Abstract
Structural designs are progressively more conditioned by uncertainty in a wide
range of fields, and new designs have to meet the requirements of safety and
efficiency. Probabilistic optimization is a powerful tool able to improve and
optimize initial designs into others which are more efficient. In spite of the
continuous growth of computational power, this kind of optimization usually turns
out to be unaffordable, due to the computational cost of the methods involved.
However, parallel computing and surrogate models can overcome this drawback
by reducing drastically the total computational cost of the process. In this paper, a
survey of the performance of several surrogate models combined with reliabilitybased
design optimization is presented. Two examples are selected to show the
behavior of the methods when applied to different models.
Keywords: uncertainty quantification, reliability based design optimization,
surrogate models.
Keywords
