面向多域协同的复杂产品再设计模块主从识别

为了在多主体参与、多需求共存条件下有效识别复杂产品再设计中各模块的主从关系，提升再设计效能，构建包括认知域、需求域及模块域的多域协同评价方法. 基于认知域中不同认知主体的情感需求及物理需求，完成设计需求域的建立. 结合模糊评价及相对偏好分析，获取需求域映射的各模块域间映射重要度. 考虑模块间的关联关系，提出模糊设计结构矩阵理论与DEMATEL结合，获取各模块的域内相关重要度. 运用合作博弈思维建立结合域间映射重要度及域内相关重要度的综合评价模型，识别各模块的主从关系. 相较于从单一角度进行模块重要度分析模式，所提方法的评价结果更为客观、全面、准确. 以CKA6180数控机床为例，验证多域协同的模块主从关系评价方法的有效性与可行性.

Leader-follower identification of complex product redesign modules for multi-domain collaboration

A multi-domain collaborative evaluation method including cognitive domain, demand domain and module domain was constructed, in order to effectively identify the master-slave relationship of each module in complex product redesign under the condition of multi-agent participation and multi-demand coexistence, and to improve the efficiency of redesign. The design requirements domain was established based on the emotional and physical needs of different cognitive subjects in the cognitive domain. Combined with the fuzzy evaluation and the relative preference analysis, the inter-domain mapping importance of each module for the requirement domain mapping was obtained. Considered the connection relationship among modules, a fuzzy design structure matrix combined with DEMATEL was proposed to obtain the intra-domain correlation importance of each module. Using the cooperative game method, a comprehensive evaluation model was established, which combined the inter-domain mapping importance and the intra-domain correlation importance to identify the master-slave relationship of each module. Compared with the module importance analysis mode from a single perspective, the method obtained more objective, comprehensive and accurate evaluation results. Taking the CKA6180 CNC machine tool as an example, the effectiveness and feasibility of the multi-domain collaborative evaluation method were verified.
