The Robust Classical MTBF Test

The ITEA Journal of Test and Evaluation
For the reliability demonstration of a repairable system, testers expediently assume that the rate of occurrence of failures (ROCOF) can be modeled by a homogenous Poisson process (HPP), also called an ordinary renewal process (ORP), and therefore the times between failure, or interarrival times, are exponentially distributed with a constant mean time ...

A Design Margin Index for MTBF and Ao

2007 Proceedings - Annual Reliability and Maintainability Sympsoium, 2007
The purpose of capability growth index is to give designers and development managers an early heads-up as to where they stand in achieving the metric under scrutiny, such as MTBF. The Capability Growth Index measure is based on the widely used quality process capability indices, Cp and Cpk.

Analysis of MTBF/MTTR for Logistics Service System

ICTE 2013, 2013
Mean Time Between Failures/Mean Time to Repair (MTBF/MTTR) are important parameters for measuring the reliability of systems. Shorter MTBF/MTTR normally means high service quality. However, a reasonable level of reliability is usually not defined. In this paper, the calculation method of MTBF/MTTR is presented.

On comparison of MTBF between four redundant systems

Microelectronics Reliability, 1993
Abstract In this study we compare the mean time between failures (MTBF) of four series-parallel and parallel-series redundant systems composed of 2 n independent components. General ordering relations between the four systems in terms of their MTBF are obtained. These results substantially improve previous ones obtained by Yamashiro etc.

MTBF warranty/guarantee for multiple user avionics

Annual Proceedings on Reliability and Maintainability Symposium, 2002
A MTBF (mean time between failures) warranty/guarantee situation is modeled for an avionics unit installed on different platforms and subjected to varying levels of operational stress. The demand for warranty repairs is approached by structuring submodels and solving these submodels using linked spreadsheets.

MTBF specification in a multiple use environment

1988. Proceedings., Annual Reliability and Maintainability Symposium,, 2003
A criterion, in the form of an equivalent failure rate equation, is developed which allows for the mean time between failures (MTBF) specification of a configuration item that is used in different environments and subject to a varying amount of operational stress.

Estimating warranty and service costs from MTBF estimates

Proceedings of Electro/International 1995, 2002
What is the cost of warranty? What is the cost of service? What are the cost trade-offs between product reliability and sell price? In today's aggressive marketplace with shrinking profit margins and shorter product introduction times these questions are being asked earlier in the product design cycle.
