ComplexWorld Workshop 2: Resilience and Robustness in ATM


2nd ComplexWorld Workshop. Toulouse, Wednesday 10th of July, 2013:

Taking place alongside the ATOS/ISIATM 2013 conferences, the 2nd ComplexWorld workshop will be held in the afternoon of Wednesday the 10th of July from 13:00 to 18:00 h.

The workshop will explore definitions, qualitative and quantitative evaluation (from a practical point of view) and modelling approaches to resilience and robustness in ATM.


  • To obtain a suitable representation of the states of an ATM system as well as a first quantitative evaluation of such states.
  • To discuss suitable modelling approaches that enable a realistic representation of an ATM system and allow us to achieve reliable results regarding the effects caused by disturbances.
  • To achieve (1) and (2) from an operational/practical perspective with support from industry experts.

Expected outcomes of the Workshop:

  • Review key features of definitions of resilience and robustness used in socio-technical systems.
  • Find state descriptions of an ATM system (from different stakeholder perspectives) by means of a specific set of performance indicators and their interdependencies.
  • Produce quantitative descriptions / formulations of a reference state of an ATM system from a practical point of view with the help of experts.
  • Determine modelling approaches to represent an ATM system in order to evaluate its resilience and/or robustness (from at least one particular perspective).

Discussion agenda

  • What are the various definitions of resilience and robustness? (Includes a short introduction of the terminology used and modelling approach proposed in Resilience 2050*).
  • How can we qualify and quantify resilience and robustness? What framework and suitable formulations/measures should we use for the evaluation of both system properties specifically in the ATM context?
  • How can we link this evaluation with the SESAR performance scheme? Which KPAs are directly relevant in this context?
  • Assessment of performance indicators and their particular interdependencies, including those between stakeholders, given by experts with a practical background.
  • Is cost the only workable common unit for KPI trade-offs and how do we assess strategic versus tactical trade-offs?
  • Suitable approaches to model a simplified ATM system as social-technical at one level of detail that is applied holistically.
  • In order to assess the boundaries of a particular modelled ATM system, what minimum level of detail should be considered when modelling?
  • How can we combine or use aspects of different approaches like simulation environments (e.g. AirTOp) and detailed models of complex social interaction w.r.t. safety aspects (e.g. work by NLR)?
  • What data are currently available to carry out some quantitative case study assessments and what data would be required (which are not yet available) to enable other case studies of key interest?
  • Identification of missing topics.

Note: The workshop will also consider work from DLR, UoW and their partners, e.g. on  Resilience 2050, an FP7 project already running (since June 2012), RobustATM (WP-E project, starting in September 2013) and ComplexityCosts (WP-E project, starting also in September 2013).

Currently we are trying to integrate some other WP-E projects and some of the PhDs already running. This page will be updated with these and any other new details as they become available.

ComplexWorld Seminar. Air Transportation Systems Conference


Incorporating the ComplexWorld 2013 Seminar. Toulouse, 8th to 11th of July 2013.

ComplexWorld will be holding its 2013 seminar at the 2013 Air Transportation System Conferences, which is being organized as four coordinated events including: ISIATM International Conference, Air Traffic Operations Symposium (ATOS); Association of Scientific Development of ATM in Europe (ASDA); and the ComplexWorld Seminar, exploring complexity science applications in ATM.

These concurrent conferences will be held in Toulouse, France at ENAC from the 8th to the 11th of July 2013.The format of the conference has been designed alternating plenary sessions with keynote speakers with parallel sessions coordinating the schedule in such a way that all attendees can decide which of the sessions is more relevant for him/her at any time.

The ComplexWorld seminar is intended as a forum to bring together researchers from academia, research establishments and industry, that share common interests and expertise in the field of Complexity Management, which lies at the intersection of Complexity Science and Air Traffic Management. It will focus on applied solutions (concepts and developments) in areas that explore how Complexity Science can contribute to understand, model, and, ultimately, drive and optimise the behaviour and evolution of the ATM system that emerges from the complex relationships between its different elements.

The CW event will present three different but related activities:

  • *The CW paper sessions (9th July) on relevant topics including Complex Systems modelling, emergent behaviour, data analysis, aviation metrics and safety. During this session, a presentation of the ComplexWorld Wiki will be given;
  • *A workshop on the topic of Resilience in Air Transport (10th July in the afternoon); and
  • *The Tutorials (11th July in the morning) given by key experts in the fields of Data Science in ATM, Intermodality Complexity, Non-determinism and Uncertainty, and Delay Patterns and Propagation of delays.

Registration for the ComplexWorld Seminar can be completed on this page, which also gives you access to all of the parallel conferences. If you are interested in attending only the Workshop on Resilience and/or the Tutorials, please send us an email to

ComplexWorld Workshop: Uncertainty in ATM


1st ComplexWorld Workshop: Uncertainty in ATM; definitions, sources, scales, challenges. Naples, Monday 27th of May, 2013, 13:00 to 18:00 h.

The objective of this workshop is: To obtain a critical review of the contents of the Section “Uncertainty on ATM” of the Position Paper (also included in the article “Uncertainty in ATM” in the ComplexWorld Wiki.) by researchers and project managers with different points of views (industry, academia and institutions)

Expected Outcome: Assessment of the research agenda proposed in the Position Paper.

Discussion agenda:

  1. Review of the definition of uncertainty. Is it possible to provide a unique definition? Given that uncertainty has an uncertain meaning (since it depends on the point of view), is it too ambitious to cover all possible concepts of uncertainty? Should one speak of different types of uncertainty? Should we just consider delay?
  2. Review of the classifications of the sources of uncertainty. Advantages and drawbacks as opposed to other classifications, for instance the classification according to the cause of occurrence: human, meteorological, technical and transparency of data.
  3. Review of the different scales identified in the ATM problem. Is there any relevant scale missing?
  4. Review of the research lines selected to analyze the research theme “Uncertainty in ATM” (selection based on the scales of the problem). Advantages and drawbacks as opposed to other selections. For example, a selection of research lines based on the different ATM actors: passenger, pilot, air controller, airline, airport, air navigation service provider.
  5. Review of the soundness of the different research challenges and case studies identified. Are they relevant, realistic, interesting? Comparison with the research challenges and case studies being considered by WP-E projects and PhDs that deal with uncertainty.
  6. Review of specific issues:
    1. Relationship between uncertainty and delay,
      Relationship between uncertainty and airport congestion,
      Relationship between uncertainty and safety,
      Relationship between uncertainty and wind/weather.
    2. Importance of the development of metrics for uncertainty. How is uncertainty measured by numbers? Strongly related with the type of uncertainty considered (e.g. delay).
    3. Advancement in the description of uncertainty caused by strong disturbances. Is considering only delay uncertainty enough to describe this type of uncertainty? What about other sources?
  7. Identification of missing topics.

To prepare the Workshop the following CW 2013 WS 1_Questionnaire will be sent to Participants some weeks before the meeting.

ECCS’12 Satellite Event


Complexity Paradigms for Smart, Green and Integrated Transport 2012

Welcome to the website of the Complexity Paradigms for Smart, Green and Integrated Transport 2012, a one day Satellite Meeting organized inside the European Conference on Complex Systems 2012 in Brussels.

Scope of the Meeting

The objective of this meeting is to assess the problems of transportation systems through Complex Systems theory and methodologies. Transportation Systems are composed of a large number of heterogeneous elements; interacting, perceiving different information from the environment, and pursuing heterogeneous/different aims. Examples range from very well known systems, like road traffic dynamics, up to new fields, such as the Air Transport Network. Plenty of examples can be found in the literature about how different Complex Systems tools can be used to understand the internal dynamics of those systems, from Complex Networks, up to percolation and self-organization.

The meeting aims to create a space for exchanging state-of-the-art results and ideas on this interesting topic. Special attention will be devoted to applications, i.e., how those tools and techniques can be used to improve the performance of real systems. Contributions centered on societal and environmental aspects and citizens’ perceptions will be especially welcome.

The Call for Papers

Submission of contributed papers can be made by sending an extended abstract (max. 3 pages) to the organizers (see email addresses below). Standard LaTeX, PDF, or Microsoft Words formats are encouraged. Submissions will be evaluated and selected by the program committee members, based on the adherence to the theme of the satellite, originality and scientific soundness. Once the selection process is complete, the authors of the accepted abstracts will be notified by e-mail.

The deadline for abstract submission for oral contributions is May 27, 2012. UPDATE: In response to a number of requests the submissions period has been extended – the new deadline is July 1st, 2012.

European Physical Journal Call for Papers: ¨Spatially Embedded Complex Networks¨

Last month, a researcher of Innaxis, Massimiliano Zanin, along with Fabrizio Lillo of the Scuola Normale Superiore di Pisa, organized a Satellite Meeting inside the European Conference on Complex Systems (ECCS ’11) in Vienna. This Satellite, called Complexity and the Future of Transportation Systems, was focused on the actual problems in the planification and management of transportation systems (from streets in a city, up to airline networks), and on how Complexity Science can propose new ways of tackling such challenges.


As a consequence of the success obtained by this event, both researchers have now been invited to act as Invited Editors for a specific issue of the journal European Physical Journal – Special Topics, called “Spatially Embedded Complex Networks”. This issue will be devoted to the application of the graph theory (and of the more recent complex network theory) to different transportation systems, both from the theoretical and applied point of view.


If you are interested in sending a contribution, do not hesitate in contact our researcher, and check this Call for Papers.
