卫生保健系统在应对灾害事件时被归类为关键基础设施系统。对保健设施的有形破坏或其业务或供应链的中断可能会阻碍有效的应对，并加剧紧急情况的后果。即使医院或公共卫生设施没有受到灾难事件的直接影响，这些设施也需要在紧急情况下有效运行，以管理激增的能力。当基础设施系统因人为或自然灾害事件而受损时，通过这些系统提供的资源不足会影响其性能。在本文中，系统动力学仿真模型将被用来描述卫生保健设施的运行，包括不同服务区域(急诊室、重症监护病房、病房、手术室)之间的相互作用、设施内的病人流动以及为维持卫生设施的运行而提供资源(即水、电、医疗用品的运输)的基础设施系统的状况。这项研究的结果可能会帮助医院管理者制定灾难准备计划，提供有关入住率和等待进入服务区的患者的信息。
Health care systems are classified as critical infrastructure systems when responding to disaster events. Physical damage to health care facilities or disruption of their operations or supply chains could prevent an effective response and aggravate the outcome of an emergency situation. Even if a hospital or public health facility were not directly affected by the disaster event, these facilities are required to operate efficiently during an emergency in order to manage a surge of capacity. When infrastructure systems are damaged as a result of man-made or natural disaster events, insufficient supply of resources through these systems affects their performance. In this paper, a system dynamics simulation model will be used as a tool to represent the operation of a health care facility, including the interaction between the different service areas (emergency room, intensive care unit, wards, operating room), the flow of patients inside the facility, and the condition of the infrastructure systems that supply resources (i.e., water, power, transportation of medical supplies) to maintain the operation of the facility. The results of this study may assist hospital administrators in their disaster preparedness plans, providing information regarding the level of occupancy and patients waiting to enter the service areas.
