System Reliability | Dr. Emre Yılmaz

The prior information at the basic event levels can vary notably in fault trees.
An approach for uncertainty propagation via statistical moments is developed.
The approach depends on the distribution types when dependencies exist.
Sensitivity analysis is leveraged for optimizing resource allocations.
Constrained optimization problems are formulated to improve system safety.
The optimization problem is solved using augmented Lagrangian approach.
