Abstract EN
On the basis of nonlinear dynamic model, we research the propagation of rumors after emergencies, describe the impact of media coverage and emergency strategies by government on the transmission dynamics of information, and then obtain the basic reproduction number of rumor spreading.
In order to overcome the limit of traditional methods of the static decision problem, the dynamic optimal control model for the rumor spreading is proposed based on the theorem of the optimal control.
An optimal objective based on the maximum social utility is established and the optimal solution is acquired by using the Pontryagin Maximum Principle.
Finally, numerical simulations show that the dynamic optimal control method has obvious superiority in modeling compared with the method without control.
By means of the dynamic optimal control of media coverage and emergency strategies for government, the final rumor scale and the peak of spreaders can be effectively reduced.
