Design optimization
open-in-new
<p>Design optimization is an engineering design methodology using a mathematical formulation of a design problem to support selection of the optimal design among many alternatives. Design optimization involves the following stages: </p> <ol><li><a href="/facts/Variable_(mathematics)/VbQlrvKz">Variables</a>: Describe the design alternatives</li> <li>Objective: Elected functional combination of variables (to be maximized or minimized)</li> <li>Constraints: Combination of Variables expressed as equalities or inequalities that must be satisfied for any acceptable design alternative</li> <li>Feasibility: Values for set of variables that satisfies all constraints and minimizes/maximizes Objective.</li></ol>
