基于信息网络的复杂产品系统研发风险识别

Risk Identification of Complex Product System R&D Based on Information Network

通过研发过程的特征,将复杂产品系统的研发过程映射为合作主体之间的信息处理过程,构建信息网络模型。基于信息网络中的信息节点交互和信息节点质量评估,构建了复杂产品研发过程风险识别模型。最后通过数值仿真,求解不同信息网络结构所对应的信息网络风险阈值。提出的风险识别方法能够从信息视角表征研发过程的实质,缩小了风险识别的粒度,提升了风险识别的动态敏锐度。

Through the characteristics of R&D process,the R&D process of complex product system is mapped to the infor⁃mation processing process between cooperative subjects,and the information network model is constructed.Based on the informa⁃tion node interaction and information node quality evaluation in information network,a risk identification model of complex product R&D process is constructed.Finally,through numerical simulation,the information network risk threshold corresponding to differ⁃ent information network structures is solved.The proposed risk identification method can characterize the essence of the R&D pro⁃cess from the perspective of information,reduce the granularity of risk identification and improve the dynamic sensitivity of risk identification.
