Analysis of conditional MTTF of fault-tolerant systems
Microelectronics Reliability, 1998Mean time to failure (MTTF) is one of the most frequently used dependability measures in practice. By convention, MTTF is the expected time for a system to reach any one of the failure states. For some systems, however, the mean time to absorb to a subset of the failure states is of interest.

General solutions for MTTF and steady-state availability of NMR systems
2014 9th International Symposium on Reconfigurable and Communication-Centric Systems-on-Chip (ReCoSoC), 2014Voting redundancy is a well-known technique to improve the fault tolerance of digital systems. Calculation of reliability and availability is a necessary part of every fault tolerant system design. Conventional techniques, including block diagram method, are unsuccessful when there is dependent failure, repair, or standby operation in the system.

Benefits of Finer Semiconductor Device Granularity on Power Converter Thermal Stress and MTTF
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021This article explores the thermal and reliability benefits of configuring the power semiconductor block of power converters with several small standard power semiconductor devices instead of a few larger ones at a fixed total chip area. The effectiveness of a finer power semiconductor device granularity is analyzed in the context of a synchronous buck ...

Quantitative analysis of MTTF of composite web services
Journal of the Chinese Institute of Engineers, 2013Although the reliability of the composition of web services (WS) has attracted much research work, an important facet of it – meantime to failure (MTTF) has not been given enough consideration. The research presented in this paper intends to fill this gap by illustrating on an example of composite WS how the redundant system works and what kinds of ...

Exploiting Dynamic Platform Protection Technique for Increasing Service MTTF
2019 IEEE Global Communications Conference (GLOBECOM), 2019Moving Target Defense (MTD) technology protects a target system by complicating the attacking process of adversaries. It has been gaining more and more attention with the massive growth of vulnerabilities and the widespread deployment of critical network services.

Evaluation of MTTF and reliability of a power plant by BF technique
Microelectronics Reliability, 1986In this paper, investigations have been carried out for the evaluation of reliability and MTTF (mean time to failure) of a parallel redundant complex system; viz. a power plant. The object of the system is to supply power generated by generators from a power house to a very important consumer, connected by cables and switches.

Usefulness of MTTF of s-independent case in other cases
IEEE Transactions on Reliability, 1992It is a plausible conjecture that for many cases of statistical dependence, the system MTTF (mean time to failure) is nearly that for statistically independent components. The author deals with Markov k-out-of-n:F systems, for which the degree to which the above conjecture is true could be clarified satisfactorily.

Choosing a Practical MTTF Model for ECC Memory Chip
Annual Reliability and Maintainability Symposium, 1984. Proceedings., 2005This paper presents an assessment and evaluation of the leading memory chip error correction code (ECC) reliability prediction models. Criteria was developed and applied to four of the currently most popular ECC memory chip reliability models. The characteristic analysis, reliability prediction models and modifications to these reliability prediction ...

MTTF and MTFF of a k out of n system
Microelectronics Reliability, 1987Abstract The distributions of operating and repairing time of a k out of n system are analysed when the system reaches the steady state. The MTTF would be a lower bound for the MTFF if the system starts at a state where all components are operating like new.
