Abstract

How to control the epidemics most quickly when SARS outbreaks, an optimal concept of control measures for SARS epidemics spread is proposed, this is bang-bang switching control based on the subsystem of the compartmental model. The subsystem includes only two variables: exposed class E(t) and infectious class I(t) in free block of a community, but they are the main source of SARS epidemics spread. Mathematically, we proved that a maximum quarantine/isolation measures for them will reduce SARS epidemics to minimum extent in minimum time according to Pontryagin´s minimum principle. Finally, the numerical simulations are given, the results are satisfied
