1. Statistics of the Pareto front in Multi-objective Optimization under Uncertainties
Abstract In this paper we address an innovative approach to determine the mean and a confidence interval for a set of objects analogous to curves and surfaces. The approach is based on the determination of the most representative member of the family by minimizing a Hausdorff distance. This method is applied to the analysis of uncertain Pareto frontiers in m

2. Multi-objective optimization with Kriging surrogates using “moko”, an open source package
Abstract Many modern real-world designs rely on the optimization of multiple competing goals. For example, most components designed for the aerospace industry must meet some conflicting expectations. In such applications, low weight, low cost, high reliability, and easy manufacturability are desirable. In some cases, bounds for these requirements are not cle

3. Structure Comparison and Optimal Design of 6-RUS Parallel Manipulator Based on Kinematic and Dynamic Performances
Abstract The effects of distinctive parameters such as revolute joint angle or spherical joint location of mobile platform in a 6-DOF 6-RUS parallel manipulators on workspace, kinematic, and dynamic indices are investigated in this study to select proper structure commensurate with performance. Intelligent multi-objective optimization method is used to desig

4. Design Optimization of a Random Suspension Device Considering a Reliability Constraint on the Frequency Response Function
Abstract This work deals with the design of a suspension device, idealized as a spring-mass-damper system. The amplitude of a nominal system is constrained to satisfy certain limitations in a given frequency band and the design is to be done as a reliability-based optimization. This constitutes a major difficulty since the constraint becomes a random process

5. Optimización de los Parámetros de Soldadura por Arco Sumergido en Acero HSLA: una Aplicación para Manufactura de Tuberías de Conducción de Hidrocarburos
Abstract The HSLA steel API 5L X70 is used to manufacture pipes for transporting hydrocarbons. The construction of pipe of this material involves high amount of welding, where the parameters used affect directly in the metallurgical structure and in the mechanical properties thereof when welded. Thus, to study the impact of the parameters of the submerged ar

6. Sistema imunologico artificial para otimização multiobjetivo / Artificial immune system for multiobjetive optimization
The aim of this work is to explore an Artificial Immune System, based on the Clonal Selection principle, in the solution of Multiobjective Optimization problems. Artificial Immune Systems have, in their elementary structure, the main characteristics required to solve Multiobjective Optimization problems: exploration, exploitation, paralelism, elitism, memory

7. Evolutionary multi-objective algorithms for Phylogenetic Inference / Algoritmos evolutivos multi-objetivo para a reconstrução de árvores filogenéticas
The phylogeny reconstruction problem consists of determining the evolutionary relationships (usually represented as a tree) among species. This is a very complex problem since the tree search space is huge. Several phylogenetic reconstruction methods have been proposed. Many of them defines an optimality criterion for evaluation of possible solutions. Howeve

8. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

9. Multi-objective approach to protein tertiary structure prediction / Algoritmo híbrido multi-objetivo para predição de estrutura terciária de proteínas
Muitos problemas de otimização multi-objetivo utilizam os algoritmos evolutivos para encontrar as melhores soluções. Muitos desses algoritmos empregam as fronteiras de Pareto como estratégia para obter tais soluções. Entretando, conforme relatado na literatura, há a limitação da fronteira para problemas com até três objetivos, podendo tornar seu
