“Summerizing” the science

In the last few months, we have been busy at presenting the results of our research work at different conferences. For those of you that could not attend, here you have a short review!

First, several people from Innaxis attended the ECTL / FAA ATM Seminar 2015, in Lisbon, Portugal.

Seddik Belkoura presented a computational framework that compares flight trajectories (planned and executed) to detect all delay-generating events, and that can be used as a tool to identify the causes of non ATFM delay across any en-route system with the appropriate data. This algorithm extracts the probability distribution of the magnitude of a delay caused by one event per flight. From this, it has been possible to show the independence between the amplitude of en-route delay generated by a single event and the global delay of a flight. Additionally, a temporal and spatial assessment of the resilience of the en-route system to delay generation have been provided, which might lead to the identification of spatial zones that generates more delay, hence more fuel consumption, and to new tactical trajectory planification based on each ANS efficiency regarding en-delay recovery.

Additionally, Massimiliano Zanin gave a talk synthesising the results obtained in the POEM project, which we finished one year ago, and that was selected as one of the SESAR “Oustanding Projects” in 2014. We also had new results not presented until now. The focus of the talk was on the potential benefits of using a complex network approach to model the process of delay propagation. By using simple theoretical models, like a percolation process, it is possible to simulate different strategies for limiting delay propagation: all of this without extremely costly simulations, but just using known analytical results of network theory!

Both papers, Seddik’s and MZ’ ones, can be downloaded from the website of the conference.

The week after the ATM Seminar, MZ traveled to New York city, presenting the latest developments of the SecureDataCloud project at the IEEE SERVICES ’15. Impressive conference, with hundreds of attendees, and keynote talks from people of the level of Tsengdar J. Lee (NASA), Eric Brewer (Google) and Guruduth Banavar (IBM Research). In this case, the presentation had a much more applied flavour: describing the development of the software libraries for performing the secure computation, as required by the project and by the specifications suggested by the advising stakeholders. The development of the full system will be described in a paper, now under consideration, that we trust will be published shortly – so, stay tuned!

This is just a short abstract of the topics covered. So, if you need to know more, please contact the authors – and

Resilience2050. Workshop 24 Nov 2014


The workshop on Resilience opened the debate around the state-of-art in the context of resilience in the Air Transport System and its operations. Both the new discoveries made in the field by the FP7 project consortium, together with inputs from other teams researching in the field were welcome in this event attached to the SIDs in Madrid.

2nd Workshop on Data Science in Aviation, 21st May, Paris

After much success in 2013, we are happy to inform you The Innaxis Foundation and Research Institute is preparing the 2nd workshop on ‘Data Science in Aviation’: Recognizing the importance of the subject matter, the EUROCONTROL Agency Research Team (ART) has decided to host this workshop which will be held at the EUROCONTROL Experimental Centre in Brétigny on May 21, 2014.

Many business functions have entered into a new era of decision making as a result of increasing abilities to store, access and analyze data. Many companies are now focusing on managing information streaming from their different business activities and developing new analysis techniques for the information. The areas of aviation, planning, safety assessment, automation, performance assessment and many other applications can greatly benefit from this new approach, which in its broader context, is called Data Science.

Data science is a set of fundamental principles that support and guide the structured extraction of information and knowledge from data. Data science leans on well-known data-mining techniques, however, it goes far beyond these techniques with successful data-science paradigms that provide specific applications. Data science and data-driven decision making involve principles, processes and techniques for understanding phenomena via the automatic analysis of data with the ultimate goal of improving decision making.

Data Science is a multi-disciplinary endeavour combining a range of skills in a variety of fields. It sits at the intersection of different disciplines: complexity science, statistical physics, network theory, data mining, knowledge discovery, computer science, indexing techniques, stream data processing, data evaluation environments, scalable analytics, visualization and most importantly, strong domain expertise.

Details on this interesting workshop, agenda and registration information will be published in the next days in our website!

Innaxis looks forward to sharing their work in ATM at SIDS 2013 in Stockholm


As in every year, many of us are getting ready to participate in the SESAR Innovation Days, organised by Eurocontrol and the SJU, this year in Stockholm.

In 2013, Innaxis has been particularly busy in this research field and, just as in previous editions, we will be especially active during the SID. In any case, with the goal of stimulating discussions with you in different research areas, this email aims to give you a small briefing on how we are participating in Stockholm in this important event:

The ComplexWorld network has gone a long way in the last three years. Paula López ( will give a presentation on the first day providing details of the different activities and how the network is setting itself up for 2014. On Day 3 the network will hold the satellite event “Complex Metrics in ATM” and a PhD session. Please, do not hesitate to talk to Paula ( if you are interesting in more information on the network activities.

At Innaxis we have been working on passenger-oriented metrics for a few years now, crafting a detailed tool to compute those metrics focusing on the 4 hour door-to-door challenge of FlightPath2050 and now Horizon2020. On the second day of SID (27th Nov), our colleagues from the University of Westminster will present this tool and the initial results . As part of our efforts to improve the way performance is assessed in air transport, this year we also worked on other case studies, including scenarios in which there is no tool set available to correctly design ATM operational concepts. To tackle the challenges of changing ATM while still remaining in control of the performance assessment, it is critical to look into new ways of estimating KPIs. This is what the tool set developed by CASSIOPEIA has accomplished. A poster about this project and the tool set developed will be available at SID.

If you would like more information on the four hour door-to-door challenge in which Innaxis is currently engaged, the latest passenger metrics developed in POEM, or the most recent agent-based CASSIOPEIA modelling framework, please do not hesitate to contact the architect of these design tools for ATM, Samuel Cristóbal ( who will be at the conference over the whole week.

Data Science has been an area of major interest at Innaxis over the last few years and in October we organised the first Data Science Workshop for Air Transport, which was held in Madrid. We are working on different elements of an infrastructure to allow major data mining work for Air Transport on different fronts; from evaluating current delay propagation, resilience of airports and airlines against disturbances, to evaluating new paradigms on safety monitoring, all of which is based on powerful data analytics. We are very proud of our advancements in the area. On Tuesday the 26th, our colleague Massimiliano Zanin will present  a paper comparing traffic density as measured today (i.e., number of aircraft crossing a sector), with other measures based on data analytics. If you need any information about this interesting research topic, please contact Mass directly (

Information Management has also been an area of interest for us. In particular, we think the Data Science paradigms will only be fully enabled if data is shared across stakeholders and this can be achieved only if the right secure and encrypted mechanisms are put in place. We present as a poster a number of SecureDataCloud ideas for ATM. This will be of use on different fronts; safety and fuel consumption, among others. You should also talk to Mass if Information Management is your area of interest.

Last, but not least, we will also serve as rapporteurs and we will help Eurocontrol to extract some conclusions as well as provide our own views on future research avenues. Carlos Álvarez will take care of this during the closing session. Please, contact Carlos ( if you feel inspired by his words!

We hope we have many opportunities to interact next week and hope you find our activities interesting and motivating for future initiatives.

See you in Stockholm!

Innaxis brings together leading experts for Data Science in Aviation workshop


Nearly 60 industry experts, academics and professionals from the fields of data science and aviation gathered in Madrid on October the 15th to attend the first ComplexWorld Network’s workshop, ‘Data Science in Aviation‘.  The workshop provided the opportunity for experts in the field to  discuss ways knowledge from aviation data could be extracted in order to enhance our understanding of the air transport system’s behaviour and the complex relation among its elements.

The workshop was motivated by the challenge of extracting ground breaking insights from the large quantities of data collected in the air transport network. The aviation sector gathers and stores a large amount of unstructured, heterogeneous data – safety data and reports, flight plans, navigation data, airport data, radar tracks – from multiple sources – airlines, ANSPs and airports. While the collection of information through different data sensors is growing exponentially, the application of data science to the data has not.  The workshop looked at how to capture the new opportunities offered by the data and close the large opportunity gap between the potential offered and the current outcomes of its analysis.

Innaxis as coordinator of the ComplexWorld Network, through which the workshop was supported, led the data science in aviation workshop initiative. Innaxis brought extensive IT expertise and experience in data-science analysis techniques to the workshop. Innaxis’s expertise in these areas has been developed through the various research programmes in which it works and through its exposure to different data science applications in a variety of fields.

The outcomes of the workshop will be made available shortly. It is our hope that these outcomes, which include new research ideas and discussions from this dynamic meeting of experts, will result in greater discussion and debate around the topic from the community as a whole. So please keep in touch and check back if you’d like to be involved in the ongoing development in this area.

Resilience as a Resilient Concept


Two years ago the ComplexWorld Network started a thread on Resilience in Air Transport as part of its Position Paper which aimed at identifying long term innovative research fields. As a continuation of that initial work Innaxis is currently developing the Resilience2050 project, in partnership with a consortium of experts in the relevant lines of research, among them the King´s College of London. As experts in the environmental field, King´s College has brought to the project their broad and in-depth expertise on the study of resilience from very diverse social systems.

Our Innaxis colleague Hector reminded us in his first post the engineering perspective of the resilience concept. It is also interesting opening the mind to learn about its application to social systems, to where it has expanded from its original ecological domain. For a scientific concept, the way that the characteristic of resilience can be studied in such vastly different arenas is quite unique. It was first applied to materials engineering in the mid 20th century. Twenty-five years later it was first applied to systems, when it was introduced to the ecological field. Since then, a broad range of disciplines have included this concept as a line of research, and even the term psychological resilience has been rapidly adopted and spread since it was introduced more than 30 years ago, referring to the capacity of a person to manage stress and adversity. Since Hurricane Sandy and the US government’s policy response to make cities more resilient to climate related disasters, resilience has dominated conversations and studies relating to city planning and infrastructure.

Going through the different fields of relevance, one can start to achieve a broad understanding of the meaning of resilience, although proving a common agreed definition is not an easy task. What is indeed common to all applications of the resilience concept is the existence of two key parameters, on the one hand, an external agent that causes stress over the object or system of study and, on the other hand, a response to that stress that tends to recover its stable state. This trend of returning to normalcy is what provides more harmony to the different meanings of resilience and what makes it especially interesting to Innaxis and the ComplexWorld projects for it to be applied to the air transport system. The increasing mobility needs of the citizens across ever larger distances make society highly dependent on this transport medium. Enhancing its stability is a key factor that needs to be fostered to fulfill societal expectations. This is the general objective over which Resilience2050 was built: investigating the resilience of the Air Transport has a high potential of improving system behaviour understanding and, subsequently, its governance in a cost-effective manner.

But… What converts a “fashionable” word in an atemporal multidisciplinary concept? Why has this term been so well accepted in the different domains? Has this recently opened research line come to stay in the ATM field?

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.
