摘要


研究了信息和疾病在重叠网络上的传播过程. 疾病可通过物理接触网络传播,信息可以通过物理接触与虚拟接触传播. 利用马尔可夫链方法,建立了重叠网络上疾病与信息传播的模型,并计算出了其传播阈值. 通过数值模拟可知,信息的传播抑制了疾病的传播,并有效降低了疾病传播的最终规模,但对疾病传播阈值的影响不是很大; 此外,疾病的传播有效地促进了信息的传播. This paper studies the spreading process of information and disease in the overlay network. The disease can transmit through physical contact. However, information can spread through not only physical contact but also virtual contact. By using the Markov chain method, it establishes a model of disease propagation and information transmission, and obtains the threshold value. The numerical simulation shows that the information transmission can help prevent the disease propagation and effectively reduce the final scale of the disease propagation. However it has little impact on the threshold of the disease. In addition, the disease propagation promotes the information transmission.
