COMPARISON STUDY: TAGUCHI METHODOLOGY VIS.-A-VIS. RESPONSE SURFACE METHODOLOGY THROUGH A CASE STUDY OF ACCELERATED FAILURE IN SPIN-ON-FILTER

Abstract: In this paper we investigate the choice of best combination of factors for 27 X 31 mixed factorial design in 16 runs through Taguchi Design Method and Response Surface Method (RSM). Further we show that Response Surface Method predicts better optimal response (9.72% more) as compared to optimum response obtained through Taguchi Design Method. The comparison of methods is done with the help Spin-on-Filter case study conducted by [1]. We use MINITAB for the analysis under both methods.
