Multiple fault diagnosis method in multistation assembly processes using orthogonal diagonalization analysis

A key issue during launch of a new production system is lack of rapid root cause identification of 6-sigma product failures. This results in significant delays and cost, e.g., there are ~6,000 engineering changes during launch of a new automotive body assembly system. To date, the identification of process-related faults that cause 6-sigma failures remains one of the most critical research topics in dimensional control. A novel approach is presented for multiple 6-sigma fault diagnosis. The approach is used by GM (wayne.cai@gm.com) and DCS (djohnson@3dcs.com). It is Top-3 most cited paper among all 594 papers published in the journal 2008-2013.
