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 optimization and testing of high-performance motors
This article has reported on an industrial R&D project aimed at identifying a cost-effective response to the more and more challenging high-speed motor requirements that presently come from the gas industry sector. To meet the very high efficiency, dynamic performance, and reliability standards required by cutting-edge turbomachinery drive applications, a special PM synchronous motor prototype has been developed.
Vehicle steering pull - from product development to manufacturing
The objective of this paper is to propose a novel method to evaluate the impact of dimensional variations on vehicle steering pull. The proposed method combines Monte Carlo simulation to validate the dimensional tolerances, a multibody software to simulate initial data and modeFRONTIER to create a polynomial response surface and simulate the Vehicle Residual Aligning Torque (VRAT) distribution curve, final directional vehicle trend, and factors influence on VRAT.
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.
Situated Design Optimization of Haptic Devices
It is a complex task to develop and optimize a high-performing haptic device, mainly because of the multi-domain and multi-criteria performance requirements for such devices. The general goal for the research presented in this paper is to further develop the previously proposed model-based framework and methodology into a situated and computationally efficient design framework for multiobjective optimization of haptic devices.
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.
