Businesses apply various strategies to increase customer satisfaction and to get ahead of their competitors in the market. One of the methods used within the framework of this strategy is the Failure Mode and Effects Analysis (FMEA) method, which enables the discovery of errors in products or services before they occur. In the FMEA method, the severity, probability and discoverability of potential errors are determined and scored. However, it is possible to state that the FMEA method may be insufficient in cases where more sensitive analysis is required due to the limited nature of the measures used in the scoring process. In order to prevent this, a hybrid study was conducted in which a new ranking was made using classical FMEA and multiple fuzzy multi-criteria decision making techniques. In the literature, no study has been found in which more than two fuzzy multi-criteria decision making techniques have been used, and it is aimed to reach the most accurate result by using 5 different methods by eliminating the disadvantages of each method. This study was carried out in the heat treatment process of the fasteners industry, and in addition to classical FMEA, errors were listed with DEMATEL-weighted, fuzzy TOPSIS, fuzzy VIKOR, fuzzy Gray Relational Analysis and fuzzy MOORA methods. As a result of the 5 rankings, a new model was developed and the final ranking was made.
