Robust Design Optimization (RDO) in virtual product development

What would be your benefit if you knew to what extent your product development comes close to a reliable economic optimum? How robust is your design in reality?

Conducting a sensitivity analysis, multidisciplinary optimization, robustness evaluation and reliability analysis with optiSLang enables you to:

  • Quantify risks
  • Identify optimization potential
  • Improve product performance
  • Secure resource-efficiency
  • Save time to market

optiSLang automatically identifies the relevant input and output parameters and quantifies the forecast quality with the help of  the Coefficient of Prognosis ( CoP) and the Metamodel of Optimal Prognosis (MOP). A predictable prognosis quality is the key to an efficient optimization. Thus, a "no run too much" philosophy can be implemented to minimize solver calls. As a consequence, even optimization tasks involving a large number of variables, scattering parameter as well as non-linear system behavior can be solved. optiSLang’s Best-Practice-Management automatically selects the appropriate algorithms, such as gradient methods, genetic algorithms, evolutionary strategies or Adaptive Response Surface Methods. Furthermore, all methods of optimization and stochastic analysis can be combined in regard to the particular task. optiSLang makes you ready to meet the full range of parametric studies to innovate and accelerate your virtual product development.

Process Integration

Simulation processes from different solvers (ANSYS, MATLAB, Excel, Python ...) or pre and post processors can be adapted via a graphic editors and ASCII files making them accessible for parametric sensitivity analysis, optimization or stochastic analysis.

General Features
