摘要：针对产品通用平台的多域统一辨识问题,从产品结构、功能和用户需求的并行角度对产品通用平台辨识进行了研究。分别构建了产品结构域无向图模型、功能域有向图模型和需求域向量表模型。在此基础上,建立了产品通用平台辨识多约束耦合空间模型和对应的多约束耦合矩阵。把产品通用平台跨域统一辨识问题,转变为求多约束耦合空间一系列当量距离的问题。对当量距离进行综合排序后,根据企业生产能力和市场细分情况确定点的范围,形成优化的产品通用平台集合,使对产品通用平台辨识的模糊求解转变为定量化求解。最后,以轮式装载机为例,验证了各模型在产品通用平台辨识应用中的有效性。

摘要：Green design and manufacturing is a proactive approach to minimize wastes during a product’s design stage, thus preventing future environmental impacts. Current modular design method mainly focuses on product functional and manufacturing issues. In this paper, a theoretical scheme of multi-objective modularity analysis for discrete electromechanical product design was proposed. Product physical architecture was represented by a fuzzy graph, where fuzzy relationships contain environmental objectives and influence module formulation. Finally the optimal product modules combining all objectives can be searched by clustering algorithm.
