Abstract:
Objective To establish a simulated model that can optimize strategies for medical evacuation in case of mass casualties,and to study the guidelines for centralized scheduling of evacuation vehicles.Methods A simulated model was constructed based on theories about discrete event simulation and on processes of medical evacuation.Evacuation processes under different scheduling strategies were simulated and quantitatively evaluated in terms of efficiency of evacuation and utilization of resources.The impact of key parameters on the medical evacuation system was analyzed.Results When the critically wounded were given priority,the rate of immediate treatment for the wounded was the highest(87.44％),and the median waiting time for the wounded was 23.70 min.In terms of utilization of resources,the strategy of prioritizing the critically wounded delivered the best result,with an average of 2.94 persons evacuated per vehicle and an overall rate of vehicle utilization was 50.93％.The daily number of the wounded and the number of evacuation vehicles made a big difference in the performance of the rescue system.Command and scheduling had to be dynamically optimizedas required so as to strike a balance between the efficiency of treatment and utilizationof resources.Conclusion This simulated model for medical evacuation in case of mass casualties,which is based on theories about discrete event simulation,is flexible enough toback up the simulation of strategy optimization.
