AN APPLICATION FOR THE FAILURE MODE AND EFFECTS ANALYSIS INTEGRATED WITH THE GREY RELATIONAL ANALYSIS
Abstract
Although the Failure Mode and Effects Analysis (FMEA) is a systematic method of analysis, it has some shortcomings and limitations since it is a method based on intuitionistic and subjective statements of the person that rate the failure modes. In order to eliminate these constraints, the use of the method in conjunction with the grey relational analysis, which is one of the multi criteria decision making methods, helps to eliminate intuitionistic situations and prioritize the failure modes that need corrections and precautions.
The classical FMEA and the FMEA integrated with the grey relational analysis approaches were applied, and their effectiveness was assessed in this study to identify and prioritize the failures and determine the measures to be taken in the wheat sieving machine production. For this purpose, first the Risk Priority Numbers (RPN) were calculated using the classical failure mode and effects analysis, then two separate grey RPNs were calculated on the assumptions that risk factors have either equal weight or different weight in the grey relational analysis-integrated FMEA approach, and the prioritization of the failures was performed. Three different RPN values obtained in the study were compared, and the priority optimizations to be made were recommended in order to prevent failures before reaching the customers as well as drawing the necessary conclusions accordingly.
