This research compares Taguchi's crossed array approach with the combined array approach (an alternative proposed by statisticians) using an experiment designed to optimize the sewing conditions to minimize the variability of a high end women's garment. The optimum settings given by the two approaches were similar, although the combined array approach provided more information about the process with a slightly better parameter setting. The findings imply that the benefit an apparel organization gets in conducting a statistically sophisticated analysis needs to be carefully weighed against the statistical simplicity Taguchi's crossed array approach offers in robust parameter designs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
