|Myltidisciplinary design optimization can yield optimal design considering all the disciplinary requirements concurrently. A method to implement the collaborative optimization approachm one of the MDO methodologiesm is developed using a precompiler "ezPreCompiler", a design optimization libray "EzOptimizer", and a common objiect request broker architecture in distribued computing environment. The CO approach is applied to a mathematical example to show its applicability and equivalence to standard optimization formulation, In a realistic engineering proble such as optimal design of a two member hub fram, optimal design of a speed reducer and initial design of a bulk carrier, the CO yields better results than the SO. Furthermore, the CO aloows the distributed processing using the CORBA, which leads to reduction of overall computation time.
