The increase in world population and the value of time in the current period are changing the importance of air transportation. Due to increase popularity, airport officials have increased the number of flights. Because of the fact that the airports capacity is constant, airport traffic has increased. Regarding this, airport managers are looking for a solution to reduce traffic at airports and optimize the performance of service cars at the airport. The most important innovation of this research is developing a model for dynamic location of Equipment Parking Area (EPA) with optimal allocation of airport services in two different service modes. The goal of model is reducing costs and traffic and optimizing available spaces. To find optimal solution, two objective functions have been developed in the form of median and cover problems, and EPA locations have been located in a way that minimize the objective functions. The purpose of these functions are minimizing traffic at the airport and minimizing delays in flights. Using the developed model, EPA locations can be located for different time period flights and can be used to optimize the operations of the service cars without delay. The proposed model has been implemented for the Imam Khomeini International Airport and the results indicate that the number of service cars for nine flights has been decreased about 30% without any delay, as well as the amount of traffic have been decreased about 1300 meters in the first case and in 500 m in the second one.
