1	Variable screening method using statistical sensitivity analysis in RBDO Bae, Sangjune 01 May 2012 (has links) A variable screening method is introduced to reduce the computational cost caused by the curse of dimension of high dimensional problem in RBDO. The screening method considers the output variance of the constraint functions and uses test-of-hypothesis to filter necessary variables. Also, the method is applicable to implicit functions as well as explicit functions. Suitable number of samples to obtain consistent test result is calculated. 3 examples are demonstrated with detailed variable screening procedure and RBDO result. curse of dimension optimization reliability variable screening Mechanical Engineering
