AN OPTIMUM SCHEDULE FOR VARIABLE DEPARTURE TIMES

The problem is to minimize the number of aircraft required to fill a given airline schedule under the condition that each departure time is allowed to assume any value within some defined range. We Assume that the number of aircraft required for a schedule with fixed departure times has already been minimized. The reason for considering variable departure is as follows: it was noticed that in a schedule with fixed departure times there were cases in which a plane would arrive a few minutes after a scheduled departure time and this would necessitate assigning an additional aircraft to the departure. If, through the use of variable departure times, the departure could be delayed enough to allow a connection with the incomming flight an aircraft could be saved. We have developed a heuristic which we feel accomplishes this task.
