Available in PDF, EPUB and Kindle. Book excerpt: "Traffic Flow Management (TFM), in coordination with Airline Operation Centers (AOC), manage the arrival and departure flow of aircraft at the nations airports based on the airport Arrival and Departure rates for each 15 minute segment throughout the day. The management of traffic flow has become so efficient in the U.S., that approximately 95% of the delays now occur at the airports (not airborne). Inefficiencies in the traffic flow occur when non-traffic flow delays (e.g. carrier, turn-around, aircraft swapping and non-terminal area weather) are super-imposed on the traffic flow delays. Researchers have correlated these non-traffic flow delays at airports with sets of causal factors and have created models to predict aggregate delays at airports on the time scale of a day. To be consistent with the way traffic flow is managed, a model of causal factors of delays in 15 minute segments would provide the analytical basis for improving the efficiency of TFM. This dissertation describes the development of multi-factor models for predicting airport delays in 15 minute segments at 34 OEP airports. The models are created using Multivariate Adaptive Regression Splines (MARS). The models, generated using historic individual airport data, exhibit an accuracy of 5.3 minutes for generated delay across all the airports, and 2.1 minutes for absorbed delay across all the airports. A summary of the factors that drive the performance of each airport is provided. The sensitivity of each of the factors is also analyzed. Analysis of the models indicates that the factors that determine Airport Delays in 15 minute segments are unique to each airport. The most significant factors that generate delays at most of the nation's airports are Carrier Delay, GDP Delay at the outbound destination, and Departure Demand Ratio. Because of the relationship between these factors, and the propagation of delays throughout the network, the only way to mitigate system-wide delays is via a holistic network approach. The implications of these results are discussed. The potential benefits from this research include providing: (1) researchers and analysts a method to identify systemic causes of delays in the NAS and study the trends of influential factors; and (2) airlines and Air Traffic managers a means to evaluate predicted delays while executing Traffic Flow Management initiatives"--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. National Airspace System (NAS) is inherently highly stochastic. Yet, many existing decision-support tools for air traffic flow management take a deterministic approach to problem solving. This study aims to focus on the random and dynamic nature of flight departure delays to provide a more ac-curate picture of the airspace traffic situation, improve the prediction of the airspace congestion, and advance the level of decision making in aviation systems. Several models were proposed in this work based on the trends and patterns demonstrated by the delays. These models show reasonable goodness of fit, robustness to the choice of the model parameters, and good predictive capabilities. They could further advance the Enhanced Traffic Management System that is currently adopted by the Federal Aviation Administration. Mathematical algorithms used in this work can be adapted to similar pro-blems in other fields. The book is addressed to professionals and researchers in Air Transportations and Statistics.

Available in PDF, EPUB and Kindle. Book excerpt: In total passenger miles, air travel has never been more popular. But as any frequent flyer knows, air travel problems are growing even faster - long lines, lost luggage, overbooking, flight delays, and serious safety issues. And instead of doing something about it, the traveling public seems simply to be sitting down, buckling in, and allowing itself to be treated like sheep.But it doesn't have to be this way. There are solutions to our air travel problems, real solutions that can make real differences. And they don't require 15 years to implement.With decades of experience in civil aviation and policy, Drs. George Donohue and Russell Shaver are well qualified to assess the problems in the system and offer responsible, workable solutions. Dr. Donohue, the current Director of the Center for Air Transportation Systems Research and a Professor of Systems Engineering at George Mason University (GMU), has extensive high-level experience at the Federal Aviation Administration and the Defense Advanced Research Projects Agency (DARPA). Dr.Shaver, formerly a senior RAND Corporation research analyst and now a visiting research fellow at GMU, served as chief scientist for policy analysis at the MITRE Center for Advanced Aviation System Development.The stories they tell are compelling. There are high-profile horror stories - passengers stranded for hours on the tarmac, flights cancelled for 'bad weather' when there's not a drop of rain anywhere near the flight path - as well as an overall sense of apathy and obstructionism among those responsible for managing the industry. Interestingly, these problems are not the inevitable result of the size or complexity of the U.S. system. Air transportation in Europe, with almost identical air traffic control systems and safety standards, is far better.Amsterdam moves 30 per cent more passengers than Newark, but the average flight delay is an order of magnitude lower. In addition, a European Passenger's Bill of Rights - giving distressed passengers the right to substantial and immediate compensation - has been a powerful incentive for non-U.S. airlines to maintain their schedules.So just how did we get where we are in the U.S. system today?Donohue and Shaver cite multiple reasons that have combined to create the chaos we now face. These causes include airline deregulation, multiple governmental agencies with no central oversight or responsibility, multiple corporate entities with conflicting agendas, and a technologically outdated air traffic control system. Even more importantly, there seems to be a complete absence of advocacy for the customer - the passengers. The authors also explain that our air travel problems, if left unaddressed, are on a direct course to greatly impact the overall U.S. economy and harm our global competitiveness. In 2006 alone, delays and cancellations cost U.S. travelers an estimated $3.2 billion. And in 2004 and 2005, the U.S. tourism industry is estimated to have lost $98 billion in revenue due to our air travel mess.Fortunately, Donohue and Shaver don't leave us in this state of chaos. Their provocative analysis not only identifies the causes and extent of the problems, but also provides us with a course heading to put us on the path to recovery.The solutions they propose include holding the government decision-makers responsible, expanding the capacity of airports and airplanes, modernizing the air traffic control system, and implementing what the authors call the '30 per cent solution' to significantly reduce congestion.In short, this book should be read by every airline passenger traveling in or through the United States. As a country, we simply can't afford to let the chaos continue.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together experts from research and practice. It includes the design of innovative Robot Process Automation (RPA) concepts, the discussion of related research fields (e.g., Artificial Intelligence, AI), the evaluation of existing software products, and findings from real-life implementation projects. Similar to the substitution of physical work in manufacturing (blue collar automation), Robotic Process Automation tries to substitute intellectual work in office and administration processes with software robots (white-collar automation). The starting point for the development of RPA was the observation that – despite the use of process-oriented enterprise systems (such as ERP, CRM and BPM systems) – additional manual activities are still indispensable today. In the RPA approach, these manual activities are learned and automated by software robots, either by defining rules or by observing manual activities. RPA is related to business process management, machine learning, and artificial intelligence. Tools for RPA originated from dedicated stand-alone software. Today, RPA functionalities are also integrated into elaborated process management suites. From a conceptual perspective, RPA can be structured into input components (sensors in the wide sense), an intelligence center, and output components (actuators in the wide sense). From a strategic perspective, the impact of RPA can be related to the support of existing tasks, the complete substitution of human activities, and the innovation of processes as well as business models. At present, high expectations are related to the use of RPA in the improvement of software-supported business processes. Manual activities are learned and automated by software robots that interact with existing applications via the presentation layer. In combination with artificial intelligence (AI) as well as innovative interfaces (e. g., voice recognition) RPA creates a novel level of automation for office and administration processes. Its benefit potential reaches a return on investment (ROI) up-to 800% that is documented in various case studies.
