Air Traffic Management (ATM) systems are complex systems of systems. Understanding all possible consequences of a design decision in an ATM system is a challenge due to the complexity of ATM systems and the existence of tight interdependencies within the ATM architecture. Knowing the implications of change(s) over the whole system is crucial to support decision-making, while making sure that the ATM system does not suffer from any issues with respect to functionality, safety, security, performance, cost efficiency, or other desired characteristics of a well-functioning ATM system. Given that decision-making involves the consideration of more high-level objectives, the change management process should involve multiple ATM domain stakeholders, one for each given objective, in order to explore a vast space of alternatives and agreeing on optimal solutions. It becomes, thus, crucial the active participation of stakeholders. However, given the variety of experts, their different areas of expertise, as well as their geographical distribution, participatory change management requires user engagement and tools to support and facilitate the work of experts along their interaction.

To address the first concern, in recent years, gamification is broadly used as a tool to engage participation with the help of elements, such as leader-boards or challenges between users. On the other hand, a multi-perspective, model-based approach provides important benefits in that:

  • it allows analyzing individual perspectives without the need of a holistic representation;
  • it handles complexity through automated reasoning techniques in a transparent way to find optimal solutions as a trade-off among different objectives.

Tutorial Part 1

We provide an overview of the participatory change management process, emphasizing the importance of active stakeholder participation. We describe the two main support tools, i.e. gamification for stakeholder engagement, and automated reasoning techniques for handling complexity.

Focus on: Participatory process, Gamification & Automated reasoning techniques

Tutorial Part 2

We introduce the PACAS approach, expressly created for architectural change management in ATM systems. We briefly describe an ATM example case study dealing with the Sectorless change issue, and conclude with a demo of the framework.

Focus on: ATM case study & Demo
