Multidisciplinary Collaborative Design Optimization Modeling Method of Complex Product

Complex products are often composed by a number of subsystems which coupled by some complicated way. In order to meet the need of multidisciplinary collaborative design optimization, the multidisciplinary collaborative optimization model of complex products was established based on distributed hierarchical system, including system-level optimization model, optimization model subsystem and subsystem analysis model. To solve the problem under uncertainty, complex products multidisciplinary collaborative design optimization modeling under uncertainty was concluded based on the introduction of uncertainty analysis to determine the system of objective function and the corresponding relationship between the uncertain variables. Finally, multidisciplinary collaborative optimization modeling process of complex product was provided.
