MDO
Combine analysis in several disciplines to optimise
through a formal mathematical process.
www.casde.iitb.ac.in/MDO
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 2000. (Continued & active participation by ADA, DRDL, CABS, GTRE)
• Professional Course on MDO – January 2001. 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
1. System I/O
2. Decide Subsystems
3. Decide subsystem I/O and interactions
… Down to design tasks

Framework for MDO
• Requirements capture– Through literature
– Study of existing frameworks
(academic pricing for 1 year 4 lakhs to 12 lakhs)
• Sharing models for integration– Make models available
– Retain autonomy
