论文摘要
这项工作介绍了设施位置问题，以在巴西Minas Gerais的Belo Horizonte的一项名为Samu-BH的紧急医疗服务中获得最大覆盖范围。拟议模型的目的是为其救护车找到最佳地点，以便在必要时提供更快的现场帮助。首先，它开发了一个单一目标模型来最大化覆盖率，该模型定义为目标时间之前参加的呼叫数量。根据设施的位置和设备安置技术（车队）模型，提出了一种新型的数学模型，称为Fleet-IC，可以与独立的覆盖范围一起使用。其次，它提出了一个多目标模型，以增加总覆盖范围，同时减少安装碱的数量。结果表明，考虑到繁忙的分数因子，并且没有它，单瞄准模型的应用程序的应用将覆盖率提高了48％。它还分析了对额外救护车的覆盖率的影响。
This work presents the facility location problem for maximum coverage in an emergency medical service called SAMU-BH, located in Belo Horizonte, Minas Gerais, Brazil. The purpose of the proposed model is to find the best locations for its ambulances in order to provide faster in-site assistance whenever necessary. First, it develops a mono-objective model to maximize the coverage rate, defined as the number of calls attended before a target time. Based on the Facility Location and Equipment Emplacement Technique (FLEET) model, a novel mathematical model is proposed, called FLEET-IC, which can work with independent coverages. Secondly, it proposes a multi-objective model to increase total coverage while reducing the number of installed bases. The results show that the mono-objective model's application increases the coverage rate up to 48%, considering the busy fraction factor and up to 26% without it. It also analyzes the effect on the coverage rate of the inclusion of additional ambulances.
