Study on robust collaborative optimization with mixed-discrete variables of complex products

In this paper, through the process of designing complex products, by combining a model of collaborative optimization with robust design, we built the model of robust collaborative optimization with mixed-discrete variables. And the model was validated by an actual engineering case, which was a typical Multidisciplinary design optimization (MDO) case. In the meantime, we analyzed the result and compared it with the result got from the collaborative optimization model with mixed-discrete variables to verify the effect by robust design.
