摘要：在人类历史长河中，大规模传染病爆发事件屡见不鲜，这些疫情不仅给全球经济和社会稳定造成了严重冲击，更对人类生命健康构成了巨大威胁。因此，深入研究如何有效控制传染病的传播，已成为当今人类社会面临的重要课题。当前，传染病研究主要集中在病原体鉴定与溯源、流行病学调查与预测、疫苗药物研发以及公共卫生管理等多个方面。本研究深受群体免疫现象启发，特别关注在疫苗资源有限的情况下，如何提升人类社会对传染病的抵御能力。本研究将免疫问题转化为一个优化问题，通过构建以流行病阈值为目标函数、基于节点拓扑势和离散粒子群搜索的群体智能优化免疫策略，旨在实现疫苗接种效益的最大化，显著增强社会网络对传染病的抵抗能力。
In the course of human history, large-scale outbreaks of infectious diseases have been frequent occurrences. These epidemics have not only caused serious impacts on the global economy and social stability but also posed enormous threats to human health and life. Therefore, in-depth research on how to effectively control the spread of infectious diseases has become an important topic facing human society today. Currently, research on infectious diseases mainly focuses on pathogen identification and tracing, epidemiological investigation and prediction, vaccine and drug development, and public health management. This study, inspired by the phenomenon of herd immunity, pays special attention to how to enhance the resistance of human society to infectious diseases in the context of limited vaccine resources. This study transforms the immunity problem into an optimization problem and aims to maximize the effectiveness of vaccination by constructing a Swarm Intelligent Optimization immunization strategy based on the epidemic threshold as the objective function, node topological potential, and discrete particle swarm search. This strategy significantly enhances the resistance of social networks to infectious diseases.
