The purpose of this study is to compare three different methods for prioritizing failure modes in a design FMEA study. These methods are traditional approach, Grey Relational Analysis GRA- under the assumption of risk factors having equal weights and integration of Grey Relational Analysis and Fuzzy Analytic Hierarchy Process FAHP -to estimate weights for the risk factors-. According to the findings, integration of Grey Relational Analysis and fuzzy AHP revealed a difference in prioritizing failure modes from the methods with the assumption of equal weights. Because this method eliminates some of the shortcomings of the traditional approach, it is a useful tool in identifying the high-priority failure modes.
