生态视角的复杂产品协同设计网络稳定性研究

Stability of Complex Product Collaborative Design Network from Ecological Perspective

针对复杂产品群智协同设计网络中用户群体结构对其稳定性的影响机制不明确的问题,提出了新的网络稳定性分析方法。基于生态位理论分析了网络中的生态角色,定义了个体生态位表征模型,采用移除网络节点方式进行了实证研究。研究发现,生态位宽度大的多面手和普通设计者及具有较小生态位宽度的多面手是影响网络稳定性的关键角色。研究成果能够为复杂产品群智协同设计网络的精准调控提供参考。

Aiming at the problem that the influence mechanism of user group structure on the stability of complex product group intelligent collaborative design network is not clear,a new stability analysis method of complex product group intelligent collaborative design network is proposed.Based on niche theory,this paper analyzes the ecological role in the intelligent collaborative design network of complex product groups,defines the individual niche representation model,and makes an empirical study by removing network nodes.It is found that generalists with large niche width,ordinary designers and generalists with small niche width are the key roles affecting the stability of the network.The research results provides a reference for the precise regulation of complex product group intelligent collaborative design network.
