MTBF evaluation for 2-out-of-3 redundant repairable systems with common cause and cascade failures considering fuzzy rates for failures and repair: a case study of a centrifugal water pumping system

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 ...

MTBF Bounds for Multistage Synchronizers

, 2013
— Synchronizers are used to mitigate the effects of metastability in multiple clock domain System-on-Chip devices. In order to enable reliable synchronization, the synchronizer MTBF (Mean Time Between Failures) should be much longer than the product ...

Reliability modeling and analysis of cycloid gear grinding machines based on the bootstrap-bayes method

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2023
To increase the reliability of cycloidal wheel grinding machines, reduce the failure rate of machine tools, and shorten maintenance times, a reliability modeling method for small-sample fault data is proposed based on the Bootstrap-Bayes method. The mean

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 ...
