| Abstract: |
| Complex engineering system usually involves coupled multi-discipline and uncertainties.A new approach for reliability design of multi-disciplinary system is proposed,in which uncertain variables are described by convex model and sequential optimization,and reliability assessment method are used as optimization strategy.The reliability analysis method is performance measure approach,and multi-disciplinary feasible method or bi-level integrated system synthesis method is used to optimize the multi-disciplinary system.A numerical example and an engineering problem were solved by the approach to demonstrate its effectiveness.Compared with the conventional inner-loop method,the computational efficiency is higher.Therefore,the novel approach is likely applied in reliability design for complex engineering system. |
