Title: A Hierarchical Heuristic Approach for Solving Air Traffic Scheduling and Routing Problem with a Novel Air Traffic Model

Abstract: Efficient flight routing and scheduling plays an important role in air traffic flow management (ATFM), which aims to maximize the utilization of airport and en-route capacities to ensure safety and efficiency of air transportation. In this paper we first propose a novel discrete-time flow dynamic model for an air traffic network, consisting of airports, waypoints and air links, upon which we formulate an air flow routing and scheduling problem as an integer linear programming problem.
Considering the NP-hard nature of the problem, we present a novel hierarchical flow routing and scheduling approach, where the hierarchical architecture is derived naturally from the network containment relationship, and computation is carried out in a bottom-up manner, which relies on an incremental strategy. Upon resulting flow routes and schedules, a heuristic algorithm is carried out to determine flight plans for individual aircraft. The effectiveness of the proposed hierarchical approach is illustrated by realistic air traffic data in four ASEAN Flight Information Regions (FIRs).

Bio: Rong Su received the BE degree in Automatic Control from the University of Science and Technology of China in 1997, and the MASc and PhD degrees both in electrical engineering from the University of Toronto in 2000 and 2004, respectively. Since then he was affiliated with University of Waterloo and Technical University of Eindhoven before he joined Nanyang Technological University in 2010. His research interests include discrete event simulation, supervisory control, model based fault diagnosis, control of multi-agent systems, optimisation and scheduling with applications in smart buildings, smart manufacturing systems, power management and intelligent transportation systems. In the aforementioned areas, he has over 130 publications in journals, book chapters, and conference proceedings, and two patents. Dr Su is an Associate Editor for Journal of Discrete Event Dynamic Systems: Theory and Applications, Journal of Control and Decision, and Transactions of the Institute of Measurement and Control, and the Chair of IEEE Control Systems Society Technical Committee on Smart Cities.

Where: Meeting room 1
Theme: Operational Challenges in ATM

Speaker 1: dr. Tomislav Radišić  (University of Zagreb)

Title: The Effect of Trajectory-based Operations on Air Traffic Complexity
Abstract: Airspace capacity is limited primarily by the saturation of air traffic controllers’ capacity, whose workload increases as air traffic complexity increases. Implementation of trajectory-based operations (TBO) has been proposed as a way to reduce workload, but few studies have examined how TBO affects the air traffic complexity. This presentation deals with the results of the study, which compared complexity experienced by the air traffic controllers in real-time simulation environment involving the conventional operations and TBO.

: Impact of Continuous Climb Operations on the capacity of high-density TMA
Abstract: Continuous Climb Operations are the following step to optimise departure trajectories by minimizing fuel consumption, pollutants or noise emissions in the vicinity of airports. Moreover, these procedures has the distinctive factor that airlines could fly it without the interaction of any ATC clearances. These procedures will have a great impact on capacity of high-density TMA due to uncertainties associated to their climbing profiles (currently airlines do not share this information). Perhaps this capacity reduction will inhibit their use in high-density TMA.

Title: Agent-based modelling and simulation of risk of collision between a drone and a commercial aircraft
Drones are the flavour of the time. In the USA already more UAVs have been registered than manned aircraft in the past. Most of the drones are used as toys but there is also desire to fly for professional reasons in commercial airspace . From a collision avoidance perspective this poses a new risk as current TCAS II has not been designed to operate with non-TCAS equipped aircraft. Hence, a thorough safety analysis should be carried to identify whether UAVs with a new ACAS system can safely operate in airspace with TCAS II equipped aircraft.

Title: A Multi-Agent Operational Planning Model for Airport Stakeholders
Better collaboration is required to increase efficiency at airports among the many stakeholders involved in airport operational processes: ATC, airlines, de-icers, snow removal, baggage handling, etc. But how to integrate the goals and plans of each stakeholder? Here I present a multi-agent model for collaborative planning among stakeholders using principled negotiation. More specifically we’re looking at winter scenarios, where many stakeholder dependencies are at place.

Theme: Agent-based Airport Surface Traffic Planning

Speaker 1: MSc Jeroen Siebers
Airport Surface Traffic Planning as a Markov Decision Process
During ground movement, a lot of uncertainties are present that may be of influence on the taxi time for an aircraft. Not only in start time of the operation, but also during. Therefore, it is hard to predict whether aircraft have conflicting plans. Within my presentation, I will present a method that sets up a vector field that presents the optimal routing choice to make at each piece of taxiway present within an airport infrastructure. Values for arrival (end) time, holding and taxiing can be manipulated to influence the vector field and influence behaviour of aircraft.
