城市防疫医疗救援网络的抗毁性与鲁棒性

Anti-destructive and Robustness of Urban Epidemic Prevention Medical Rescue Network

为研究城市防疫医疗救援系统空间布局的合理性和防灾韧性,采用复杂网络技术构建了某城市防疫医疗救援网络模型,对其网络拓扑结构和网络特征基本参数进行分析,研究不同攻击模型下以边和点连通度为度量指标的结构抗毁性能力;通过设定不同的网络冗余与网络负荷,研究网络针对确定性攻击与随机性攻击的鲁棒性特征。研究结果可为城市防疫医疗救援系统的空间优化布局和核心场所强化建设提供理论支撑。

To study the rationality and disaster prevention resilience of the spatial layout of urban epidemic prevention medical rescue system,a network model of a city's medical epidemic prevention and rescue was constructed by using complex network technology,analyzing its network topology and basic parameters of network characteristics,and studying the invulnerability of structures with edge and point connectivity as metrics under different attack models.By setting different network redundancy and network loads,the robustness of the network against deterministic attacks and random attacks were studied.The research result can provide theoretical support for the spatial optimization layout of urban epidemic prevention medical rescue system and the strengthening construction of core sites.
