Multidisciplinary design optimization can be described as a methodology for design of systems that involves interaction among several disciplines, and the system performance in more than one discipline can be affected by the designer. The interdisciplinary coupling inherent in designing many engineering systems creates organizational challenges for implementing MDO techniques and also increases computational burden and complexity. These difficulties are particularly evident in the design of aerospace and automotive systems, a process that involves complex analysis, many disciplines, and a large design space. Traditional engineering design optimization methods (e.g. gradient-based design optimization techniques) limit the intercalations among different disciplines and their associated coupled design variables, as well as the design search space; hence lead to sub-optimal design solutions. Fortunately, the advancement of MDO techniques and computing capacity has enabled us to tackle design of complex engineering systems, which involve high fidelity analysis and thousands of couple design variables across several disciplines. Furthermore, the global search methods integrated in these MDO structures can be applied to both continuous and discrete variables; therefore enable the designer to achieve globally optimum design solution. In the first part, a general overview of MDO structures and their applications to complex engineering systems will be presented. In addition, results of a few successful applications of MDO methods to aerospace and automotive structures will be shown. In the second part, the implementation of multidisciplinary approach to engineering design education and innovation at the University of Toronto, Faculty of Applied Science and Engineering, will be introduced. Next, possible participation and collaboration with the University of Toronto – Institute for Multidisciplinary Design and Innovation (UTIMDI0 will be discussed.
