The pilot application results suggest that “fading time exceeded” and “chemical composition outside of the specified” should be treated with highest priority.
The experts also chose the criteria and their respective weights. Based on the opinion of four company experts, potential failure modes were defined and assessed. A pilot application was performed to analyze and prioritize the risks of potential failures in a nodular iron melting and casting process. This study proposes a model based on FMEA and Fuzzy TOPSIS to support risk prioritization in industrial production processes. With the objective of adding new features to FMEA, some studies combine it with multicriteria decision methods. Nonetheless, this method has some limitations, including the use of only three decision criteria, whose weights are not considered. FMEA is one of the most used methods to support risk analysis in business processes.
