Scope
The performance evaluation and design of complex engineering systems, such as ships and offshore structures, require multidisciplinary analysis and optimization methods. The use of interconnected discipline solvers must be managed during the analysis and design optimization process and a trade-off among several multidisciplinary objectives must be carefully considered. The design of innovative products operating in real-life conditions requires the application of high-fidelity solvers along with global optimization procedures and uncertainty quantification methods for uncertain operating/environmental conditions. To make the multidisciplinary analysis and optimization process accurate and at the same time affordable, advanced multidisciplinary architectures and methodologies must be developed and assessed. |
