Abstract

In Robust Design literature, the application of Robust Design guidelines is suggested as a measure to obtain a design that is more insensitive against variations. But it lacks a detailed and systematic overview of already existing design advice that can be transferred to robust design tasks. The authors provide a literature investigation of design advice in engineering design literature, derive criteria to assess its applicability for robust design tasks based on transfer functions and noise behaviour models. The research shows that almost half of the existing design advice is also suitable for robust design. To include the design advice catalogues into the development process, the authors suggest a procedure that is allocated within the integrated product and process development process. It consists of opportunistic analysis and synthesis steps and should be applied up from working principle level. To quantify the potential of robust design advice application, the robustness potential indicator is introduced. It represents the degree of robust design advice consideration.
