Robust Design Optimization (RDO) in virtual product development

Robust Design Optimization often means to explore the limits of product performance, which might be associated with risks. 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?

Because of the need to further optimize product performance and resource consumption while reducing development time, RDO using CAE-based multi-objective and multi-disciplinary optimization and stochastic analysis is becoming more and more a key component in virtual product development. In order to consider a large amount of multi-disciplinary, non-linear optimization variables with different priorities, an efficient and meaningful sensitivity analysis and robustness evaluation is inevitable.

optiSLang identifies automatically 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 forecast quality is the key to an efficient optimization. Thus, a "no run too much" philosophy can be implemented to minimize solver calls. 

optiSLang helps you to quantify risks, to identify optimization potentials and to adjust safety margins without limitation of input parameters. Thus, you can safely meet the requirements under consideration of all potentially effecting uncertainties and tolerances.

Process Integration

Simulation processes from different CAE programs, pre and post processors can be adapted via a graphic editor over ASCII files and can access a parametric sensitivity study, optimization or stochastic analysis.


Here you will find several successful examples of solving various optimization and stochastic problems in the CAE area with optiSLang.

optiSLang inside ANSYS Workbench

With the software version optiSLang inside ANSYS Workbench, the strength of ANSYS Workbench – multidisciplinary, fully parametric, automated CAE computational processes – and the strength of optiSLang – highly efficient, automated workflow of Robust Design Optimization – are interactively combined.

Software on Demand

optiSLang is also available as software on demand in Germany, Austria and Switzerland. This service provides fast and economical access to the latest software version for a customized billing of use. For further information, please contact our support.


optiSLang is sold worldwide. A list of our distributors can be found here.
