基于SI1I2R模型的高校突发事件网络谣言传播动力学研究OA

Using the ideas and methods of infectious disease dynamics modeling to simulate the spread of online rumors in college emergencies can provide reference for relevant departments of schools to effectively control the spread of rumors,so as to more effectively manage and control the spread of rumors.Firstly,the university population is divided into four categories:susceptible(S),rumor spreader(I1),truth denier(I2)and immune(R),and the SI1I2R network rumor model is established;Secondly,the next gener-ation matrix method is used to calculate the basic reproduction number,and the existence and stability of zero rumor and truth transmission equilibrium points,two kinds of nontrivial transmission equilibrium points and positive equilibrium points are theoretically analyzed;Finally,matlab software is used to carry out numerical simulation to further verify the dynamic behavior of online rumor spread.The research results show that schools should strengthen students'network security education,improve students'in-formation recognition ability,and help students not believe rumors or spread rumors before the incident;When an incident occurs,the school should timely release authoritative information,stabilize students'emotions,cut off the source of rumors,ensure that students know the truth,and further curb the spread of rumors.
