自动体外除颤器（AED）是一种便携式设备，用于诊断和诊断心脏骤停患者。因此，AED被广泛安装在机场、学校、体育场馆等公共场所，法律要求在这些地方安装AED。然而，尽管它们有用，但AED大多安装在室内，室外覆盖范围有限。因此，本研究在户外放置AED进行研究。这项研究考虑了一个复杂的城市环境，使用行人网络数据集和网络障碍。我们借鉴了Teitz和Bart（1968）的启发式方法，该方法内置于ArcMap中的位置分配求解器中。本研究结果发现，研究区域内可放置455个AED，包括227个预装AED，因此可额外提供228个装置。与设置为实验组的10种不同安装方法相比，我们的测试结果发现，额外的安装能够覆盖10%至30%的实际院外心脏骤停病例。本研究的主要贡献是提出了一种新的方法，在最佳区域定位AED，同时考虑复杂的城市环境。我们预测，通过实施这项研究的结果，心脏骤停相关的死亡率将降低。
Automated external defibrillators (AEDs) are portable devices that defibrillate and diagnose sudden-cardiac-arrest patients. Therefore, AEDs are widely installed in public places such as airports, schools, sport complexes, etc., and the installation of AEDs is required by law in these places. However, despite their usefulness, AEDs are mostly installed indoors with limited coverage outdoors. Hence, this study conducts research in the placement of AEDs in outdoor locations. This study considers a complicated urban environment using a pedestrian network dataset and network barriers. We draw on the Teitz and Bart’s (1968) heuristic method that was built in the location-allocation solver in ArcMap. The results of this study found that a total of 455 AEDs, including 227 pre-installed AEDs, could be placed in the study area, thus providing an additional 228 devices. Compared with 10 different installation methods that were set as experimental groups, our test results found that additional installations were able to cover 10% to 30% more actual out-of-hospital cardiac-arrest cases. The main contribution of this study is the proposal of a new method in locating AEDs in optimal areas while considering complicated urban environments. We predict that the cardiac-arrest-related mortality rate would be reduced through implementing the findings of this study.
