Darst. PY - 2010 N1 - Prüfungsjahr: 2010. - Publikationsjahr: 2011 N1 - Aachen, Techn. Hochsch., Diss., 2010 AB - 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.
