A New Technique for MTTF Estimation in Highly Reliable Markovian Systems
Monte Carlo Methods and Applications, 1998A new method for the importance sampling simulation of highly reliable Markovian systems is presented. The method has the bounded relative error for balanced and under an additional assumption, unbalanced systems. It has shown very high efficiency in the estimation of the mean time to failure (MTTF) of a system, which is a measure of great importance ...

Welding Process under Fault Coverage Approach for Reliability and MTTF
2017This chapter deals with the problems occur in the welding under the consideration of many causes of defects such as cracking, distortion, porosity, inclusion and undercutting. Welding is very useful for every industry. It is used as a fabrication and sculptural that joins the two parts of materials, generally metals or thermoplastic, through a ...

Reliability and MTTF evaluation of a repairable complex system under waiting
Microelectronics Reliability, 1987Abstract This paper deals with the reliability and mean time to failure (MTTF) evaluation of a complex system under waiting incorporating the concept of hardware failure and human error. Failure rates of the complex system follow exponential time distributions, whereas repair follows a general repair time distribution.

MTTF: Multidimensional Time & Matter Framework
The Multidimensional Time–Matter Framework (MTTF) proposes that the observable universe emerges as a Gaussian projection of a six-dimensional atemporal manifold with SO(3,3) symmetry.In this framework, physical time and matter arise from the same geometric process of dimensional reduction through a Gaussian kernel Kσ(t2)K_\sigma(t_2)Kσ(t2), yielding anopenaire +1 more source
Passivation Material and Thickness Effects on the MTTF of Al-Si Metallization
23rd International Reliability Physics Symposium, 1985Different passivation materials, namely undoped oxides (plasma and non-plasma deposited), P-doped oxide (PSG), oxynitride and their sandwiches were used to passivate the Al-Si test structures. MEF data (correlated to MTTF) were obtained from the wafer level test method called BEM (Breakdown Energy of Metal) which is presented separately in this ...

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.

MTTF Prediction in Design Phase on Thales Cryogenics Integral Coolers
2002A continuous improvement of Stirling integral coolers MTTF is necessary to answer the new market requirements. The time spent in the design phase is critical to get the product ready at the right time and to reduce the development costs. In order to reduce the development risks (be sure to get in the new design at a higher MTTF), we have developed a ...

Computing Bounds of the MTTF for a Set of Markov Chains
2013We present an algorithm to find some upper and lower bounds of the Mean Time To Failure (MTTF) for a set of absorbing Discrete Time Markov Chains (DTMC). We first present a link between the MTTF of an absorbing chain and the steady-state distribution of an ergodic DTMC derived from the absorbing one.
