In order to reach an optimum analysis and design for airport aprons variables such as the area and dimensions of the apron considering the passenger and cargo, the number and dimensions of the gates depending on the different type of aircraft, parking configuration and the arrangement of aircraft in different time periods at the airport has been looked into carefully. In this research a mathematical model for the optimum analysis and design of airport aprons based on minimum transportation cost has been developed. The main parameters considered for transportation cost are user capital and operational costs. Based on these parameters, a mathematical model as well as computerized simulation software have been developed taking into consideration the actual variables of design and analysis of airport aprons. The results obtained from the computerized simulation software indicate that the policies of the airport authorities and air carriers within the context of flight scheduling, gate use strategy, planning and analyzing the operational condition of the aircraft fleet have a significant impact on the planning and design of airport aprons.
