This paper proposes a distributed UMDO architecture based on surrogate models to enable the UMDO problems to be solved. The architecture decouples uncertainty analysis and optimization, and surrogate models can quickly evaluate discipline performance and uncertainties. The liquid launch vehicle case is performing to validate the proposed architecture.
