摘　　要：针对现有设计变更模型存在冗余关系而影响设计变更效率和质量的问题,提出了一种基于商空间理论的设计变更模型构建及优化方法。基于商空间理论构建了多粒度下产品系统功能关系模型。通过功构映射建立了产品系统设计变更模型,采用合并策略建立了产品系统最小设计变更模型。根据变更传播强度确定设计变更模型优化目标,建立了一种基于改进蚁群优化算法的变更传播路径优化方法,建立了基于最小设计变更模型的变更路径搜索过程。以烧结炉的设计变更为例,验证了该方法的可行性与有效性。Aiming at the issue of redundant relationships in the existing design change model that affect the efficiency and quality of design change,a design change model construction and optimization method based on quotient space theory is proposed.A multi-granularity product system functional relationship model is constructed using quotient space theory.The product system design change model is established through function-structure mapping,and the minimum design change model of product system is established by using the merge strategy.The optimization objective of the design change model is determined based on change propagation intensity,and a design change propagation path optimization method is presented,utilizing an improved ant colony optimization algorithm,and the process of change path search is established based on the minimal design change model.The feasibility and effectiveness of the method are demonstrated through a case study involving design change in a sintering furnace.
