MDO Combine analysis in several disciplines to optimise through a formal mathematical process.

MDO - Role of CASDE Facilitate creation of –Infrastructure for MDO –Awareness about MDO amongst the industry Studies –Optimization and software aspects of MDO –Issues of integrating higher fidelity levels of analysis formal optimization early in the design phase

MDO - Activities Awareness Creation Formation of SIG-MDO SIG-MDO Workshop-cum-Meeting – August (Continued & active participation by ADA, DRDL, CABS, GTRE) Professional Course on MDO – January Professor Prabhat Hajela, RPI, USA. Dr. Gary Vanderplaats, GENESIS fame. Upcoming events SIG-MDO Meeting (March 2002) International Conference on MDO (2003)

MDO - Studies Comparative study of various MDO architectures Response surface approximations; Gradient Evaluation, Optmisers,.. MDO studies –Varying levels of fidelity of analysis –Simultaneous aerodynamic and structural optimization without/with aeroelasticity –Wing optimization.; MLC; –AEW System Optimisation
