Evaluation of node importance and invulnerability simulation analysis in complex load- network

In this paper, five evaluation indexes were determined for the evaluation of the node importance of the eco-industrial system, and a comprehensive evaluation method based on the network load was established by introducing the cascade effect model of complex network. Then, by combining the process of industrial production and the operation status of each raw material and production point, the paper analyzes the important sites by using the model principle of cascade effect in the actual production, and designs the optimization scheme on the basis of saving the cost of the enterprise.
