【摘要】：在对具有区间性质的铁路应急需求点分析的基础上,针对铁路应急服务设施备选点未知且需建数目给定的选址问题,对传统单阶段选址模型进行改进,提出了综合考虑应急服务公平性及响应时效性的双阶段组合选址模型,并结合实例,验证了模型及算法的有效性.针对备选点未知且需建数目给定情况下的铁路应急服务设施双阶段组合选址问题所得的选址方案,应急服务半径降低了21.7%,应急服务水平差异性减少了35.8%,提高了整个系统的应急服务水平.本文提出的双阶段组合选址模型既适用于局部范围的应急服务设施选址也适用于全国范围的铁路应急服务设施选址,适用于备选点未知且给定建设数目的应急设施选址也适用于存在多个备选方案多目标布局优化的应急设施选址问题.
[Abstract]:Based on the analysis of railway emergency demand points with interval nature, the traditional single-stage location model is improved to solve the problem that the number of railway emergency service facilities is unknown and the number of railway emergency service facilities is given. A two-stage combinatorial location model considering the fairness of emergency services and response timeliness is proposed. The validity of the model and algorithm is verified by an example. In view of the location scheme of railway emergency service facilities with two stages combination location problem, which has unknown alternative points and needs to be built with a given number of sites, The emergency service radius is reduced by 21.7m, and the difference of emergency service level is reduced by 35.80.The emergency service level of the whole system is improved. The two-stage combined location model proposed in this paper is suitable for the location of emergency service facilities both locally and nationally. It is suitable for the emergency facility location with unknown alternative points and given number of construction. It is also suitable for the emergency facility location problem with multiple options and multi-objective layout optimization.
