3. A mixed-integer model for the scheduling problem 

In this section we model the runway scheduling problem as mixed-integer programs. First, we only plan once and ignore uncertainties. So we can simplify Fig. 1 in the way that Input(0) is just the input into the Planner and the output of the Planner has no effect on the ATC world. Thus, all aircraft land/depart at their planned time. We assume a given set of flights F. We abstract from a real airport with many constraints and terms in the objective function. Our simple objective function, which may be replaced by a more complex one in the future minimizes the sum of the deviations from the scheduled times. Furthermore, we want to avoid inbound holdings and want to meet outbound slot constraints, i.e. departure time constraints in order to meet an acceptable given latest time tLT i . In our simulation we assume outbound slot sizes of 15 min. Slot sizes of this range are often used for balancing the demand capacities. Furthermore, each aircraft has a schedule time tST i . It is assigned an earliest possible time tET i , which is treated as a hard constraint. A violation of the latest time tLT i just results in bad objective function value as well as holdings or departure slot losses.
