Simulation Research on B2B E-commerce Network Based on Local world Core Preferred connection Evolutionary model

摘要:

通过运用复杂网络对B2B电商网络进行建模仿真,发现B2B网络的运行规律,提出减少平台风险的措施。首先分析B2B电商网络的特征和演化动因,提出网络演化的动态规则、局域择优连接规则和自演化规则。接着基于演化规则,在BA模型的基础上,构建更契合于B2B电商网络的局域世界核心择优连接(Local world Core Preferred connection)演化模型。最后,采用NetLogo软件对LCP演化模型进行仿真实验。结果验证B2B电商网络具有无标度性,发现网络具有小世界性；以及网络对随机干扰具有较强的鲁棒性。

Abstract:

By using a complex network to model and simulate the B2B e-commerce network, this paper finds the operation law of the B2B network and proposes measures to reduce the platform risk. Firstly, this paper proposes dynamic rules of network evolution, local preferred connection rules and self-evolution rules based on the characteristics of B2B e-commerce network and the motivation of network evolution. Then it constructs the LCP evolution model based on the evolutionary rules and BA model. The LCP model is more suitable for describing the B2B network operation. Finally,the LCP evolution model is simulated using NetLogo software. The experimental results verify the scale-free property of B2B e-commerce network and find that the network has properties of small world and strong robustness against random interference.
