Kendali Optimal Penyebaran Penyakit Influenza H1N1 Tiga Strain dengan Vaksinasi dan Pengobatan

H1N1 influenza is a respiratory tract infection with common symptoms, namely fever, headache, coughing, and sore throat. has several strains known to infect humans, birds, pigs. Some efforts overcome the of virus are vaccination treatment. This Research discusses optimal control in form treatment applied model Influenza disease spread. The method used solve this problem Pontryagin Minimum Principle followed by searching numerical solutions using Runge-Kutta Forward-Backward Sweep method. Numerical simulations were conducted compare spread before after given. Based on simulation result, it was shown that giving susceptible individuals infected three could reduce number .
