Improvement Airport Transportation Performance by Optimization Service Cars Performance Using Geospatial Information System

Despite the traffic increases at the World airports, little works have been done to improve vehicles and airplanes services, increase efficiency and decrease service automobile voluminous of large number. With GIS abilities, airport managers would like using its potential for development and management of airports. So new issue in GIS is formed with AGIS title to study GIS applications in airport as wide and corporation all world airports and GIS specialists.This paper presents an application of GIS analyses in airport field. The main innovation of this research is offline spatiotemporal data analysis and introducing an efficient algorithm for service automobiles allocation optimization with reduction in departure time deferment constraint. Allocation has been done by considering the aircraft push and tow required time and its distance to a service car. In this proposed solution servicing operation optimizes with considering two situations: one that service car returns to its Equipment Parking Area or EPA when delivering service and in another situation service car parks in Equipment Staging Area or ESA. Numerical results of using proposed method in Mehrabad international airport indicate in both situations, departure delay is lesser than usual method. Outcomes of minimizing service cars are: traffic reduction, increase management efficiency, decrease hazards due to large number of service cars and increase safety in airport field.
