Subject: Reliability Prediction on different environment
Message:
Hi, I need some advise on the reliability prediction. If I uses the MTBF predicted for Ground Fixed environment in Ground Mobile environment, that means that I have to degrade the MTBF by a factor of 0.2 as refered in the Reliability Toolkit for Commerical Practices. However, as the equipment will be ruggedised and isolator and shock pad are included to minimise the vibration and shock level, does that means that the factor of 0.2 does not stand anymore and I can asssume that the MTBF of GF is more or less equivalent to GM.
