    Mean time between failures (MTBF) indicates how long any equipment is expected to operate reliably. It is derived by computing the average time between failures for that piece of equipment. Obviously, the higher the MTBF, the better.
    MTBF, of course, assumes that the equipment can be repaired. If it cannot be repaired, the term MTTF (mean time to failure) is used.
    Mean time to repair (MTTR) is the average time to repair a piece of equipment and put it back into production in case of failure. Here, the smaller the MTTR the better.
