Robust Design

Robust Design

Robust Design is the designing of products, devices and production equipment so that their performance and function is insensitive to the numerous sources of variation such as production and assembly tolerances, ambient use conditions, or degradation over time.


Offering an enormous potential to smooth the way from design to production, Robust Design, at the same time, appears to be an underdeveloped skill among design engineers. Our research has shown that interfaces and mechanisms with a lack of robustness frequently lead to excessive design changes and iterations, resulting in significant R&D resources spent after design freeze. Nonetheless, companies still rely largely on theses reactive quality control measures, i.e. late stage validation activities, the ever-increasing tightening of production tolerances, rigorous quality control procedures, etc.

In a new direction, the DTU Robust Design Group therefore strives to create awareness for the importance of variation, and to bring Robust Design thinking and research into earlier stages of development. Our main objective is to further the development of a coherent Robust Design Methodology, as well as a comprehensive Robust Design Method/ Toolbox that spans all product realisation phases, links different perspectives on variation (Design, Production, Metrology), facilitates the use of the nowadays commonly applied CAE tools, and exploits the benefits of new technologies and analytics.

Our research has been keep industrially relevant through its application in practice based on continuous industrial collaboration, as well as the international Special Interest Group (SIG), affiliated with the Design Society, where DTU holds the current chairmanship.
