摘要
研究了SIR模型在连续接种、脉冲接种、治疗等不同策略下平衡点的稳定性,获得了疾病灭绝的阈值条件.通过比较各种控制策略的有效性,说明接种比治疗更能有效控制疾病,同时应用两种控制策略比单独应用一种更有效.
The stability of the equilibrium on SIR epidemic model under continues vaccination,pulse vaccination and treatment are studied,and the threshold conditions of disease dying out are obtained.By comparing the effectiveness under different control strategies,the results that vaccination is more effective than treatment,and using two strategies concurrently is superior to only one for eradicating the disease.
