Description

<p>In recent years, the air transport industry and economies of European countries had encountered disruption significantly from a volcanic eruption. In Japan, there are many active volcanoes, and it is expected that large-scale volcanic eruptions will have a great impact. In the previous research, the authors formulated the aircraft evacuation problem for the risk of large-scale volcanic eruption and proposed an optimization model that minimizes the total evacuation time of each aircraft. However, this model did not consider temporary mitigation of airport capacity in an emergency and could not evaluate airport-side countermeasures. Therefore, we constructed an aircraft evacuation model including the relaxation of airport capacity as a variable in this study. In that case, we used CARATS Open data for the position of the aircraft, and the genetic algorithm to optimize the combination of aircraft evacuation destination allocation and airport capacity mitigation levels. As a case study, we assumed the eruption of Sakurajima and analyzed it.</p>
