Probabilistic Design and Analysis for System-Level Application

This paper focuses on the computation of system reliability and its application to probabilistic design. While success has been reported with methods for individual components and failure modes, integrating them to estimate overall system-level reliability faces several hurdles, such as integration across multiple levels and multiple physics. Computational effort is a major challenge, especially when evaluating reliability over time and considering progressive damage and interactions among multiple failure mechanisms. This paper discusses techniques to overcome some of these challenges, considering trade-offs between accuracy and efficiency.
