Annualized Failure Rate (AFR)
Annualized Failure Rate (AFR) is a metric used in maintenance operations and management to measure the reliability of a system or component over a given period of time. It is calculated by dividing the total number of failures in a year by the total number of operating hours in that year. AFR is expressed as a percentage and is used to identify potential problems and prioritize maintenance activities. AFR is an important metric for maintenance operations and management as it helps to identify areas of improvement and ensure that systems and components are operating at optimal levels. It is also used to compare the reliability of different systems and components, allowing for informed decisions to be made about maintenance activities.
