Optimal Control of Vaccination for Dengue Fever in SIR Model

According to data from The Indonesian ministry of health, many individuals suffere dengue fever until may 2023 in Indonesia. To reduce its cases, this article, a single control strategy vaccination for infected human by has been proposed. obtain the optimal control, SIR model modificated with and new objective function made before Pontryagin minimum principle is used article. differential equation function, we Hamiltonian equation. Then, it, state equation, costate stationary condition so obtained vaccination. In end did numerical simulation using sweep forward-backward method. Through simulation, find that succeed also increase recovery desease. Futhermore, should be implemented not only mathematical but into real life decrease case.
