ACCESS Working Session
On 11-12 December 2013, the ACCESS Consortium gathered at a workshop kindly hosted by University Ca' Foscari in Venice to review the first two scientific/technical deliverables of the project (D1.1 'Performance of the Current Slot Allocation Process and Stakeholder Analysis Report' and D2.1 'Review of Auction-based Markets'). Both deliverables are now approved by EUROCONTROL and will be published through the project website before the end of the year. The meeting also served to discuss the third project deliverable D2.2 'Market-based Mechanisms for Airport Slot Allocation: Formalisation and Assessment Criteria', as well as the scope and high level requirements for the modelling work to be launched in 2014.
The first ACCESS scientific-technical deliverable is now available for download here. The document analyses the current system in terms of rules, actors, interactions and performance outcomes, identifies a number of options for reform, and discusses the expected impact for different stakeholders.

The second ACCESS scientific-technical deliverable is now available for download here. The document identifies and analyses theory and practice of auction markets to elaborate a useful set of recommendations to be used as starting point for the design of an auction market for airport slot allocation. Experiences in real auction markets across several domains are discussed, as well as the expected impact of this kind of markets on airport slot allocation.
ACCESS Working Paper 2: Review of Auction-Based Markets
February 18, 2014
Demand and capacity imbalances in Europe are set to become more prevalent. These are currently managed by mechanisms considered by many to be ‘unfair’. What are the alternatives being considered and are they really better for stakeholders? Are there better ways to manage these challenges and, if so, what do we need to do to implement them? Is current policy thinking on the right tracks? What exactly do we mean by ‘fairness’ and how do delay costs fit into the picture? Examining the potential future role of market-based demand management to redistribute air traffic in European airspace and to allocate airport capacity, the event was a day of lively debate and exchange amongst the key stakeholders in Europe. In addition to presentations from experts in the field, the programme included 4 break-out sessions for topic-focused discussions. Around 100 delegates from airlines, airports, slot coordinators, ANSPs, European and national policy makers and regulators, and professionals from industry and academia participated in the workshop, which was kindly hosted by the University of Westminster. More information about the event can be found here.

The third ACCESS scientific-technical deliverable is now available for download here. The paper describes and formalises the slot allocation mechanisms that will be simulated by ACCESS — describing the flow of information among stakeholders, the decision points, the solution of the slot allocation problem, or how to start up, configure and operate the system, among other aspects — and outlines a performance framework for the comparative evaluation of different slot allocation mechanisms along six performance areas: economic efficiency; equity and distributional aspects; access and competition; flexibility, resilience and adaptability; interoperability; capacity and delay.

Fourth SESAR Innovation Days (SIDs 2014)
The IEEE 9th International Conference on System of Systems Engineering (SoSE 2014) took place in Adelaide, Australia, from 9th to 13th June 2014. The conference is focused on the application of state-of-the-art complex systems research to management and policy problems. Our paper "System of Systems Engineering for the Airport Slot Allocation Problem" (M. Ramírez, A. Araúzo, F. Villafáñez, A. López), explaining the ACCESS approach to the airport slot allocation problem, was presented by Mario Ramírez.

The ACCESS Mid Term Review was successfully held in Brussels on 10th October with the participation of representatives from EUROCONTROL, the SJU and the European Commission. The work done so far was presented, the specification of the ACCESS simulation platform was reviewed in detail, and the work planned for the second half of the project was discussed.

The 135th IATA Slot Conference took place in Prague, Czech Republic, from 11th to 14th November 2014. With nearly 1000 delegates, from over 200 airlines and representatives of over 60 schedules-facilitated or fully coordinated airports, the goal of this semi-annual meeting is to provide a forum for the allocation of airport slots. Members of the ACCESS team participated as observers and had the opportunity to discuss the findings and the approach of the project with different airlines and airport coordinators.

ACCESS participated in the Fourth SESAR Innovation Days, which were hosted by the Technical University of Madrid, Spain from 25th to 27th November 2014. The SESAR Innovation Days are the main forum for dissemination of WP-E results, allowing interaction with the wider ATM research community and industry representatives. Mario Ramírez (INSISOC) presented the paper "Agent-Based Pilot Model for Alternative Primary Airport Slot Allocation with Price-Setting Auctions", which illustrates ACCESS research methodology through the simulation of a combinatorial slot auction in a simple scenario.
The second ACCESS stakeholder workshop was held on 19th May 2015 at ALG facilities in Barcelona. The main principles and assumptions of the ACCESS simulation model and the simulation scenarios were presented and discussed with representatives from airlines, slot coordinators, the SJU and EUROCONTROL, with the aim to refine our modelling approach and exchange ideas for future improvement.

The ACCESS Close-out Meeting was successfully held at the SJU premises in Brussels on 12th January 2016. The quality of the results and the ACCESS contribution to the understanding of the implications of market-based mechanisms for airport slot allocation were acknowledged by the SJU. The Close-out Meeting was followed by a Final Dissemination Event held at EUROCONTROL Headquarters on 13th January 2016. The Final Event included several technical presentations by the ACCESS partners providing an overview of the main project results, and a round table on future steps based on the outcomes of the project.

ACCESS Working Paper 6: Agent-Based Simulation of Airport Slot Allocation Mechanisms
The final ACCESS scientific-technical deliverable is now available for download here. The document provides an overall view of the ACCESS simulation platform and describes the simulation experiments conducted in the frame of the project. The first set of simulation experiments explores the use of combinatorial price-setting auctions for primary slot allocation. The experiments show the ability of the proposed auction to balance capacity and demand, and allow us to derive some guidelines for optimising the auction design. Then we present a second set of experiments aimed to compare the auction-based slot allocation and the current administrative slot allocation mechanism based on grandfather rights. These experiments show that the auction allows the allocation of scarce airport capacity to those airlines able to make best economic use of it and increases the total social welfare with respect to the current administrative system. At the same time, these experiments demonstrate the ability of the ACCESS simulation platform to capture the distribution of costs and benefits of different slot allocation mechanisms among different stakeholders. We conclude by discussing future lines of research for increasing the realism of the ACCESS simulation model, with aim of taking it to the point where it can be used for a comprehensive evaluation of the benefits and risks of market mechanisms and inform future policy developments.
