IG.810 What Is Design Optimization? Selecting the"best"design within the available means 1. What is our criterion for best"design? objective function 2 What are the available means? Constraints (design requirements) 3. How do we describe different designs? Design Variables 16.810(16682) Massachusetts Institute of Technology
