항공기 구조성능 향상을 위한 신뢰성기반 최적설계

This paper presents the reliability based design optimization(RBDO) for air structure. We utilized central composite design(CCD) of experiment design method and response surface method(RSM) to generate the response surface that describes limit state function for design constraint. And we ontain reliability index(β) using advanced first-order second-moment method(AFOSM).
