The mean time between failures for an LCD panel

Quality and Reliability Engineering International, 2011
AbstractThe calculation of mean time between failures is very important in reliability life data analysis. For different distributions, the values of mean time between failures are always different. The two‐parameter Weibull distribution is widely used in reliability engineering. However, some distributions may offer a better fit of data.

Sequential Test for Arbitrary Ratio of Mean Times Between Failures

International Journal of Operations Research and Information Systems, 2011
This paper describes a planning methodology and tools for a truncated SPRT (sequential probability ratio test) for checking the means ratio of the times between failures (assumed to be exponentially distributed) of two items. The problem is considered for the situation in which the ratio may differ from unity, whereby the results are applicable for any

Sequential Testing for Comparison of the Mean Time Between Failures for Two Systems

IEEE Transactions on Reliability, 2007
This study deals with simultaneous testing of two systems, one "basic" (subscript b), and the other "new" (n), both with an exponential distribution describing the times between failures. We test whether the mean TBFn/MTBFb ratio equals a given value, versus whether it is smaller than the given value. These tests yield a binomial pattern.

`Mean Time Between Failures': A Subjectively Meaningful Video Quality Metric

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
As digital communication of television content becomes more pervasive, the long-standing problem of assessing video quality becomes particularly important. This work describes some innovative guidelines for easy and reliable determination of a quality metric that is subjectively meaningful: mean time between failures (MTBF), representing how often a ...

Control of mean time between failures

International Journal of Control, 1994
A new optimal stochastic control problem is posed. The criterion is to maximize the mean-time-between-failures criterion given a certain reference value. It is shown that this control problem is closely related both to the problem of minimizing the variance of the signal—minimum variance control — and to the problem of minimizing the so-called ...

An assessment of mean time between failures for a group of rolling bearings

2011 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2011
Rolling bearings are usually considered to be non-repaired items the reliability of which is characterized by mean time to failure, or so called basic rating life. Reliability describes these parameters well in case the bearings are used in operation up to the very time the failure occurs, or during the time corresponding with basic rating life.

Assessing tracking performance in complex scenarios using mean time between failures

2016 IEEE Winter Conference on Applications of Computer Vision (WACV), 2016
Existing measures for evaluating the performance of tracking algorithms are difficult to interpret, which makes it hard to identify the best approach for a particular situation. As we show, a dummy algorithm which does not actually track scores well under most existing measures.

Comparison of the Mean Time Between Failures for Two Systems Under Short Tests

IEEE Transactions on Reliability, 2009
A sequential probability ratio test (SPRT) is discussed, for comparison of two systems, one "basic" (b), and the other "new" (n), with exponentially distributed times between failures (TBF). The hypothesis that the mean TBFn/MTBFb ges 1 is checked, versus one that it is

Assessment of mean time between failures of metrological support and control of production

2014 12th International Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2014
Any parametres have a relevant Annotation - mean time between failures diminishes in the process of system activity before some minimum value, corresponding to a set stationary process of restoration. This fact causes necessity to study in detail issues relating to stability of systems to support efficient functioning of metrological systems.

Bayesian estimation of the difference between two mean times to failure

Stochastic Analysis and Applications, 1992
This paper is concerned with the problem of allocating a fixed number of trials between the failure times of two independent components with unknown mean times to failure , in order to estimate with squared error loss. Introducing independent gamma priors on θ and ω, a fully sequential procedure is derived and shown to be nearly optimal.
