【摘要】:研究三種意識對疾病傳播的影響,建立了無標度網(wǎng)絡上的SIS模型,并得到了該模型無病平衡點的穩(wěn)定性及傳播閾值。結果表明局部意識和接觸意識可以提高傳播率的閾值,全部意識對無病平衡點的穩(wěn)定性及傳播閾值沒有影響。最后利用數(shù)值模擬驗證了理論結果。
[Abstract]:The influence of three kinds of consciousness on the spread of disease is studied. The SIS model on scale-free networks is established and the stability and transmission threshold of the disease-free equilibrium of the model are obtained. The results show that local consciousness and contact consciousness can improve the threshold of transmission rate, and all consciousness has no effect on the stability and transmission threshold of disease-free equilibrium. Finally, the theoretical results are verified by numerical simulation.
