The aim of almost all design tasks in engineering is to determine a robust design. In order to assess the robustness, the uncertainty of input parameters has to be taken into account. The incorporation of uncertain parameters in an optimization task may succeed in an active or passive manner. In this contribution, the theoretical bases of active and of passive optimization strategies are introduced...
In many engineering applications, a structural design is determined by way of a multi‐stage design process. Thereby, the information of previous simulations, e.g. sensitivity analysis, should be used for further investigations. In special, the aim is to improve the reliability as early as possible. Therefore, an approach is presented to determine alternative permissible design spaces on the basis...
In engineering practice, the assessment of sensitivity is utilized to detect influential parameters in order to facilitate subsequent numerical simulation techniques. As sensitivity analyses are preprocessing methods for sophisticated numerical simulation techniques, e.g. reliability based optimization procedures, their application is always linked to an increase of the computational expense. In result,...
