摘要
为探寻舆情传播规律并找到相应对策,借鉴流行病学仓室建模的思想,建立了舆情传播的微分方程模型,基于舆情传播模型的分析,得出了对于正面舆情,应控制模型参数使系统趋于正的平衡点,使传播者不断增加;对于负面舆情,应控制模型参数使系统趋于负的平衡点,实现传播者不断减小的舆情控制策略.
In order to explore the law of public opinion spread and find the countermeasures,based on infectious disease compartmental model, a differential equation model of Public opinion spread is built, by analyzing, public opinion control strategy is obtained, for the positive public opinion, should make the system move towards the positive balance point to make infectors increase by controlling the parameters of the system; and for the negative public opinion, should make the system move towards the negative balance point to make the infectors decreases by controlling the parameters of the system.
