Disease propagation dynamics method based on dynamic isolation

The invention belongs to the research field of complex networks and propagation dynamics, and particularly relates to a disease propagation dynamics method based on dynamic isolation, which comprises the following steps: collecting social relation data of crowds, preprocessing the social relation data, and constructing the preprocessed data into a complex network; classifying nodes in the constructed network and calculating importance indexes of the nodes in the network, thereby laying a foundation for construction of a subsequent propagation dynamics model and calculation of dynamic isolation indexes; comprehensively calculating the calculated node importance index to obtain an improved dynamic isolation measure index; introducing the dynamic isolation index into a propagation dynamics model to obtain a propagation dynamics model based on dynamic isolation, namely an SEIQR model; the propagation dynamics model is propagated on a complex network, the propagation condition is compared with the condition that i
