Download or read book Modeling and Optimization of Air Traffic written by Daniel Delahaye and published by John Wiley & Sons. This book was released on 2013-07-01 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book combines the research activities of the authors, both of whom are researchers at Ecole Nationale de l’Aviation Civile (French National School of Civil Aviation), and presents their findings from the last 15 years. Their work uses air transport as its focal point, within the realm of mathematical optimization, looking at real life problems and theoretical models in tandem, and the challenges that accompany studying both approaches. The authors’ research is linked with the attempt to reduce air space congestion in Western Europe, USA and, increasingly, Asia. They do this through studying stochastic optimization (particularly artificial evolution), the sectorization of airspace, route distribution and takeoff slots, and by modeling airspace congestion. Finally, the authors discuss their short, medium and long term research goals. They hope that their work, although related to air transport, will be applied to other fields, such is the transferable nature of mathematical optimization. At the same time, they intend to use other areas of research, such as approximation and statistics to complement their continued inquiry in their own field. Contents 1. Introduction. Part 1.

This book was released on 2017 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to a soaring air travel growth in the last decades, air traffic management has become increasingly challenging. As a consequence, planning tools are being devised to help human decision-makers achieve a better management of air traffic. Planning tools are divided into two categories, strategic and tactical. Strategic planning generally addresses a larger planning domain and is performed days to hours in advance. Tactical planning is more localized and is performed hours to minutes in advance. An aggregate route model for strategic air traffic flow management is presented. It is an Eulerian model, describing the flow between cells of unidirectional point-to-point routes. Aggregate routes are created from flight trajectory data based on similarity measures. Spatial similarity is determined using the Frechet distance. The aggregate routes approximate actual well-traveled traffic patterns. By specifying the model resolution, an appropriate balance between model accuracy and model dimension can be achieved. For a particular planning horizon, during which weather is expected to restrict the flow, a procedure for designing airborne reroutes and augmenting the traffic flow model is developed. The dynamics of the traffic flow on the resulting network take the form of a discrete-time, linear time-invariant system. The traffic flow controls are ground holding, pre-departure rerouting and airborne rerouting. Strategic planning---determining how the controls should be used to modify the future traffic flow when local capacity violations are anticipated---is posed as an integer programming problem of minimizing a weighted sum of flight delays subject to control and capacity constraints. Several tests indicate the effectiveness of the modeling and strategic planning approach. In the final, most challenging, test, strategic planning is demonstrated for the six western-most Centers of the 22-Center national airspace. The planning time horizon is four hours long, and there is weather predicted that causes significant delays to the scheduled flights. Airborne reroute options are computed and added to the route model, and it is shown that the predicted delays can be significantly reduced. The test results also indicate the computational feasibility of the approach for a planning problem of this size.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Traffic Management (ATM) aims at ensuring safe and efficient movement of aircraft in the airspace. The National Airspace System is currently undergoing a comprehensive overhaul known as NextGen. With the predicted growth of air transportation, providing traffic flow managers with the tools to support decision making is essential. These tools should aid in accommodating the air traffic throughput increase, while limiting controller workload and ensuring high safety levels. In the National Airspace System (NAS), the goal of en-route Traffic Flow Management (TFM) is to balance air traffic demand against available airspace capacity, in order to ensure a safe and expeditious flow of aircraft, both under nominal and perturbed conditions. The objective of this thesis is to develop a better understanding of how to analyze, model and simulate air traffic in a given airspace, under both nominal and degraded conditions. First, a new framework for en-route Traffic Flow Management and Airspace Health Monitoring is developed. It is based on a data-driven approach for air traffic flow modeling using historical data. This large-scale 3D flow network of the Cleveland center airspace provides valuable insight on airspace complexity. A linear formulation for optimizing en-route Air Traffic is proposed. It takes into account a controller taskload model based on flow geometry, in order to estimate airspace capacity. The simulations run demonstrate the importance of sector constraints and traffic demand patterns in estimating the throughput of an airspace. To analyze airspace degradation, weather blockage maps based on vertically integrated liquid (VIL) are incorporated in the model, representing weather perturbations on the same data set used to compute the flows. Comparing the weather blockages and the network model of the airspace provides means of quantifying airspace degradation. Simulations under perturbed conditions are then run according to different objectives. The results of the simulations are compared with the data from these specific days, to identify the advantages and drawbacks of the present model.

Download or read book Modeling and Forecasting of Staffing in Civil Aviation written by Anzhela Borzova and published by Springer Nature. This book was released on 2022-12-12 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights issues related to the organization and improvement of the efficiency of training system in technical operation of radio-electronic equipment currently used in civil aviation. The increasing intensity of air traffic around the world leads to a quantitative increase in old problems and the emergence of qualitatively new ones that can only be solved by trained people, whose training process should be carried out on a systematic basis. Modern approaches to improving the human resources potential of civil aviation, as a rule, are based only on modernizing the management mechanisms of the training system. One of the main advantages of this book is the unique integrated approach to building a system for training aviation personnel in the field of technical operation of radio-electronic equipment and air traffic control, which consists in taking into account various factors that affect the training of specialists, promising areas of development of civil aviation based on the analysis of various guidance documents and the construction of mathematical models that give a qualitative assessment of existing methods and the proposed new methodology. The book contains a large amount of visual illustrative material showing the existing structure of the system of training in the field of civil aviation.

Book Synopsis Real-time Trajectory Optimization and Air Traffic Control Simulation for Noise Abatement Approach Procedures by : Feng Zou
Download or read book Real-time Trajectory Optimization and Air Traffic Control Simulation for Noise Abatement Approach Procedures written by Feng Zou and published by . This book was released on 2004 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft noise is a major obstacle to the growth of aviation. This thesis presents an adaptive onboard real-time optimization algorithm and an Air Traffic Control simulation model that can minimize the aircraft approach noise and meet air traffic control targets and restrictions. The adaptive real-time optimization algorithm uses dynamic programming, nonlinear optimization, and receding horizon control to generate approach procedures. The resulting noise abatement trajectories compensate for environmental uncertainties, provide more flexibility to air traffic controllers and pilots, and improve airport efficiency while lowering community noise. The Air Traffic Control simulation model simulates a fleet approach with noise abatement approaches. Three different status displays are tested and compared in the simulation, and the optimal displays for controller are explored in the thesis.
Book Synopsis Optimization and Analytics for Air Traffic Management by : Michael Jacob Bloem

Available in PDF, EPUB and Kindle. Book excerpt: The air traffic management system is important to the United States' economy and way of life. Furthermore, it is complex and largely controlled by human decision makers. We studied and learned from these expert decision makers to facilitate the transition to an increasingly autonomous air traffic management system that leverages the strengths of both computer systems and humans to provide greater value to stakeholders. In particular, we constructed decision models and corresponding solution algorithms that enable decision-support tool development. Our approach to building the decision models and algorithms leveraged expert input and feedback, operational decision data analytics, fast-time simulations, and human-in-the-loop simulations. We utilized and extended techniques from optimization, dynamic programming, and machine learning both for developing solution algorithms and for making inferences about decisions based on operational data. In this dissertation we discuss our research on three types of decisions in the air traffic management system. The first is faced by supervisors of air traffic controllers: how to configure available airspace, controllers, and other resources to ensure safe and efficient operations in a region of airspace over a period of time. The second type of decision is faced by airlines: how to assign a set of flights to a set of slots in an Airspace Flow Program. The third type of decision is faced by air traffic flow managers: when to implement a Ground Delay Program.
Book Synopsis Optimization and Uncertainty Handling in Air Traffic Management by : Gaetan Marceau Caron

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we investigate the issue of optimizing the aircraft operators' demand with the airspace capacity by taking into account uncertainty in air traffic management. In the first part of the work, we identify the main causes of uncertainty of the trajectory prediction (TP), the core component underlying automation in ATM systems. We study the problem of online parameter-tuning of the TP during the climbing phase with the optimization algorithm CMA-ES. The main conclusion, corroborated by other works in the literature, is that ground TP is not sufficiently accurate nowadays to support fully automated safety-critical applications. Hence, with the current data sharing limitations, any centralized optimization system in Air Traffic Control should consider the human-in-the-loop factor, as well as other uncertainties. Consequently, in the second part of the thesis, we develop models and algorithms from a network global perspective and we describe a generic uncertainty model that captures flight trajectories uncertainties and infer their impact on the occupancy count of the Air Traffic Control sectors. This usual indicator quantifies coarsely the complexity managed by air traffic controllers in terms of number of flights. In the third part of the thesis, we formulate a variant of the Air Traffic Flow and Capacity Management problem in the tactical phase for bridging the gap between the network manager and air traffic controllers. The optimization problem consists in minimizing jointly the cost of delays and the cost of congestion while meeting sequencing constraints. In order to cope with the high dimensionality of the problem, evolutionary multi-objective optimization algorithms are used with an indirect representation and some greedy schedulers to optimize flight plans. An additional uncertainty model is added on top of the network model, allowing us to study the performances and the robustness of the proposed optimization algorithm when facing noisy context. We validate our approach on real-world and artificially densified instances obtained from the Central Flow Management Unit in Europe.

Download or read book Quantitative Problem Solving Methods in the Airline Industry written by Cynthia Barnhart and published by Springer Science & Business Media. This book was released on 2011-12-22 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews Operations Research theory, applications and practice in seven major areas of airline planning and operations. In each area, a team of academic and industry experts provides an overview of the business and technical landscape, a view of current best practices, a summary of open research questions and suggestions for relevant future research. There are several common themes in current airline Operations Research efforts. First is a growing focus on the customer in terms of: 1) what they want; 2) what they are willing to pay for services; and 3) how they are impacted by planning, marketing and operational decisions. Second, as algorithms improve and computing power increases, the scope of modeling applications expands, often re-integrating processes that had been broken into smaller parts in order to solve them in the past. Finally, there is a growing awareness of the uncertainty in many airline planning and operational processes and decisions. Airlines now recognize the need to develop ‘robust’ solutions that effectively cover many possible outcomes, not just the best case, “blue sky” scenario. Individual chapters cover: Customer Modeling methodologies, including current and emerging applications. Airline Planning and Schedule Development, with a look at many remaining open research questions. Revenue Management, including a view of current business and technical landscapes, as well as suggested areas for future research. Airline Distribution -- a comprehensive overview of this newly emerging area. Crew Management Information Systems, including a review of recent algorithmic advances, as well as the development of information systems that facilitate the integration of crew management modeling with airline planning and operations. Airline Operations, with consideration of recent advances and successes in solving the airline operations problem. Air Traffic Flow Management, including the modeling environment and opportunities for both Air Traffic Flow Management and the airlines.
