A rule of the target cascade optimization based on design structure matrix

Accordingtoanalytical Target Cascading is a multi-level decomposition and coordination of the centralized multidisciplinary optimization method,and structure design matrix isparticularly effective the coupling relationship of complex decompositionbetween the system.Therefore,With the combination of the method to come up with a kind of target cascade optimization rules based on design structure matrix,which reduces the information interactionand the number of iterationat first through the design structure matrix.Finally,proving the method which can quickly get an optimization designby the gear reducer optimization example.
