Screening for Noise Variables
Robust design seeks to create manufacturing processes which are insensitive to the effects of variability in uncontrollable variables. Current approaches to noise variable discovery are too little too late as they do not consider an adequate number of potential noise variables. Screening is done at a late stage of process development when process changes are very expensive. This paper presents some broad approaches to noise variable discovery using alternative modes of designed experiments and, as an alternative, analysis of historical data.
