通过研究政府辟谣策略对谣言传播过程的影响,建立了非均匀网络中考虑辟谣机制的谣言传播模型,并得到了对应的平均场方程。通过稳定性分析得到了与辟谣机制强度以及网络结构有关的谣言传播阈值。仿真结果表明:无论是在均匀网络中还是在BA无标度网络中,传谣者最大影响力随辟谣率的增大而减小,并且对无知者进行辟谣可以有效降低谣言传播的最大影响力,对传谣者进行辟谣可以有效地降低谣言传播中移出者最终数。
By studying the influence of the government’s rumor strategy on the rumor transmission process, a rumor propagation model considering the rumor mechanism in the non-uniform network was established and the corresponding mean field equation was obtained. Through the stability analysis, the threshold of rumor transmission related to the strength of rumor and network structure is obtained. The simulation results show that the maximum influence of rumor folk diminishes with the increasing rumor rate both in homogeneous network and in BA scale-free network, and denying the ignorant person can effectively reduce the maximum influence of rumor transmission , Rumor folk rumor can effectively reduce the final number of rumors spread in the dissemination.
