基于复杂网络的供应链建模及仿真研究

Supply Chain Modeling and Simulation Research Based on Complex Network

摘要:

本文基于BA无标度模型构造了一个虚拟的供应链网络,并对其进行仿真,分析了其度分布,发现该虚拟供应链网络的度分布服从幂律分布,依然是一个无标度网络,还分析了该虚拟供应链网络的平均路径长度和聚类系数,发现其平均路径长度很短,聚类系数很高,同时也是一个小世界网络。并且基于度分布、平均路径长度和聚类系数提出了改进供应链的建设、提高其稳定性和运作效率的建议和途径。

Abstract:

In this paper, We propose a virtual supply chain network based on BA scale-free model and simulate it. Analyze degree distribution and find it obey power-law distribution, so the virtual supply chain network is still a scale-free network. We also analyze average path length and cluster coefficient, find average path length is very short and cluster coefficient is very large, so it is also a small-word network. Then put forward suggestions and ways about how to construct supply chain network better and improve its stability and operation efficiency based on analyses above.
