摘　　要：论文提出了复杂产品系统的复杂性就是构成复杂系统的各个学科组成分量之间紧密耦合的非线性相互作用,应该以多学科耦合作用的观点去考虑复杂产品系统的数字样机的开发。基于这个观点,本文以多学科设计优化方法作为复杂产品多学科耦合作用的表现机制,建立多学科产品模型,组织产品数据,表现复杂产品系统的性能和行为特性,从而建立复杂产品系统的早期设计阶段的数字样机。This paper describes the complexity ofthecomplex productsystem is the nonlinearly coupled interaction among the constituents which the complex system is made up of. So we believe the digital prototyping of complex product system should be developed with the standpoint of multidisciplinary coupled interaction. This paper uses the method of multidisciplinary design optimization to express multidisciplinary coupled interaction and establishes the multidisciplinary product model to organize product data. In this way we can exhibit the performances and behavior characteristics of complex product so that we develop a digital prototyping of complex product system for the early design phase.
