MTBF stands for Mean Time Between Failures and is a metric used to measure the reliability of a system or component. It is defined as the average time that a system or component can be expected to function before it fails. MTBF is calculated by dividing the total operating time of a system or component by the number of failures that occur during that time. MTBF is an important metric for assessing the reliability of a system or component and can be used to identify areas for improvement. MTBF is also used to compare the reliability of different systems or components and to determine the cost of mainmaintenance and repair. By understanding the MTBF of a system or component, organizations can make informed decisions about how to improve reliability and reduce costs.
