IEEE Transactions on Reliability, 2013
The purpose of this paper is to enhance the study of the mean time to failure (MTTF) order in an age replacement model, and the decreasing mean time to failure (DMTTF) class of life distributions. We present new characterizations of the MTTF order in terms of the well-known hazard rate and reversed hazard rate orders.

Mean Time to Failure with Preventive Maintenance
IEEE Transactions on Reliability, 1980This paper considers a periodic pm (preventive maintenance) policy where pm reduces the age of an operating unit by x units of time. We obtain i) the mean time to failure and ii) the s-expected number of pm's before failure.

Comparison of mean time to first failure and mean up time
Microelectronics Reliability, 1983Abstract Two unit standby redundant repairable system, parallel systems and series systems are studied. The time between failures and the repair time are assumed exponentially distributed. Expressions for mean time to first failure (MTTFF) and mean up time (MUT) have been obtained.
