The potential applications of modeling and simulation on flight supporting process are proposed. Using discrete event simulation (DES) method, the vehicle schedules in Airfield Station Flight Supporting in both active and passive supporting mode are modeled and simulated, based on which, an illustration is given on simulation platform ARENA. According to the simulated results, support time of active supporting mode under network situation can be reduced by 3.25 minutes compared with the traditional passive supporting mode, and the supporting efficiency is improved by 10.6%.
