Complex Network Characteristics and Invulnerability Simulating Analysis of Supply Chain

To study the characteristics of the complex supply chain, a invulnerability analysis method based on the complex network theory is proposed. The topological structure and dynamic characteristics of the complex supply chain network were analyzed. The fact was found that the network is with general characteristics of the complex network, and with the characteristics of small-world network and scale-free network. A simulation experiment was made on the invulnerability of the supply chain network in different attack modes, of which the outcome demonstrates that the supply chain network is not only with the robustness in random failure, but also with the vulnerability to deliberate assault. In addition, the outcome also shows the network reliability depends on the stability of critical nodes (i.e. core enterprises). As a result, it is vital to ensure this kind of enterprise operating normally and efficiently.
