What are the Severity Class and Failure Probability ratings scales for in Xfmea/RCM++?
A typical FMEA incorporates some method to identify and evaluate the risk associated with the potential problems identified through the analysis. Xfmea and RCM++ support both Risk Priority Numbers (RPNs) and Criticality Analysis. RPNs: To use the Risk Priority Number (RPN) method to assess risk, the analysis team must: • Rate the severity of each effect of failure. • Rate the likelihood of occurrence for each cause of failure. • Rate the likelihood of detection for each cause of failure. • Calculate the RPN by obtaining the product of the three ratings: RPN = Severity x Occurrence x Detection Criticality Analysis: To use the quantitative Criticality Analysis method, the analysis team must: • Define the reliability/unreliability for each item and use this to estimate the expected number of failures at a given operating time. • Identify the portion of the items unreliability that can be attributed to each potential failure mode. • Rate the probability of loss (or severity) that will resu
