基于复杂网络理论,用边权重表示知识转移强度,且在加权网络的基础上,提出了敏捷供应链知识服务网络的演化机制。通过对强度分布、权重分布、度分布和聚类系数等4个网络特征量的定性分析,提出了知识服务网络的演化趋势,并进行仿真实验,验证了敏捷供应链知识服务网络的无标度特性,揭示了其演化过程,且在鲁棒性方面较无标度网络表现出优越性。在网络内部演化过程中不仅考虑了边的增加,还考虑到知识转移造成的边权重的变化,更全面地刻画了敏捷供应链知识服务网络的生长演化过程。
Based on the complex network theory, with the edge weights being knowledge transfer intensity, we propose and analyze the evolution mechanism of knowledge service network in the agile supply chain using the weighted network. The four network characteristics-strength distribution, weight distribution, degree distribution and clustering coefficient-are qualitatively analyzed to develop the evolution trend of knowledge service network. The simulation experiment verifies that knowledge service network in the agile supply chain is a scale-free network. It reveals the evolution process of knowledge service network in the agile supply chain, which shows knowledge service network in the agile supply chain has better robustness than a scale-free network. During the internal network evolution process, this paper takes not only the increase of edges into account, but also considers the variation of edge weights due to knowledge transfer, which describes the growth and evolution process of the knowledge service network in agile supply chain more thoroughly.
