Design Optimization

Definition

Design optimization is the process of improving a system or component's performance and efficiency by systematically evaluating and refining its design parameters. This approach is essential in engineering to maximize output while minimizing resource use, costs, and environmental impact. In the context of thermodynamic analysis, design optimization involves enhancing the efficiency of energy conversion processes to achieve better performance in systems like concentrated solar power.
