Research on Evolution of Quality Chain Network Model Based on Multi-Attribute Weighting of Complex Network

Using the linear optimal connection mechanism of complex network model, a multi-attribute weighted quality chain network model construction method is proposed. Firstly, the enterprise node in the quality chain is defined to have its self attributes of quality elements and node business relevance. Secondly, the degree and the intermediate number are combined to comprehensively consider the local and global characteristics of the network to express the network attributes of the node, and the multi-attribute weighted quality chain network edge connection strategy algorithm is designed under the combination with the node's own attribute weighting. Finally, the simulation results show that the quality chain network model established by this strategy meets the scale-free characteristics and has higher network efficiency and stronger network invulnerability which proves that the newly established model is reasonable.
