摘　　要：为综合考虑产品造型设计多阶段决策信息,引入复杂网络理论,提出了产品造型设计多阶段网络耦合决策流程。对产品造型设计多阶段决策关系进行了耦合关联建模,基于对决策者评分的一致性分析确定设计决策网络的邻接矩阵,依据网络凝聚度变化获得决策者权重,以设计决策网络凝聚度的稳定性和决策者意见一致性确定决策轮次,构建规划函数计算产品造型设计决策各阶段权重,通过线性耦合实现多阶段决策信息集结。以数控磨床造型设计决策为例验证了方法的有效性,结果表明所提方法能够实现产品造型设计多阶段决策信息的集结,提高设计决策的全局性和科学性。To comprehensively consider multi-stage decision-making information of product styling design, the complex network theory was introduced and a multi-stage network coupling decision-making process of product styling design was proposed. The relationship of multi-stage decision-making information of product styling design was modeled with coupled association. Based on the consistency analysis of decision-makers’ scores, the adjacency matrix of design decision-making network was identified. The decision-makers’ weights were obtained by calculating changes in network cohesion. Through analyzing the stability of decision-making network cohesion and the consistency of decision-makers’ opinions, the number of decision-making rounds was determined. To compute the weights of each stage in the decision-making process of product styling design, a programming function was constructed, and the aggregation of multi-stage decision-making information was realized through linear coupling. Taking the decision-making of numerical control grinder styling design as an example, the effectiveness of the method was verified. Results show that the proposed method can help realize the aggregation of multi-stage decision-making information of product styling design and improve the quality of design decision-making in an overall and scientific way.
