and to allow easy understanding of the displayed, preventing, however, the superficiality. It composes of three independent parts that complete themselves, in the case, the chapters 2, 3 and 4, which can be read in the order where to desire, after the introduction of Chapter 1. Each part woul

14. A contribution to the study about multicriterion optimization methods / Uma contribuição ao estudo dos métodos de otimização multi-objetivo
In optimization problems, there are many situations in which the users goal is to minimize and or maximize several functions simultaneously, instead of dealing with a single objective function. These functions form a mathematical description of performance criteria, which are usually in conflict with each other. This situation is formulated as a multicriteri

15. Rehabilitation analysis of the water distribution networks by multiobjective genetic algorithms / Análise de reabilitação de redes de distribuição de água para abastecimento via algoritmos genéticos multiobjetivo
Recognizing the importance of water as a limited natural resource and considering the prospect of continued population growth, it is important to investigate water distribution systems which are common to all urban infrastructures. Planning of the water distribution network rehabilitation becomes additionally important given economic constraints and operatio

16. Otimização multiobjetivo para a operação de sistemas urbanos de abastecimento de agua
The proper operation of the urban water supply systems has a direct impact on the water to be provided to the quality consumers. The optimization of these systems appears as an alternative to search efficient and also efficient solutions, thus guaranteeing the management of the systems. Many research works have been reported in the literature describing appl

17. Alocação computacional inteligente de autoestruturas para controle multivariavel
In this thesis a proposal for eigenstructure placement for multivariable linear dynamic systems by state feedback based on the linear quadratic regulator (LQR), multiobjective optimization, evolutionary computation and parallel programming is presented. The eigenstructure placement problem is formulated based on LQR designs and on an inequality method to con

18. Otimização da operação de fornos eletricos de arco direto
An optimisation model for the operation of direct arc electric furnaces that use scrap as the main raw material is presented in this thesis. A knowledge of the electric circuit to which the furnace is connected, as well as the design and operational characteristics of the equipment, are required for the modelling. A backward dynamic programming routine is em

19. Funcionalidades basicas para um sistema interativo de sequenciamento em plantas multiproposito
This thesis presents the development of a scheduling interactive for multipurpose batch plants. Real scheduling problems have multiobjective characteristics. In this work the interactive system uses a single objective cost unction and leaves the user responsible for obtaining a good compromise between comfliting objectives.The model used in the optimization

21. Planejamento da expansão da geração de sistemas hidrotermicos de potencia, otimizando os usos multiplos da agua dos reservatorios
A substantial contribution to the development of generation expansion planninq for hydrothermal power systems is aimed at in this work. The possible multiple uses of the water from candidate hydro plant reservoirs are considered, employinq conversational techniques of multiobjective programminq. Initially, a modeling based on linear programming is presented
