Abstract: To control complex products design change effectively, the influence of important nodes on complex product design changes is revealed in Complex Product Development(CPD) network. To identify important nodes, a weighted CPD network model is constructed, node importance ranking algorithm based on neighborhood coreness within the average path is proposed, in order to solve the non-comprehensive consideration of the process of ranking and the complexity of the algorithm process. The algorithm can consider the factors that affect the nodes importance comprehensively, more scientific, reasonable, simple and efficient to sort the nodes importance. On these basis, the control strategy of complex product design change from the important nodes is expounded. The effectiveness and rationality of the proposed method is verified through empirical study.

Key words: design change, weighted product development network, nodes importance, neighborhood coreness, control strategy

摘要: 为了有效控制复杂产品设计变更,在复杂产品开发(Complex Product Development,CPD)网络中揭示了重要节点对复杂产品设计变更的影响。为了识别重要节点,构建出加权CPD网络模型,提出基于平均路径以内邻居核数的节点重要性排序算法,以解决排序过程中考虑因素的不全面性及算法过程的复杂性。该算法能够全面考虑影响节点重要性的因素,更加科学、合理、简单、高效地对节点重要性进行排序。并在此基础上阐述了从重要节点出发的复杂产品设计变更控制策略。通过实证研究,验证了所提方法的有效性和合理性。
