State constraints optimal control problems applied to ebola epidemic model
Optimal control is a powerful tool that provide useful information in order to combat the progression of a disease by testing and comparing different vaccination strategies. In this talk, I will emphasize on vaccination of susceptibles individuals as control function, as well as on the number of available vaccines as state contraints to a Ebola model. In this direction, state constraints on the number of available vaccines can be studied after considering an appropriate cost functional to 8-dimensional nonlinear differential equations modeling the dynamics transmission of Ebola disease. Further, we analyze an optimal control problem where there is limitation on the supply of vaccines either in a fixed period of time or at each instant of time. The optimal control problem is solved analytically by maximum principle of Pontryagin type. Finally, a number of numerical simulations is performed in order to validate the analytical result.
