Reliability Assessment of a Series System with Weibull-Distributed Components Based on Zero-Failure Data

open access: yesApplied Sciences
This study focuses on the reliability assessment of a series system composed of Weibull-distributed components. Because high-reliability components rarely fail during life testing or actual operation, conventional system reliability analysis methods ...
