MTTF-Aware Design Methodology of Adaptively Voltage Scaled Circuit with Timing Error Predictive Flip-Flop [PDF]

open access: yes, 2019
Adaptive voltage scaling is a promising approach to overcome manufacturing variability, dynamic environmental fluctuation, and aging. This paper focuses on error prediction based adaptive voltage scaling (EP-AVS) and proposes a mean time to failure (MTTF)

Reliability Analysis of Random Fuzzy Unrepairable Systems

open access: yesDiscrete Dynamics in Nature and Society, 2014
The lifetimes of components in unrepairable systems are considered as random fuzzy variables since randomness and fuzziness are often merged with each other.

Is it safe to use MTTF/(MTTF + MTTR) for the availability?

open access: yes, 2019
International audiencePractitioners in reliability and system safety know that the asymptotic availability of a repairable component is given by the ratio MTTF/(MTTF + TMTR). The transient behavior of the availability is less well known.

Temperature-Driven Reliability Analysis of Power Grid Failures: A Weibull Distribution Approach To Outage Prediction and Mitigation

open access: yesJournal of Statistical Theory and Applications (JSTA)
This study aims to elucidate the critical relationship between temperature variations and power outages. We propose to employ the Weibull distribution, a fundamental tool in reliability analysis, to assess the impact of temperature on power grid failures

On Derivative Estimation of the Mean Time to Failure in Simulations of Highly Reliable Markovian Systems

open access: yes, 1998
The mean time to failure (MTTF) of a Markovian system can be expressed as a ratio of two expectations. For highly reliable Markovian systems, the resulting ratio formula consists of one expectation that cannot be estimated with bounded relative error ...

Approximate estimation of reliability, mean time to failure and optimal redundancy of fault-tolerant processor arrays

open access: yes, 1990
Fault-tolerant schemes are very important for processor array design because there is a high probability of failure of one or more processors in an processor array of large size.
