Um modelo de fluxo de potência ótimo descontínuo e não suave com restrições de segurança pós-contingências
(Universidade Estadual Paulista (Unesp), 2020-01-29)
Após a formulação do problema de fluxo de potência ótimo por Carpentier em 1962, vários trabalhos têm sido apresentados na literatura, os quais abordam diferentes modelos para o problema de fluxo de potência ótimo. Neste ...
Programação em lógica não-monotônica aplicada à redução do espaço de planos em processos de decisão de Markov
(Centro Universitário FEI, São Bernardo do Campo, 2016)
Um desafio presente em problemas de tomada de decisão sequencial é o fato de que, ao longo do tempo, um domínio pode sofrer alterações não previstas. Enquanto que descrever apenas o domínio atual faz com que a chance de ...
Aplicação de técnicas de otimização à engenharia de confiabilidade
(Universidade Federal de Minas GeraisUFMG, 2008-03-28)
This thesis aims to present Traditional as well as Computational Intelligence Based techniques for reliability modeling and analysis of repairable and non-repairable systems. The more recent applications of Computational ...
On the resource allocation for political campaigns
(Wiley, 2021)
In an election campaign, candidates must decide how to optimally allocate their efforts/resources optimally among the regions of a country. As a result, the outcome of the election will depend on the players' strategies ...
Robust randomized matchings
(Informs, 2018-05)
The following game is played on a weighted graph: Alice selects a matching M and Bob selects a number k. Alice's payoff is the ratio of the weight of the k heaviest edges of M to the maximum weight of a matching of size ...
Risk management for forestry planning under uncertainty in demand and prices
(Elsevier, 2018)
The paper presents and compares approaches for controlling forest companies' risk associated with advance planning under variable future timber prices and demand. Decisions to be made in advance are which stands to cut and ...

INTERACTIVE MULTIOBJECTIVE TABU/SCATTER SEARCH BASED ON REFERENCE POINTBÚSQUEDA TABÚ/DISPERSA MULTIOBJETIVO INTERACTIVAS BASADAS EN PUNTO DE REFERENCIA
(2014-07-01)
This paper presents multiobjective tabu/scatter search architecture with preference information based on reference points for problems of contin- uous nature. Features of this new version are: its interactive behavior, its ...
El balance entre eficiencia y equidad en las intersecciones semaforizadas
(Universidad de los AndesIngeniería CivilFacultad de IngenieríaDepartamento de Ingeniería Civil y Ambiental, 2020)
There are multiple ways to optimize a signalized intersection, the optimization can be done multi-objective, in saturated or unsaturated conditions, and in a single intersection or in several. What we have in common is ...
A Multi-Stage Stochastic Non-Linear Model for Reactive Power Planning Under Contingencies
(Institute of Electrical and Electronics Engineers (IEEE), 2013-05-01)
This paper presents a model for long-term reactive power planning where a deterministic nonlinear model is expanded into a multi-stage stochastic model under load uncertainty and an N-k contingency analysis. Reactive load ...
