WebNov 4, 2024 · The second issue takes 2 hours to repair, leaving 58 (140 - 76) hours of uptime. The values utilized in the MTBF formula is as follows: MTBF = (40 hours + 36 hours + 58 hours) ÷ 2 failures. MTBF = (134 hours) ÷ 2 failures = 67 hours. MTBF = 67 hours. We can now see that the MTBF is equal to the total uptime for a particular device or system. WebThe failure rate predicts the average number of hours that an item, assembly, or piece part will operate before it fails, while the MTBF predicts the average elapsed time between failures. Jones posits that the MTBF of an item is often used in calculating spares requirements, Life Cycle Cost (LCC) and other failure related data. me and robin hood radio 4
