Variants of Solution and Evaluation of FMEA in Practice

Failure Mode and Effects Analysis (FMEA) is a model used to prioritize potential defects based on their severity, expected frequency, and likelihood of detection. An FMEA can be performed on a design or a process and is used to prompt actions to improve design or process. There is an uncertainty from manufacturers at present that the setting of criteria's of FMEA is subjective. There is another problem in determining the priority of resolving failure modes. The paper provides various options for prioritizing failure modes. At the same time, the individual methods specify the parameters for calculating the Risk priority number (RPN). We achieve objectification of criteria's for RPN calculation in FMEA. These are time-consuming and cost-effective designs. The proposed innovations are an extended RPN, including the creation of an extended FMEA and the use of the DEMATEL model.
