MTBF

MTBF (Mean Time Between Failures) (平均故障間隔)

MTBF is an optional input variable (Parts, or End Item/Part Data), required in the event that no value has been provided for MRR6.

MTBF values are converted to MRR6 whenever no data have been entered in that field. 

MRR6 is the expected interval, in hours of operation, between failures. It is the inverse of the failure rate. The value entered should have been adjusted for environmental degradation, but not for repair in place, conversion factor or no fault found effects.
