This book was released on 2012 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for air travel increases over the years and many busy airports operate close to their capacity limits, congestion at some airports on any given day can quickly spread throughout the National Aviation System (NAS). It is therefore increasingly important to study the operation of large networks of airports as a group and to understand better the interactions among them under a wide range of conditions. This thesis develops a fundamental tool for this purpose, enhances it with several capabilities designed to address issues of particular interest, and presents some early insights and observations on the system-wide impacts of various scenarios of network-wide scope. We first describe an analytical queuing and network decomposition model for the study of delays and delay propagation in a large network of airports. The Airport Network Delays (AND) model aims to bridge the gap in the existing modeling tools between micro-simulations that track aircraft itineraries, but require extensive resources and computational effort, and macroscopic models that are simple to use, but typically lack aircraft itinerary tracking capabilities and credible queuing models of airport congestion. AND operates by iterating between its two main components: a queuing engine (QE), which is a stochastic and dynamic queuing model that treats each airport in the network as a M(t)/Ek(t)/1 queuing system and is used to compute delays at individual airports and a delay propagation algorithm (DPA) that updates flight schedules and demand rates at all the airports in the model in response to the local delays computed by the QE. We apply AND to two networks, one consisting of the 34 busiest airports in the United States and the other of the 19 busiest in Europe. As part of the development of AND, we perform a statistical analysis of the minimum ground turn-around times of aircraft, one of the fundamental variables that determine delay propagation. In addition, we show that the QE, with proper calibration, can model very accurately the airport departure process, predicting delays at two major US airports within 10% of observed values. We also validate the AND model on a network-wide scale against field data reported by the FAA. Finally, we present insights into the complex interactions through which delays propagate through a network of airports and the often-counterintuitive consequences. In the third part of the thesis, we present two important extensions of the AND model designed to expand its usability and applicability. First, in order to provide a more accurate representation of NAS operations, we develop an algorithm that replicates quite accurately the execution of Ground Delay Programs (GDPs). The algorithm operates consistently with the rules of the Collaborative Decision-Making (CDM) process under which GDPs are currently conducted in the United States. The second extension is the implementation in AND of a deterministic queuing engine (D(t)/D(t)/1) which can be used as an alternative to the original stochastic QE. This deterministic model can be used to study delay-related performance in a future system that operates at a higher level of predictability than the current one, as the one envisioned by FAA in the Next Generation Air Transportation System. In the final part of the thesis we describe a Mixed Integer optimization model for studying the impact of introducing slot controls at busy airports. The model generates new flight schedules at airports by reducing the number of available slots, while respecting all existing aircraft itineraries and preserving all passenger connections. We test the model at Newark Airport (EWR) and conclude that, with a small schedule displacement (less than 30 minutes for any flight during the day), it is possible to obtain a feasible schedule that obeys slot limits that are as low as the IFR capacity of the airport. We test the new schedule in AND and find that the local delay savings that would result from "slot-controlling" EWR in this way are of the order of 10% for arrivals and of 50% for departures, while we may also expect a reduction of 23% in propagated delays to the rest of the US network of airports.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction: In the past several years many attempts have been made to model the probabilistic nature of airport runway operations using a queueing-theoretic approach to runway modeling. Early studies were limited by computational considerations to examination of systems only once they reached "steady state". These models were unable to reflect the characteristic hourly "rises" and "falls" of demand for runway use at major airports. Koopman was the first to include time-varying demand in a queueing model of a runway. He examined simple M(t)/M/l and M(t)/D/1 models with planes awaiting landing or takeoff placed in a single common queue. By using advanced numerical techniques he showed that the airport system equations can be solved recursively through the computer to exhibit the system behavior as a function of time. A later study by Hengsbach and Odoni extended these models to include the case of k independent runways. This study also resulted in a set of computer programs which increased tremendously the computational efficiency of this approach. In this report we explore, for the first time, time-dependent queueing-theoretic models in which landing and departing aircraft are kept in separate queues. This allows explicit acknowledgement of various sequencing strategies by air traffic controllers and computation of separate statistics for delays to landings and to takeoffs. The report is organized into several basic sections. Expanding on an idea introduced by Koopman, we begin with the development of a basic two-queue runway model under time-varying demand. We then present an extended model which more realistically reflects actual airport runway situations. Third, results from an experimental investigation with these models are presented, including comparisons with the earlier single-queue model. Section 4 is a discussion of the expected delay to aircraft in these two-queue systems. Finally, we mention some simple extensions and suggest directions for further study.

This book was released on 1977 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: A validation plan is presented for an airside simulation model. The plan stresses basic principles of validation and inherent problems associated with comparing simulation model delay estimates with observable real-world data. A methodology is proposed that consists of three major steps: (1) evaluation of model logic, inputs, and outputs; (2) comparison of model estimates with collected data; and (3) a sensitivity analysis of the delay simulation model. A Model Validation Group, established to oversee the validation process, is described. Suggestions are given on sources of data on airside operations for model inputs and for comparisons with model estimates. (Author).
