【摘要】 现今的供应链是一种动态网状结构,因此借助复杂网络理论可以较好地对其进行研究。本文探讨了供应链网络的形成过程及相应的拓扑结构,然后在此基础上,建立了包含以节点泊松进入和随机退出为增长机制的择优连接模型,并用连续化方法分析了该模型的度分布,最后通过数值模拟进行验证。更多还原

【Abstract】 At present,supply chain constitute a dynamical network and then can be well studied based on the complex network theory.The paper analyzes the forming process and topology structure of the supply chain network,and then on this basis proposes a preferential attachment model with Poisson addition of new nodes and random deletion of existing nodes.At last,we discussed the degree distribution of this model by continuum theory and simulation.更多还原
