铁路突发事件应急资源调配的优化与决策

优化铁路应急救援资源的调配是降低突发事件人员伤亡、减少财产损失的重要途径。基于应急资源调配的特点及要求,建立应急资源调配时间最短的单目标模型,以及调配时间最短,且应急出救点最少的双目标模型;并运用分层序列法进行求解。研究表明,双目标模型优化可以减少应急出救点、节约救援成本。利用Matlab软件设计应急资源优化调配的决策程序,实现资源调配决策的快速化、科学化;并以南昌铁路局为例进行实证分析。研究成果为铁路突发事件的科学应急救援,减少事故救援时间和成本提供参考。

Optimization and Decision-making of Emergency Resource Dispatch in Railway Incidents

The optimize dispatch of railway emergency resource is an important way to limit casualties and reduce property losses. Based on the characteristics and requirements of emergency resources dispatch, the paper established two optimal models, the single objective model is aiming at minimizing the time of emergency resource dispatch, the double objective model is for the sake of minimizing the time of emergency resource dispatch and the number of emergency rescue base, and the paper used Voting Analytic Hierarchy Process (VAHP) of operations research to solve the model. The study shows that the double subjective model can reduce the number of emergency rescue base and the cost of rescue. By using Matlab software, the decision-making process of emergency resource optimize dispatch was designed, making the emergency decision fast and scientific, meanwhile, the paper made an empirical analysis on Nanchang Railway Bureau. The results provide support and reference to reduce the time and cost for the scientific emergency rescue in railway.
