突发灾害下考虑地铁网络脆弱性的应急资源调度方法
Emergency resource dispatch method considering subway network vulnerability under sudden disasters
摘要
Abstract
To allocate emergency resources rationally and efficiently,considering both transportation costs and time,and ensuring rapid and effective response during the initial stages of disasters,this study used the urban rail transit network of Shenzhen as a case study.Addressing the vulnerability of transit networks to disruptions caused by disasters,a method based on collective influence was employed to identify critical nodes in the Shenzhen urban rail transit network and prioritize them using weighting coefficients in an optimization model.A multi-objective emergency resource allocation optimization model was established to minimize emergency dispatch time,costs,and penalties.Genetic algorithms were employed to solve the model,establishing effective emergency resource allocation strategies aimed at maximizing response efficiency and ensuring supply of high-priority resources.Comparing and validating the urban rail transit network examples of Shenzhen and Shanghai,the results show that the proposed model can effectively balance the cost and efficiency of emergency resource allocation.It can particularly ensure prioritized supply to critical nodes under inadequate resource conditions.This significantly reduces the risk of the urban rail transportation network being affected by the impact of emergencies,and effectively guarantees the stable operation of the overall network.The study can identify crucial but often overlooked weak-link stations critical to the network's overall stability,offering insights for emergency resource allocation in urban rail transit systems during crises.This research can contribute to enhancing overall urban resilience and efficiency in responding to emergencies.关键词
