这篇论文研究了基于级联失效的应急产业供需网韧性，旨在为提升应急响应效率提供理论依据和实践指导。作者构建了一个应急产业供需网的级联失效模型，并通过模拟不同强度的随机攻击，分析节点失效对网络稳定性的影响，量化了网络的抵抗、吸收、缓冲与恢复能力等韧性指标。研究发现，网络韧性与其灾后恢复效率直接相关，冗余设计和关键节点保护对提升网络韧性至关重要。This paper studies the resilience of the emergency industry supply-demand network based on cascading failure, aiming to provide theoretical foundations and practical guidance for improving emergency response efficiency. The author constructs a cascading failure model for the emergency industry supply-demand network and simulates random attacks of varying intensities to analyze the impact of node failures on network stability. The resilience indicators, including resistance, absorption, buffering, and recovery capabilities, are quantified. The study finds that network resilience is directly related to post-disaster recovery efficiency, and that redundant design and protection of key nodes are critical to enhancing network resilience.
