Supporting Preliminary Design Decision Making with A Risk Data Base

摘要

Attribute identification, class assignment, and the development of correspondences of classes of attributes to ranges of reliability measures are critical to the proper development and application of reliability data. The proper assignment of attribute classes can allow for the establishment of reasonable estimates of the credible range to be expected for reliability measures for devices even if they are not yet existent, or for devices whose reliability measures are unknown to the analyst as long as their attributes can be brought into correspondence with known device attribute classes. 'Proper class structuring of a database allows reliability measures to be applied, albeit within a range of uncertainty, so as to be useful during the preliminary design stages where the elements of the design- are necessarily conceptual and reliability measures provide significant value needed to the designer.
