in manufacturing processes. The study of special-cause failures could also benefit from separate treatment for modeling and prediction.


As is true with most workshop reports, this report is intended to capture the flavor of the workshop and highlight its primary and most useful ideas and discussion. While the report does not represent a comprehensive transcript of the proceedings, it should certainly serve as a helpful guide to current trends in reliability research and practice that have special relevance to DoD applications. We recognize that much more could be said on statistical modeling, reliability, and system development, perhaps delving into such topics as experimental design for reliability measurement, estimation of reliability for highly reliable systems (so that the probability of not observing a failure during testing is sizable), complications posed by destructive measurements, repeated measure degradation studies, analysis of recurrent events, and use of simulation-based techniques. Perhaps some or all of these topics will be addressed in future workshops in this proposed series.

The next chapter examines methods for measuring and managing reliability growth that were presented at the workshop. This is followed by a chapter on important areas of current research in reliability modeling and inference. The final chapter presents a general discussion of reliability issues and examines the need, expressed on several occasions during the workshop, to disseminate well-understood, broadly applicable methods for reliability test and evaluation, possibly through a comprehensive overhaul of the RAM Primer and other DoD documents that focus on reliability.
