摘要: 为更好地快速响应市场的多样化需求,引入面向可适应性的产品平台结构概念。根据稳健设计与可适应设计在提升产品适应外部环境变化的能力、考虑设计变更及以低成本获得高质量产品方面的一致性,提出了面向可适应性的稳健性产品平台规划方法,在产品平台规划初期就开始考虑产品的稳健性,并使设计具有可适应性,以避免后期出现大的返工。以公理设计理论为指导,通过“Zigzagging”映射,依照功能需求分析及三种类型的划分,合理提炼特征设计参数,建立产品平台的功能要求和设计参数矩阵。将灰色系统理论应用到产品平台的稳健设计中,结合试验设计与关联度方差分析,合理识别平台参数和变型参数。然后分两阶段进行稳健优化,确定产品族基体产品和每个变型产品的设计参数的最佳设计方案。通过卷筒组产品族的规划实例,说明了该方法的可行性和实用性。

Abstract: To quickly respond to customers’ individual needs and markets demand diversification, the concept of product platform architecture for adaptability is defined, and an adaptability-oriented planning method for robust product platform is presented. Due to the conceptual consistency on promoting the adaptability to environmental change, considering design changes and improving product quality with low costs, it is therefore natural to unify robust design and adaptable design. In initial phase of product platform plan, the robustness and design adaptability should be considered to avoid rework. The axiomatic design theory is utilized as framework to “zigzaging” mapping between functional requirements and design parameters. According to the analysis on functional requirements, the functional requirements are divided into basic functional requirements, expectable functional requirements and adjunctive functional requirements. The design characteristic parameters are extracted reasonably and the functional requirements matrix and design parameters matrix are established respectively. The grey system theory is made use into robust design of product platform, the platform parameters and variety parameters are identified through the experimental design and analysis of variance for the grey relational grade. Then a two –stage method for robust optimization problem of product family is proposed to determine the best design scenario for product platform and product variety. Finally, an example of flexible product configuration for drum is used to demonstrate the feasibility and practical value of the proposed method.
