abstract = {Airport coordination is key in airport scheduling
activities at congested airports. In this strategic capacity
management process the allocation of slots – precisely
timed operation permits – is required for every take-off
and every landing. At this scheduling stage excess demand
may occur if the number of slot requests exceeds the number
of available slots. Conflict resolution includes both
rescheduling and rejecting slot requests. Consequently,
airport access cannot be realized as planned by some
airlines. This dissertation’s objective is the development
of a standardized approach to evaluate the scheduling and
slot allocation process. This evaluation is based on the
feasibility for demanding airlines to access airport
infrastructure as requested. Therefore the term “scheduled
delay” – defined as difference between requested and
allocated slot times – is introduced as performance
indicator. Scheduled delays allow assessing airport
coordination results quantitatively and transparently with
regard to airport access and can account for an airport’s
scheduling performance. Because this approach is unique in
air transportation sciences until now, the possible usage of
scheduled delays has been discussed accordingly. In Section
1 of this thesis the feasibility to access airport
infrastructure due to slot allocation decisions is
introduced as a relevant performance aspect in airport
coordination. Airport access is required by airlines to
offer transport services. Operational restrictions as well
as passenger habits determine the required access times.
Slots will not be allocated as requested, if conflict
resolution due to excess demand requires rescheduling or
rejection of some slots at least. This scheduling
performance aspect impacts on both airline and passenger
habits. Section 2 focuses on the airport coordination
process itself. With airport coordination data being
available for German coordinated airports (schedule periods
Summer 2005 and Winter 2005/2006), a detailed process
analysis is based on the developments at those airports. The
results of this analysis allow abstracting the airport
coordination process in Section 3. Slot demand (input
parameter and system load), conflict resolution (service
process) and allocated slots (output parameter and system
throughput) are classified as relevant parameters and
dependencies of airport coordination. Scheduled delay is
defined as scheduling performance indicator. It measures the
temporal deviation between requested slot time and allocated
slot time as resulting from conflict resolution. A delay
analysis shows significant differences at German coordinated
airports with regard to scheduling performance. The
empirical results confirm the assumption that when slot
utilization (slot demand vs. slot capacity) increases, the
average scheduled delays per allocated slot will rise. Since
the available airport coordination data does not allow a
precise and complete reproduction of this interdependency, a
deterministic model approach is defined to predict scheduled
delays depending on the level of slot utilization. The
conflict resolution as focal part of the airport
coordination is modeled. Section 4 finally discusses the
possible implementation of scheduled delays in airport
planning and management. Now a systematic airport
performance measurement framework can be established
including both airport scheduling and day-to-day operations.
The performance indicator‘s contribution to addressing
airport capacity and design issues is focal in its possible
usage. An airport’s capability and sufficiency to cope
with the given demand can be indicated reliably.},
