Tools for Multi-Objective and Multi-Disciplinary Optimization in Naval Ship Design
… or function is an essential prerequisite for optimization and design trade-off. This effectiveness can be limited to individual ship missions or extend to missions within a task group or larger context. A method is presented that uses the Analytic Hierarchy Process combined with …

Experimental and Computational Study of Vibration-Based Energy Harvesting Systems for Self-Powered Devices
… second part of this dissertation, we address the optimization of the output power of piezoelectric energy harvesters of aeroelastic vibrations. Given the complexity of high-fidelity simulations of the coupling between the fluid flow, structural response and piezoelectric transduction, we develop …

On Aerothermal Optimization of Low-Pressure Steam Turbine Exhaust System
… addresses two challenges in the aerothermal optimization of Low-Pressure Steam Turbine Exhaust System (LPES). The first one is the high computational cost due to the complexity of LPES geometry. To make things worse, designers have to consider extra cost caused by change of constraints, …

Multi-Objective Design Optimization Considering Uncertainty in a Multi-Disciplinary Ship Synthesis Model
Multi-disciplinary ship synthesis models and multi-objective optimization techniques are increasingly being used in ship design. Multi-disciplinary models allow designers to break away from the traditional design spiral approach and focus on searching the design space for the best overall design …

Integrated Framework for Aircraft Design and Assembly Tradeoffs
Aircraft passenger traffic is expected to increase and lead to demand for 40,000 new aircraft by 2040. Aircraft production rates have been rising to meet this demand, but delivery backlogs are growing at even faster rates. Large backlogs can lead to missed deliveries, canceled orders, and traffic …

Parametric Optimization Design System for a Fluid Domain Assembly
… with computational fluid dynamics (CFD) and optimization of a 3D jet turbine engine has never been accomplished. This is due mainly to the computational power required, and the lack of associative parametric modeling tools and techniques necessary to adjust and optimize the design. As an …
