本研究以一医院为例，利用人群密度模式模拟病患后送，并进行水平后送之运作分析。建议的离散事件仿真模型考虑了三种类型的患者分配特定的移动速度和区域从疏散;移动速度也根据该地区的人群密度而变化。我们评估的比例和转移优先级为每种类型的病人在病房的疏散时间的影响。在夜班期间，随着由两名护士用床单或毯子转移的1型患者的比例增加，后送时间增加。结果表明，转移优先级在1型和2型患者之间改变时，疏散时间只有轻微差异。医院只需要增加一名工作人员，以缩短夜班的后送时间。
This study conducts an operational analysis of horizontal evacuation in a hospital using a crowd density model to simulate patient evacuation. The proposed discrete-event simulation model considers three types of patients assigned with specific moving speed and areas from which to evacuate; the moving speed also varied according to the area's crowd density. We evaluated the effect of the ratio and transfer priority for each patient type on evacuation time in the ward. During night shifts, the evacuation time increased with the ratio of type 1 patients transferred by two nurses with sheets or blankets. The results showed only slight differences in evacuation times when transfer priority changed between type 1 and type 2 patients. The hospital required only one additional staff member to shorten the evacuation time during night shifts.
