Journal of Industrial Engineering International, 2017 In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence ...

Mean Time Between Failure of Ring Arbiter with Requests Differing in Incidences [PDF]
, 1990 In asynchronous arbiters, failures may happen, caused by metastable operations. The purpose of this study is to derive a formula to estimate such failures in a ring arbiter as mean time between failures (MTBF), under the condition that incidences of ...

Degradation Analysis of Probabilistic Parallel Choice Systems [PDF]
, 2014 Degradation analysis is used to analyze the useful lifetimes of systems, their failure rates, and various other system parameters like mean time to failure (MTTF), mean time between failures (MTBF), and the system failure rate (SFR).

Reliability modelling of uninterruptible power supply using probability tree method [PDF]
, 2006 The unreliability of public power lines have led to the need of uninterruptible power supply (UPS). Utility power failures will cause unacceptably high risk to the profitability, existence and growth of the vital aspect of business that depends heavily ...

Reliability Calculation for Dormant k-out-of-n Systems with Periodic Maintenance [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2016 In this paper, a dormant k-out-of-n systems redundancy calculation will be introduced. Dormant failure is a failure that cannot be detected when it occurs because of the nature of the failure characteristic. Therefore, a dormant failure becomes the blind
