报告摘要：In this paper, a stochastic SIRS compartmental model is fomulated to investigate the transmission dynamics of infectious diseases. The model incorporates the Beddington-DeAngelis incidence rate and vaccination. For the deterministic model, the basic reproduction number R0 is derived, and the global dynamics is analyzed using the Lyapunov function in terms of R0. The results show that the basic reproduction number completely determines the global dynamics of the deterministic system. For the stochastic model, a new technique is adopted by introducing a Lyapunov exponent λ. Then, the persistence and extinction of infectious diseases are completely determined by λ. If λ < 0, then the disease will die out with probability one, while the epidemic becomes strongly stochastically permanent if λ > 0. To further substantiate our findings, numerical simulations are conducted to validate and extend the theoretical results.
