A review of practices for robust design methodology
Journal article, 2009
Robust Design Methodology (RDM) comprises systematic efforts to achieve insensitivity of products or processes to sources of unwanted variation. In this paper we review the literature and identify practices that facilitate industrial use of RDM by providing concrete ideas about what to do in order to come up with more robust designs. So far the literature has focused mainly on statistical techniques useful for creating robust designs, i.e. solutions that are insensitive to sources of unwanted variation, while scope and overall framework have been less emphasized, causing an ambiguity in these respects. One practice identified for insensitivity to variation sources is to exploit nonlinearities (between response and control factors) and interactions (between noise and control factors), and suitable tools for accomplishing this can be design of experiments or simulation techniques. As systematic RDM efforts are based on an awareness of variation and are beneficial in all design stages, the review also focuses on these two aspects of RDM.
