Multi-objective RBDO in UQLab

UQ with UQLab Community Q&A and How To
1

Dear UQLab,

Hope you find this question informative;
Would you mind please let me know if UQLab can support different quantities of interest (QoIs) in the cost function of RBDO to build a multi-objective RBDO problem? For instance, I want to minimize both Drift and Weight of a structure simultaneously via RBDO.
Last but not least, I am most grateful for your kind suggestions/recommendations.

Kind regards,
Ali

As always, I will be honored if I can benefit from the suggestions/recommendations of Dr. @moustapha and other RSUQ members.

Best regards,
Ali

Dear @ali
As of now, this is not supported in UQLab. The only way you could solve this iwithin UQLab is to create an aggregate cost function by combining the ones you have through weighted sums.

Best,
Moustapha
