Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Due to the unpredictability of Covid-19 and the complexity of community transmission, the existing theories and methods of system resilience assessment can not meet the needs of city epidemic prevention complex network resilience assessment. Therefore, this paper constructs a epidemic transmission complex network and studies the epidemic transmission model on the network---the Improved SEIR. And the paper predicts the development of the epidemic, point out the vulnerability of the network and the vulnerability of epidemic prevention. Then, according to the network structure of epidemic prevention and the results of SEIR model, the new theory and method of epidemic prevention resilience assessment in City A were constructed, and the resilience assessment of complex epidemic prevention network was divided into two dimensions network structure resilience and urban function resilience. The new methods for the city epidemic prevention complex network resilience assessment are simulationed through measured data. The results show that when the epidemic comes, improving the resilience of urban epidemic prevention functions has a better effect on epidemic prevention and control. The paper integrates improved SEIR models with urban anti-epidemic measures, providing a new approach to resilience assessment of complex systems.
