摘　　要：目的复杂产品在工程装备、航空航天等我国优先发展的战略领域中扮演着不可替代的重要角色,在其结构设计过程中普遍存在着各种不确定性,导致产品结构性能很难实现最优,甚至出现重大故障。方法针对复杂产品设计过程中的多粒度模糊不确定、随机不确定、不完备区间不确定和高维混合不确定等特点,将不确定性理论与产品结构设计过程相结合,系统地构建了不确定视角下产品结构性能优化设计理论体系,提出了多粒度模糊不确定下产品质量特性精准提取、随机不确定下产品功能结构模块化求解、不完备区间不确定下产品结构方案多属性决策、高维混合不确定下产品关键结构可靠性优化等关键技术,并指出了产品结构性能优化设计的未来发展方向。结论此设计理论能够充分适应和利用产品设计过程的多种不确定信息,为在结构设计环节切实提升产品性能提供了有力参考。Complex products play an irreplaceable role in the priority strategic fields of our country,such as engine­ering equipment,aerospace and so on.There are various uncertainties in the structural design process for complex product,which make it difficult to achieve optimal performance,or even major failures occur.Focusing on the characteristics of multi-granularity fuzzy uncertainty,random uncertainty,incomplete interval uncertainty and high-dimensional heterogeneous uncertainties in the structural design process of complex product,the uncertainty theory and the product structural design process are integrated,and the theoretical system of product structural performance optimization design is established systematically from the perspective of uncertainty.The key technologies of accurate extraction for product quality characteristic under multi-granularity fuzzy uncertainty,modular solution for product function structure under random uncertainty,modular solution for function structure under random uncertainty,multi-attribute decision-making for product structure scheme under incomplete interval uncertainty,and reliability optimization for key structure under heterogeneous high-dimensional uncertainties are proposed,and the future development directions of product structural performance optimization design are also pointed out,providing a reference for improving product performance in the structural design process.
