When assessing the reliability of a system, a mathematical model is often defined to replicate the system?s behavior. The inputs of the system are then gathered into two categories, random inputs and deterministic inputs. The failure of the system depend...

Reliability-based design optimization (RBDO) has become a prevalent design for aeronautical and aerospace engineering. The main problem is that it is impractical in complex cases with multi-failure regions, especially in multi-objective optimization. The...

This paper proposes a reliability-based design optimization (RBDO) approach that adopts the second-order reliability method (SORM) and complex-step (CS) derivative approximation. The failure probabilities are estimated using the SORM, with Breitung?s for...
