The SL-AVV approach to system level reliability-based design optimization of large uncertain and stochastic dynamic systems Spence, Seymour M. J.


Recently a number of efficient reliability-based design optimization methodologies have been proposed for optimizing uncertain dynamic systems subject to stochastic excitation. While these methods are capable of handling a large number of uncertain parameters, they are generally applicable to problems characterized by small design variable vectors. This paper focuses on the development of a new reliability-based design optimization methodology for uncertain dynamic systems subject to stationary stochastic wind excitation that is capable of handling large design variable vectors, a characteristic of many practical design problems, while considering system level performance constraints.
