In this paper we propose a novel method for effective and efficient reliability-focused parts selection in time-driven derivative product development processes (PDP), synthesized by employing the Reliability and Quality Matrix (RQM) in conjunction with the Utility-based selec. lion Decision Support Problem (U-sDSP). The U-sDSP is a powerful multi-attribute utility analysis method that facilitates the selection of parts, based on quantitative reliability and cost estimates, under conditions of risk and uncertainty. In order to meet the stringent information requirements of the U-sDSP, however, an effective means for quautifying the uncertainty, resulting from imperfect information associated with reliability analysis, is required. RQM fulfills this need by modeling the effect of part reliability O n product reliahil. ity including (he aspect of uncertainty. The resulting decision support method leverages the respective advantages pertaining to each of the two constructs and is applied to a simple catalogue-based design process, focusing on the COO. figuration of a suitable motor configuration (i.e., motor, pinion, etc.), assembled using a pre-specified process.
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.
