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.



optiSLang offers efficient methods for solving your tasks in the CAE-field.

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 accessable for parametric sensitivity analysis, optimization or stochastic analysis.
