    Pacemaker reliability can be thought of as a measure of the change in quality during lifetime or mean time to replace (MTTR). Quality has been defined as the totality of all the features designed and built into a pacemaker, or any product. If these features are to function as intended for the designed MTTR, a formal quality system which covers design, qualification manufacturing, distribution and ... View full abstract»

    A failure mode and effects analysis (FMEA) seeks to determine how a system will behave in the event of a device failure. It involves the integration of several expert tasks to select components for analysis, determine failure modes, predict failure effects, propose corrective actions, etc. During an FMEA, numerical values are often not available or applicable and qualitative thresholds and linguis...

    In this paper, the authors suggest the consideration of destructive single-event latchup (SEL) as an additional failure mode for components in space systems. With this orientation, the failure rate for this process can be combined with the standard failure analysis to obtain a composite failure rate prediction. This paper shows how SEL can be included in the standard reliability formalism and how ... View full abstract»

    The design community has historically been challenged to design-in reliability and maintainability (R&M) during the front-end of the design process. This has been difficult due to the budget profiles on most programs: R&M activities have not traditionally been funded up-front, and the designers are usually just too busy trying to make their designs work to worry about R&M.

    The expanding size and complexity of dependable computing systems has increased their cost and at the same time complicated the process of estimating dependability attributes such as fault coverage and detection latency. One approach to estimating such parameters is to employ fault injection, however algorithms are needed to generate a list of faults to inject. Unlike randomly selected faults, a f...
