Abstract

The rapid intervention of Advanced Life Support (ALS) and Basic Life Support (BLS) when an emergency arises is of vital importance for the welfare of citizens. Currently, these Emergency Medical Vehicles (EMV) are located, in the province of Valencia, in certain logistical bases according to the criteria of those responsible for the Emergency Medical Services (EMS). However, it is not possible to cover the entire population of the province within the stipulated maximum times of 12 and 15 minutes (depending on whether it is an ALS or BLS, respectively). For this reason, a maximum coverage model is used to relocate the EMV bases in order to minimize the amount of uncovered population in the province. Thanks to the proposed model, the total coverage defect of the province's population is reduced by more than half compared to the current distribution.

求解瓦伦西亚省紧急医疗车辆实际搬迁问题的混合整数线性规划
高级生命支持(ALS)和基本生命支持(BLS)在紧急情况下的快速干预对公民的福祉至关重要。目前,根据负责紧急医疗服务的人员的标准,这些紧急医疗车辆位于瓦伦西亚省的某些后勤基地。然而,不可能在规定的12分钟和15分钟的最长时间内覆盖全省所有人口(分别取决于它是ALS还是BLS)。出于这个原因,我们使用最大覆盖模型来重新安置EMV基地,以尽量减少该省未覆盖人口的数量。通过该模型,全省人口的总覆盖缺陷比目前的分布减少了一半以上。
