Location allocation for airport services with p-median & covering problems

Nowadays, regarding to the increase in traffic and so the decrease in operation efficiency and service efficiency, it is required to optimize in spatial and temporal parameters in airport. The main innovation in this research is, locating equipment parking area with airport services optimized allocation in two different service situations. One that service car returns to its Equipment Parking Area after serving service and in other situation service car parks in Equipment Staging Area. For finding best answer, two object functions with median and covering problems was considered. EPA stations that minimize mentioned object function was located as well. Purposed method in other time interval could be used to locating optimized EPA and reduce expenditures and traffic and best using of available spaces. Purposed method implemented in Imam Khomeini airport and result indicates efficiency of purposed method in reduce traffic and expenditure.
