Abstract:

Multidisciplinary Design Optlmization（MDO） has made great progress based on traditional optimization. It is a method for complicated systems, which   integrates the design methods, the traditional knowledge of machine design and design process, and the modern information technology. The goal of MDO is   to improve the products, shorten the cycle of design and reduce the cost. We compare the MDO method with traditional optimization methods in this paper ,and prove that MI）O is feasible and efficient by an example.

Key words: multidisciplinary design optimization;traditional design optimization;information technology
