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 ...

Computing the Availability and MTTF of Shared Protection Systems
7th IEEE International Conference on Computer and Information Technology (CIT 2007), 2007In this paper we investigate the reliability of shared protection systems such as one for N (1:N) that can be applied to access network node devices. We describe the effectiveness of such a protection system in a quantitative manner. The mathematical analysis gives closed form solutions of the availability and MTTF (Mean Time to Failure) perceived by ...

Is it safe to use MTTF/(MTTF + MTTR) for the availability?
Proceedings of the 29th European Safety and Reliability Conference (ESREL), 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.

MTTF: a multimodal transformer for temperature forecasting
International Journal of Computers and Applications, 2023Accurate weather forecasting is crucial for various applications, including agriculture and environmental monitoring. However, existing deep learning based methods typically use only temperature observations as input, which do not consider spatial ...

MTTF-aware design methodology for adaptive voltage scaling
2018 China Semiconductor Technology International Conference (CSTIC), 2018Adaptive voltage scaling (AVS) is a promising approach to overcome manufacturing variability, dynamic environmental fluctuation, and aging. This paper focuses on design of AVS circuits. For pursuing efficient AVS, this work presents a design methodology that optimizes both voltage-scaled circuit and voltage control logic achieving practical long mean ...

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.

MTTF-Aware Reliability Task Scheduling for Heterogeneous Multicore System
International Conference on Algorithms and Architectures for Parallel Processing, 2015With silicon technology aggressively scaling, the aging-induced long-term reliability becomes the prominent problem of integrated circuits. The reliability of homogeneous multi-core system is improved and the aging is relieved through balancing the workload between cores.

A Method for the Calculation of the Mean Time To Failure (MTTF) of Repairable System
Advanced Materials Research, 2008The ability of executing assigned function of repairable system under certain condition is quite different from that of single unit due to redundant configuration. It is well understood that proper management strategy can greatly prolong the mean time to failure (MTTF) of repairable system.

Conditional MTTF and its computation in Markov reliability models
Annual Reliability and Maintainability Symposium 1993 Proceedings, 2002The authors discuss the notion of conditional MTTF (mean time to failure) and develop an efficient computational method for the absorption probability and conditional MTTF in a finite state-space Markov model. The method requires the solution of two systems of linear equations of size n, where n is the number of transient states in the Markov chain ...

Analytical method for reliability and MTTF assessment of coherent systems with dependent components
Reliability Engineering & System Safety, 2007This paper discusses engineering systems with structural as well as failure dependence among their components. Using the Markov process approach, a coherent system of components with multivariate phase type life distribution is introduced to model the components working in a common random environment. The phase type model is flexible enough to comprise
