| Outline of Final Research Achievements |
In this research, we have established the stochastic vaccination strategies for infectious diseases. First, taking account of random fluctuations in the infection or the recovery rates caused by the environmental change, we have proposed the stochastic infectious models using the stochastic differential equation. Secondly, we have estabilisheded the stochastic optimal vaccination strategies using the stochastic maximum principle and the four-step scheme. finally, the efficiency of the proposed optimal vaccination strategy is verified by the numerical simulations.
