DOI: 10.1080/0305215x.2019.1702978
Abstract: There are many uncertain factors in aerospace structures, such as variations in manufacturing tolerance, material properties and environmental aspects. Although conventional robust design optimization (RDO) can effectively take into account these uncertainties under the specified… read more here.
