Abstract
This research paper investigates the SIZR model related to Zombie infection outbreaks according to a time-dependent infection rate. The proposed model is extended to the fractional order using different fractional derivative operators. The solution of the proposed model by numerical schemes, is briefed. Graphical representations provide us with a better understanding of this mathematical model. Lastly, as observed in movies, we conclude that Zombie infections can generate the destruction and collapse of human development and it is of paramount importance to deal with Zombies as early as possible in order to avoid putting our civilization under threatening and destructive circumstances.
