Risk Times in Mission‐Oriented Systems

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 1380-1398, April 2026.
ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.
