MULTIDISCIPLINARY ROBUST
OPTIMIZATION DESIGN*
Abstract:
Because uncertainty factors inevitably exist under
multidisciplinary design environment, a hierarchical
multidisciplinary robust optimization design based on response
surface is proposed. The method constructs optimization model of
subsystem level and system level to coordinate the coupling
among subsystems, and also the response surface based on the
artificial neural network is introduced to provide information
for system level optimization tool to maintain the independence
of subsystems, i.e. to realize multidisciplinary parallel
design. The application case of electrical packaging demonstrates that reasonable robust optimum solution can be yielded and it is a potential and efficient multidisciplinary robust optimization approach.
Key words:
