Showing papers on "Intra-rater reliability published in 1974"
TL;DR: This paper presents the optimal design of tests for demonstrating the reliability of a system, assuming that all the subsystems have a very high reliability so that no failure is expected to occur during the tests.

TL;DR: In this paper, the importance of reliability is discussed and simple statistics about the reliability of a system are discussed. But reliability is not defined in detail, and the effect of operating conditions and environments is not discussed.

TL;DR: In this article, the authors investigated the effect of scale complexity and rater training on intra-rater reliability and found that neither rater experience nor scale complexity significantly influenced intra rater reliability.
Abstract: This article reports two studies which investigated the effect of scale complexity and rater training upon intra‐rater reliability. The results indicate that neither rater experience nor scale complexity significantly influenced intra‐rater reliability.

TL;DR: It is shown that reliability is so dependent on such factors that design for prescribed levels of reliability presents formidable difficulties, and how realistic theory supports everyday practical experience is noted.
Abstract: This paper is a subjective summary of nine conferences on quality and reliability organized by the Institution of Mechanical Engineers during the last decade. Starting from economic factors, optimum design is identified with minimum total life cost, which is, in turn, closely related to reliability. The paper examines reliability theory briefly for its practical implications, e.g. that reliability depends crucially on safety margin and loading roughness. The former is a design feature, but both are operator controlled. The matching of design to the requirements of the user in the intended environment is considered paramount. It is shown that reliability is so dependent on such factors that design for prescribed levels of reliability presents formidable difficulties. The design process is discussed, taking these and maintenance constraints into account. The necessity for proper development is underlined. It is noted how realistic theory supports everyday practical experience. Finally, the function of manag...
