The Fuzzy Failure Mode and Effect Analysis (FMEA) Method to Improve Roofing Product’s Quality (case study : XYZ Company)

Abstract

Abstract Evaluation and improvement of production performance are things that must be considered in an effort to maintain and improve the quality of production results. One level in measuring production performance is smooth production. Good risk management can support and maintain the smooth production process in the company. This research was conducted at PT XYZ with the aim to reduce the risk of failure of zinc products and propose improvements to the risk of product failure to improve the quality of zinc products. The method used in this case is Fuzzy FMEA (Failure Mode and Effect Analysis). Fuzzy logic approach is preferred to eliminate this shortcoming in setting risk priorities number. The use of the Fuzzy FMEA method can generate priority figures for failure modes so that problems can be solved efficiently in an effort to improve production performance. The results of this study are failure modes. One of the rollers got the highest FRPN value of 880,289 so that failure due to incorrect grinding machine settings and the lack of operator accuracy in positioning zinc was recommended as a major improvement to minimize milling error failures in the production process.
