An Efficient Method for Reliability-based Multidisciplinary Design Optimization

Fan Hui, Li Weiji
2008 Chinese Journal of Aeronautics  
Design for modern engineering system is becoming multidisciplinary and incorporates practical uncertainties; therefore, it is necessary to synthesize reliability analysis and the multidisciplinary design optimization (MDO) techniques for the design of complex engineering system. An advanced first order second moment method-based concurrent subspace optimization approach is proposed based on the comparison and analysis of the existing multidisciplinary optimization techniques and the reliability
