Abstract

"Motivated by the need of high reliability and safety in complex engineering systems, recently reliability-based design has been increasingly applied in multidisciplinary design optimization (MDO). However, a direct integration of reliability-based design that has been successful in many single disciplinary fields into MDO may present tremendous implementation and numerical difficulties. The reliability analysis and reliability based designs are highly expensive for MDO considering various disciplines that are dependent on each other or coupled. Hence, the present work proposes a methodology of Sequential Optimization and Reliability Assessment for multidisciplinary systems design, to improve the efficiency of reliability-based MDO. The central idea is to decouple the reliability analysis from MDO with sequential cycles of reliability analysis and deterministic MDO and hence to reduce the computational demand"--Abstract, page iii.
