Sometimes the level of structural complexity exceeds our ability to make design changes, especially in aerospace engineering, where a single design is performed by different teams, each one focusing on a different subject. It goes without saying that the final target of the different teams is the same, for example minimizing the structural weight. Multidisciplinary design optimization (MDO) is exactly the field of engineering that uses optimization methods to solve design problems incorporating a number of disciplines. Design optimization is the process of generating improved design through the use of different algorithms. This process is performed by an optimizer, which, in order to achieve the best solution, uses the design sensitivity coefficients.
