Three approaches to robust design are described: 1)Robust optimization, i.e., specifying an objective function f and then minimizing a smoothed (robust) version of f by the methods of numerical optimization. 2) Taguchi's method of specifying the objective function as a certain signal-to-noise ratio, to be optimized by designing, performing, and analyzing a single massive element. 3) Specifying an expected loss function f and then minimizing a cheap-to-compute surrogate objective function f, to be obtained by designing and performing a single massive element.10 ppengTechnical reportTR96-31
