摘　　要：复杂产品往往由多个子系统通过复杂的耦合方式组成。针对复杂产品多学科协同设计优化的需求,将复杂产品分解成为分布式层次型系统,建立复杂产品多学科协同优化模型,包括了系统级优化模型、子系统优化模型和子系统分析模型。为解决不确定条件下的复杂产品优化建模问题,在确定性条件下建模方法的基础上引进不确定分析,得到系统目标函数与不确定变量之间的对应关系,建立不确定条件下的复杂产品多学科协同优化模型。最后,给出了复杂产品多学科协同优化建模过程。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.
