Discrete-Event Simulation of Aviation Rescue Efficiency on Earthquake Medical Evacuation

Aviation rescue, or medical evacuation by aircraft, is becoming increasingly significant in the earthquake relief in China due to its high efficiency and high stability. This paper mainly investigates aviation rescue in earthquakes, using a discrete-event simulation method to build an aviation rescue model to study the impact of aviation rescue force on rescue efficiency. In this paper, two factors are considered as the aviation rescue force, namely the number of dispatch aircrafts and the support speed. The simulation results show that the marginal contribution of the number of dispatched aircrafts to the reduction of mortality rate is diminishing at a certain level of support, while the upper limit of the rescue effect is limited by the support speed
