WebHow to Improve MTBF. Many factors affect your MTBF calculation, such as age, operating conditions, and usage patterns. However, the calculation can be improved by reviewing the systems and making the appropriate changes. Process Improvements. One method to improve MTBF is through process improvements. WebTherefore, if we don't know the real MTBF figure, and our 1.000 h test produces 2 failures, the best guess for the average number of failures within 1.000 h would be 2,68, which transforms into the best guess MTBF = 1.000h / 2,68 = 373 h. Note that randomness (failures occurring randomly) is the cause for this. tales of reincarnation in maydare chapter 26
