Short-Term Flight Scheduling

Nowadays, air transportation industry is considered as one of the most important pivots of growth in developed and developing countries. Due to increasing growth and need to develop the infrastructure of this industry, the aviation sector enjoys a great importance. The intense competition between airlines and the increased level of passengers’ expectation, has led to considering complex scheduling and planning problems, so that requires new models and methods to solve these problems. Scheduling difficulties which principals of airports and airlines are encountering these days are much more complicated than conventional planning problems. In this paper, one mathematical model has been proposed for an airport flight scheduling in a horizon of one day, in which items such as fleet assignment, gate assignment and flight scheduling and sequencing has been considered. In this paper, flight scheduling is carried out so as to balance is created in various time intervals. In other words, the model tries to avoid flight congestion in one or more time intervals and to schedule flights moderately in different time intervals and also ensures different constraints of flight scheduling problem. This problem has been modeled as a mixed integer programming model and has been solved using an exact method with GAMS software.
