| 目的 利用计算机仿真技术,模拟不同条件下应急医疗救援过程,优化救援策略与资源配置。 目的 首先根据伤员到达与伤情特征,制定4种备选策略并逐一对其进行模拟研究;之后通过伤员等待时间与救治单元工作强度确定最优策略;最后,通过模拟分析伤员到达率与救治单元数量之间的关系,对救治策略与救援力量配置提出合理化建议。 结果 采用先离开先服务与"选组策略"能够有效减少伤员等待时间与救治人员工作强度;当紧急(非紧急)类伤员到达率增加时,在满足伤员救治要求的前提下,总的救治单元数量同步增加,其中紧急(非紧急)类救治单元数量增加较快。 结论 通过模拟不同策略下的应急医疗救援过程,确定了最优救治策略;救治单元数量与伤员到达率密切相关,通过估算伤员到达率与平均救治时间,可为救援力量配置提供定量参考。 |

| Objective To apply computer simulation technology for simulating the emergency medical rescue of different conditions and optimizing the rescue strategy and resource allocation. Methods Firstly, according to the characteristics of the arrival of the wounded and the state of injury, four alternative strategies were formulated and simulated. Secondly, the optimal strategy was determined by waiting time of the wounded and the working intensities of rescue unit. Finally, the reasonable suggestions for the rescue strategy and rescue force allocation were put forward by simulation analysis of the relationship between the arrival rate of wounded and the number of rescue units. Results First-leave-first-served and the select-units strategy could effectively reduce the waiting time of the wounded and the working intensity of the rescue unit. When the arrival rate of class A(B) of the wounded increased, the total number of rescue units increased at the same time under the premise of meeting the requirements of the medical rescue, with the number of A(B) rescue units increasing more rapidly. Conclusion By simulating the emergency medical rescue process using different strategies, the optimal rescue strategy can be determined; the number of the rescue units is closely related to the arrival rate of the wounded; estimating the arrival rate of the wounded and the average treatment time can provide reference for rescue force allocation. |
