  • Optimization of laser micro milling of alumina ceramic using radial basis functions and MOGA II

    This paper considers the analysis and optimization of laser micro milling of alumina ceramics using smooth spline analysis of variance (ANOVA), radial basis functions (RBF), and a multi-objective genetic algorithm (MOGA-II). The workflow for the optimization study is developed using the software modeFRONTIER.

  • Optimum Design of Exhaust System of a Ship

    A methodology for the optimization of a silencer in a ship's exhaust system is developed. The study aims to optimize the acoustics and back pressure, with results derived by using the optimization platform modeFRONTIER. The objectives of noise and pressure reduction were both successfully realized in this study, resulting in an optimized and validated system.

  • Performance indices and evaluation of algorithms in building energy efficient design optimization

    Algorithms play a critical role in the effectiveness and efficiency of building energy efficient design optimizations. Stability, robustness, coverage, speed, validity, and locality indices are proposed in this study, to comprehensively evaluate the performance of optimization algorithms. Three commonly used optimization algorithms, namely HookeeJeeves, MOGA-II, and MOPSO, are selected for evaluation.

  • Hybrid flow management - multi objective optimisation

    The objectives of the optimisation management that considers both assembly and production Hybrid Flow-Shops lines are several: optimal numbers of machines, shifts, product priority and time-period scheduling. The approach uses a combination of DES software with an MDO (Multidisciplinary Design Optimization) software, modeFRONTIER. model is optimized following the process: 1) A Multi-objective Genetic Algorithm cycle generates a set of optimal solutions; 2) A Clustering cycle groups the solutions into different sets; 3) The selection of the preferred solution via post-processing; 4) A mono-objective optimisation of each cluster; and 5) creation of weekly scheduling with optimal results.

  • Design and analysis of a new generation of CLT propellers

    The researchers of University of Genoa, in collaboration with SISTEMAR SA, proposed a study to design and analyze a tip loaded propellers to improve full-scale propeller efficiency (lower fuel consumptions and lower emission levels to comply with environmental pollution regulations). The modified tip loaded propeller (a mix between a tip rake and a contracted and tip loaded propeller) is designed via an optimization strategy using a Boundary Elements Method (BEM), a custom parametric description of the unconventional blade geometry and an optimization algorithm within the modeFRONTIER environment.

  • Sensitivity analysis of urban morphology factors regarding solar energy potential of buildings in a Brazilian tropical context

    Planning the urban morphology of the built environment is a key issue in shifting to a climate adapted urban environment. This paper addresses an important threefold energy challenge of tropical cities: the major potential of harnessing solar energy as renewable resource for local electricity production and the energy-saving paradox of reducing the undesirable solar heat gains in buildings while providing satisfactory levels of daylight. It aims at measuring the effect size of urban form factors regarding these energy goals.
