Problem Description
Robust Parameter Design selects designs insensitive to the variation of given parameters.
This example demonstrates:
Problem descriptionThis is the twobar truss as considered in RBDO example. The problem has two variables: the crosssection area of the bars (Area) and the leg width (Base). The bar thicknesses are noise variables while the leg widths are adjusted (control variables) to minimize the effect of the variation of the bar thicknesses. A value of the Base variable must be obtained that makes the stress response insensitive to variation of the Area variable.

Design Formulation
The design formulation is as follows:
 A value of the base variable must be obtained that makes the stress response insensitive to variation of the area variable.
